One or more terminals 20 can be connected.

The system 1 is a system that displays a graph of a function based on the calculation result based on a mathematical formula (function) input by the user, and displays a statistical graph or statistical value based on the result of statistical calculation based on numerical values. In the system 1, data and calculation instructions input to the terminal 20 are transmitted from the terminal 20 to the server 10. The server 10 executes calculations based on the data and calculation instructions, and transmits the calculation results to the terminal 20. The terminal 20 receives the calculation result and displays a display based on the calculation result, for example, a graph display or a statistical calculation result (text information).

The server 10 includes a processor 11, a ROM 12, a RAM 13, a storage 14, and a communication device 15. Each of these is connected to each other via a system bus 19.

It may be the same color as 152. This allows the user to easily understand the correspondence between each mathematical formula displayed on each mathematical formula sticky note 104a, 104b and each slider 118, 119 displayed on each slider sticky note 105a, 105b.

[Second group]
The graph sticky note 103, the numerical table (statistics) sticky note 107, and the statistical calculation sticky note 108 can be linked as a second group. In this specification, this state may be described as a graph sticky note 103, a numerical table (statistics) sticky note 107, and a statistical calculation sticky note 108 being grouped together. In the system 1, for example, a graph of the statistical calculation result is displayed on the graph sticky note 103 based on the numerical value input in the numerical table 111 of the numerical table (statistics) sticky note 107, and a statistical calculation that displays information related to the statistical calculation result. A sticky note 108 is created. FIG. 2 shows strings 146 and 147 indicating that the numerical table (statistics) sticky note 107 is tied to the graph sticky note 103 and the statistical calculation sticky note 108, respectively.

The third tab 114 of the graph sticky note 103 and the tab 153 of the first statistical calculation sticky note 108a may be displayed in the same color so that the association can be seen at a glance. The fourth tab 115 of the graph sticky note 103 and the tab 154 of the second statistical calculation sticky note 108b may be displayed in the same color. The color of the lines and points of the graph displayed on the graph sticky note 103 may also correspond to the color. Further, although not shown, each of the strings 144, 145, 143 may be composed of two strings parallel to each other, similar to the strings 144, 145 described above. The color of one of the two strings is the same as the color of the third tab 114 of the graph sticky note 103 and the color of the tab 153 of the first statistical calculation sticky note 108a. The color of the book string may be the same as the color of the fourth tab 115 of the graph sticky note 103 and the tab 154 of the second statistical calculation sticky note 108b.

Note that in FIG. 2, one graph sticky note 103 belongs to both the first group and the second group. In this embodiment, it is possible to draw both a function graph and a statistical graph on one graph sticky note 103.

In FIG. 2, a menu icon bar 50 is shown. The menu icon bar 50 accepts a user operation (for example, a right-click operation using a mouse, a touch-on operation on a touch panel, etc.) to specify an arbitrary position in an area where no object is placed in the paper 100. The screen is displayed at a position determined based on the position specified by the user's operation (the specified position or a position near the specified position). The menu icon bar 50 is a floating object, similar to a sticky note.

The menu icon bar 50 includes a calculation icon 51, a mathematical formula icon 52, a graph icon 53, a numerical table (statistics) icon 54, a geometry icon 55, and a memo icon 56.

This is an icon that receives an input operation for displaying a sticky note 203 (described later with reference to FIG. 29) and a memo sticky note 101. Various sticky notes created in response to input from the menu icon bar 50 are created and displayed without being linked to other sticky notes. That is, when a sticky note is created from the menu icon bar 50, it is not grouped with other sticky notes and is independent from other sticky notes.

As described above, FIG. 2 shows a state in which the graph sticky note 103 is selected. In this state, the icon group 60 is displayed on the graph sticky note 103. The icon group 60 includes a mathematical formula icon 61, a numerical table (statistics) icon 62, and a calculation icon 63. The mathematical formula icon 61 is an icon that receives an input operation to create a mathematical sticky note 104 linked to the graph sticky note 103 or to move the focus to an existing mathematical sticky note 104 linked to the graph sticky note 103. The numerical table (statistics) icon 62 is an icon that receives an input operation for displaying the numerical table (statistics) sticky note 107 associated with the graph sticky note 103 . The calculation icon 63 is an icon that receives an input operation to display the calculation (α+β) sticky note 110 associated with the graph sticky note 103.

In this embodiment, the system 1 starts from a blank piece of paper 100, creates various sticky notes, draws a desired function graph or statistical graph on the graph sticky note 103, or marks any point on the drawn graph.

In step S142, the CPU 21 determines whether there is a numerical table (statistics) sticky note 107 associated with the graph sticky note 103. The number table (statistics) sticky note associated with the graph sticky note is the number table (statistics) sticky note linked to the graph sticky note, that is, the number table (statistics) sticky note that is grouped with the graph sticky note. If it is determined that the numerical table (statistics) sticky note 107 exists (Yes), the process proceeds to step S143.

On the other hand, in step S144, the CPU 21 executes a process of creating a new numerical table (statistics) sticky note 107 associated with the graph sticky note 103 as a graph sticky note creation process. The CPU 21 automatically selects a position that does not overlap with other sticky notes and determines it as the display position of the numerical table (statistics) sticky note 107.

In step S152, the CPU 21 determines whether there is a calculation (α+β) sticky note 110 associated with the graph sticky note 103. The calculation (α+β) sticky note associated with the graph sticky note is a calculation (α+β) sticky note that is tied to the graph sticky note, that is, the calculation (α+β) sticky note that is grouped with the graph sticky note. If it is determined that the calculation (α+β) sticky note 110 exists (Yes), the process proceeds to step S153. If it is determined that there is no such information (No), the process proceeds to step S154.

In step S153, the CPU 21 executes a process of creating a new calculation (α+β) sticky note 110 by connecting it to the lower side of the existing calculation (α+β) sticky note 110. The display positions of the calculation (α+β) sticky notes are such that the new calculation (α+β) sticky note 110 is adjacent to the bottom of the existing calculation (α+β) sticky note 110, and the new calculation (α+β) sticky note 110 and the existing calculation (α+β) sticky note 110 are adjacent to each other. This is the position where the and are displayed vertically.

On the other hand, in step S154, the CPU 21 executes a new calculation (α+β) sticky note creation process. The CPU 21 automatically selects a position that does not overlap with other sticky notes and determines it as the display position of the calculation (α+β) sticky note.

After step S153 or step S154, in step S155, the CPU 21 displays the calculation (α+β) sticky note 110. After step S155, the process returns.

FIG. 9 is a diagram showing an example of the calculation process (step S18 in FIG. 3). In this embodiment, the calculations are performed by the server 10. The server 10 executes the calculation according to the calculation program of the server 10 based on the calculation instruction and information necessary for the calculation obtained from the terminal 20, and returns the calculation result to the terminal 20.

In step S181, the CPU 21 determines whether an input for performing an operation has been received. When the CPU 21 receives input operations and confirmation operations for various sticky notes (hereinafter collectively referred to as "input confirmation operations") in step S16 described above, the CPU 21 determines that an input to perform an operation has been received, and performs step S16. If the input confirmation operation is not accepted in , it is determined that the input for performing the calculation is not accepted. If it is determined that the request has been accepted (Yes), the process proceeds to step S182. If it is determined that the request has not been accepted (No), the process returns.

In step S182, the CPU 21 acquires calculation instruction information in response to input confirmation operations for various sticky notes, specifies necessary information, and transmits the necessary information to the server 10.

Specifically, when the input of a mathematical formula to the mathematical sticky note 104 is confirmed, information including the entered mathematical formula and the coordinate range of the graph display area is specified as necessary information and transmitted to the server 10 (see FIG. (information necessary for the processing of Steps S19 and S20 of Step 3). After inputting numerical values to the numerical table (statistics) sticky note 107 and selecting the statistical calculation type, information including the input finalized numerical values and the statistical calculation type is specified as necessary information and transmitted to the server 10 (Fig. (information necessary for the processing in step S21 of 3). When the numerical table (formula) icon 72 of the mathematical formula sticky note 104 is selected, information including the mathematical formula that has been entered into the mathematical formula sticky note 104 is identified as necessary information and transmitted to the server 10 (see FIG. 3). (information necessary for the process of step S22). When the input of the calculation formula to the calculation sticky note 102 or the calculation (α+β) sticky note 110 is confirmed, information including the input confirmed calculation formula and, if necessary, the values of variables in the calculation formula, etc., is specified as necessary information. The information is then transmitted to the server 10 (information necessary for the process of step S23 in FIG. 3).

In step S183, the server 10 receives the necessary information and executes calculations for graph drawing, calculations such as statistical calculations, four arithmetic calculations, etc. according to the calculation program based on the necessary information.

Specifically, the server 10 calculates the necessary information for drawing the graph sticky note 103, such as the coordinates of each point composing the graph, based on the necessary information including the mathematical formula entered into the mathematical sticky note 104 and the coordinate range of the graph display area. The data is obtained by calculation (processing in step S19 in FIG. 3). The server 10 also draws graph sticky notes 103, such as the coordinates of each point constituting the graph as a statistical calculation result, based on the necessary information including the numerical values entered and confirmed in the numerical table (statistics) sticky note 107 and the type of statistical calculation. The necessary data is calculated by calculation (processing of step S19 in FIG. 3). Furthermore, based on the necessary information including the formula entered into the formula sticky note 104 and confirmed, the server 10 inputs data necessary for drawing the slider sticky note 105, such as slider variables (characters), numerical range, default value, etc., if necessary. It is determined by calculation (processing of S20 in FIG. 3).

The server 10 calculates the data necessary for drawing the statistical calculation sticky note 108, such as the statistical calculation result, based on the necessary information including the numerical values entered into the numerical table (statistics) sticky note 107 and the type of statistical calculation (FIG. 3). (processing in step S21). The server 10 generates data necessary for drawing the numerical table (formula) sticky note 106, such as predetermined independent variable values and corresponding dependent variable values, based on necessary information including the formula that has been input into the mathematical sticky note 104. It is determined by calculation (processing of step S22 in FIG. 3). The server 10 writes information such as the numerical value of the calculation result to the calculation sticky note 102 based on the necessary information including the calculation formula that has been input into the calculation sticky note 102 or the calculation (α+β) sticky note 110 and, if necessary, the values of variables in the calculation formula. Alternatively, calculation (α+β) calculates data necessary for drawing the sticky note 110 (processing in step S23 in FIG. 3).

Further, in step S183, the server 10 transmits the thus obtained data necessary for drawing each sticky note to the terminal 20 as a calculation result.

In step S184, the terminal 20 receives the calculation result. The terminal 20 stores the received calculation result in the storage 24. After step S184, the process returns.

In this way, by performing various calculation processes on the server 10 instead of the terminal 20, complex calculation algorithms can be hidden without being disclosed. Furthermore, this allows even a terminal 20 with relatively low processing power or a general-purpose application such as a web browser to provide execution results of complex calculations.

FIG. 10 is a diagram illustrating an example of graph sticky note processing (step S19 in FIG. 3).
In step S191, the CPU 21 determines whether or not the data necessary for drawing the graph sticky note 103 described above has been received from the server 10 as the graph calculation result in the previously described step S18 (step S184). If it is determined that the graph calculation result has been received (Yes), the process proceeds to step S192. If it is determined that the message has not been received (No), the process returns.

The presence or absence of the graph sticky note 103 is determined. If it is determined that the formula sticky note 104 or the numerical table (statistics) sticky note 107 is present (Yes), the process proceeds to step S193. If it is determined that there is no such information (No), the process proceeds to step S194.

In step S193, the CPU 21 sets the target for drawing a graph to the existing graph sticky note 103 based on the graph calculation result.

On the other hand, in step S194, the CPU 21 sets the new graph sticky note 103 as a target for drawing a graph based on the graph calculation result.

The presence or absence of a character coefficient (corresponding to a character coefficient in the sticky note 104) is determined. If it is determined that the variable exists (Yes), the process advances to step S202. If it is determined that there is no such information (No), the process proceeds to step S204.

If it is determined that the same variable does not exist (No), the process advances to step S205. If it is determined that there is one (Yes), the process advances to step S206.

In step S206, the CPU 21 executes processing to generate slider sharing information. After step S206, the process returns.

After step S203 or step S205, in step S207, the CPU 21 updates the display. After step S207, the process returns.

FIG. 20A is a diagram illustrating an example of operations and displays related to the combination process. The terminal 20 receives the combination operation instruction and generates combination information as described below.

The sticky notes to be operated in the combining process are the graph sticky note 103, the mathematical formula sticky note 104, the numerical table (statistics) sticky note 107, the numerical table (mathematical formula) sticky note 106, and the statistical calculation sticky note 108. The sticky note to be operated and the sticky note in the same group as the sticky note are each combined with the same type of sticky note.

As a combining operation, the user selects one sticky note and moves it to the other sticky note so that it overlaps with the other sticky note (for example, a drag-and-drop operation). Let us say that the position specified by the input device 25 when the join operation starts is the "join operation start position", and the position specified by the input device 25 when the join operation is finished is the "join operation end position". For example, the combining operation may be instructed when the combining operation end position is within the range where the other sticky note is displayed.

Here, the two sticky notes are of the same type. The terminal 20 receives the combination operation instruction and combines the one sticky note with the other sticky note. Here, merging refers to merging the contents displayed on two sticky notes and displaying them together in one sticky note, as well as hiding (disappearing) one sticky note (hereinafter referred to as "combining sticky notes"). ), and arranging two sticky notes and displaying them as a single sticky note unit by connecting them (adjacent) (hereinafter sometimes expressed as "aligning sticky notes"). including. At this time, not only the sticky notes to be operated are combined, but also other sticky notes linked to the sticky note to be operated are either merged with the same type of sticky notes or arranged with the same type of sticky notes. Is displayed. In addition, in accordance with this combination operation, the coordinate value sticky note and calculation sticky note that are tied to the sticky note to be operated, or to the graph sticky note that is tied to the sticky note to be operated, disappear (become hidden). Become).

In the present embodiment, the terminal 20 has a mathematical formula sticky note 104 or a numerical table (statistics) sticky note 107 as a first input display area in which functions or numerical values are input and displayed, and is linked to the first input display area. , a graph sticky note 103 or a statistical calculation result sticky note 108 as a first calculation result display area in which main information related to the calculation result based on the function or numerical value inputted to the first input display area is displayed; A mathematical formula sticky note 104 or a numerical table (statistics) sticky note 107 serving as a second input display area in which a function or a numerical value is input and displayed is linked to the second input display area and is connected to the second input display area. A graph sticky note 103 or a statistical calculation result sticky note 108 as a second calculation result display area in which main information related to the calculation result based on the input function or numerical value is displayed on the display device 26 in accordance with an instruction. Display. When the terminal 20 receives an instruction to combine the first input display area and the second input display area, or the first calculation result display area and the second calculation result display area, the terminal 20 A first combined display in which the input display areas are combined and a second combined display in which the calculation result display areas are combined are displayed on the display device 26.

FIG. 20B is a diagram illustrating an example of operations and displays related to separation processing. The terminal 20 receives the separation operation instruction and generates separation information as described below.

The sticky notes to be operated in the separation process are a graph sticky note 103, a mathematical formula sticky note 104, a numerical table (mathematical formula) sticky note 106, and a statistical calculation sticky note 108. In order to separate a sticky note unit consisting of two or more sticky notes or a sticky note containing two or more separable contents into two sticky notes, the user must perform an operation to select and move the operation target (for example, by dragging) as a separation operation.・And-drop operation). If the position specified by the input device 25 when the separation operation starts is defined as the "separation operation start position", and the position specified by the input device 25 when the separation operation ends is defined as the "separation operation end position", then For example, the separation operation may be instructed when the separation operation end position exists outside the range where the sticky note that is the operation target of the separation process is displayed when the separation operation starts.

For example, in order to separate a sticky note unit in which two sticky notes are aligned and connected into two sticky notes, the user performs a separation operation by performing the separation operation on the tabs of one sticky note (the tabs 151 to 151 of the mathematical sticky note 104 and the statistical calculation sticky note 108). 154) and perform an operation (for example, a drag and drop operation) to select and move it. For example, in order to separate an integrated sticky note that includes two or more separable displays into two sticky notes, the user performs a separation operation on one sticky note's tabs (graph sticky note 103, number table (mathematical formula) sticky note 106). (112 to 117) and perform an operation (for example, a drag-and-drop operation) to move the selected tab.

The terminal 20 receives the separation operation instruction and displays the two sticky notes, which were displayed connected in a line, separated from each other (first separation process). Alternatively, the terminal 20 receives the separation operation instruction, creates a new sticky note based on the integrated sticky note, and adds the content associated with the tab to be operated to the newly created sticky note. (generates a copy of the displayed content to be separated) and hides it from the one sticky note that was displayed before the separation operation, and the one sticky note that was displayed before the separation operation has the target of the operation. Only the contents associated with tabs other than the tabs are displayed (second separation process). Alternatively, the terminal 20 receives the separation operation instruction, creates a new sticky note based on the integrated sticky note, and adds the content associated with the tab to be operated to the newly created sticky note. (generates a copy of the displayed content to be separated) and hides it from the one sticky note that was displayed before the separation operation, and the one sticky note that was displayed before the separation operation has that one The same content as that displayed before the separation operation is displayed on the sticky note (third separation process). Here, all of the above three types of separation processing are referred to as "separation". Other sticky notes linked to the sticky note to be manipulated are also separated. The coordinate value sticky notes and calculation sticky notes that are linked to the sticky note to be manipulated or to other sticky notes that are linked to the sticky note to be manipulated disappear.

The targets of the first separation process are the mathematical formula sticky note 104, the slider sticky note 105, the numerical table (mathematical formula) sticky note 106, and the statistical calculation sticky note 108. The mathematical formula sticky notes 104 and the slider sticky notes 106 shown in FIGS. 23A to 23C and FIGS. 28A to 28C, which will be described later, are display examples that have been subjected to the first separation process. Furthermore, the statistical calculation sticky notes 108 shown in FIGS. 34A to 34C are display examples that have been subjected to the second separation process. The target of the second separation process is the graph sticky note 103. Graph sticky notes 103 shown in FIGS. 23A to 23C, FIGS. 28A to 28C, and FIGS. 34A to 34C, which will be described later, are display examples that have been subjected to the second separation process. The target of the third separation process is the numerical table (statistics) sticky note 107. A numerical table (statistics) sticky note 107 shown in FIGS. 34A to 34C, which will be described later, is an example of a display that has been subjected to the third separation process.

In the present embodiment, the terminal 20 has a first input display area and a second input display area (mathematical sticky notes 104) in which functions are input and displayed and are displayed together, the first input display area and the A first main display (first graph) and the second input display area that are associated with the second input display area and are related to calculation results based on the function input to the first input display area. A calculation result display area (graph sticky note 103) in which a second main display (second graph) related to calculation results based on the function inputted in display. When the terminal 20 receives an instruction to separate the first input display area and the second input display area or an instruction to separate the first main display and the second main display, the terminal 20 The first input display area and the second input display area are displayed separately, the first main display is displayed in the first calculation result display area, and the second main display is displayed in the second calculation result display area. Display it in the result display area.

Instructions for creating and calculating the sticky notes 201 and 202 can be input and selected from various icons 80 displayed along with the input board 240 and the geometric sticky notes 203.

After the geometric figure is drawn on the geometric sticky note 203, measurement value sticky notes 201 and 202 can be created. When creating the measurement value sticky note 201, the user selects, for example, two points on a figure. Thereby, the terminal 20 receives an instruction to create the measurement value sticky note 201. If there is a measured value sticky note 201 associated with the geometric sticky note 203, the new measured value sticky note 201 is displayed below the existing measured value sticky note 201 (No. 21 in the table shown in FIG. 19). . This corresponds to, for example, creating the second measurement value sticky note 201b below the first measurement value sticky note 201a shown in FIG. In other cases, a new measurement value sticky note 201 associated with the geometric sticky note 203 is displayed (No. 22 in the table shown in FIG. 19). This corresponds to, for example, creating a new first measurement value sticky note 201a shown in FIG. 29.

When creating the calculation sticky note 202, the user selects the calculation icon 241. Thereby, the terminal 20 receives the instruction to create the calculation sticky note 202. If there is a calculation sticky note 202 associated with the geometry sticky note 203, the new calculation sticky note 202 is displayed connected to the bottom of the existing calculation sticky note 202 (No. 23 in the table shown in FIG. 19). In other cases, a new calculation sticky note 202 associated with the geometric sticky note 203 is displayed (No. 24 in the table shown in FIG. 19). This corresponds to, for example, creating the calculation sticky note 202 shown in FIG. 29.

In this way, the terminal 20 determines the display of the newly displayed sticky notes 201 and 202 depending on the presence or absence of the sticky notes 201 and 202 linked to the geometric sticky note 203. In particular, the measured value sticky note 201 and the calculation sticky note 202 exhibit behavior similar to the above-described coordinate value sticky note 109 and calculation (α+β) sticky note 110 in terms of creation.

Up to this point, we have explained that the statistical graph related to the statistical calculation results calculated by the server 10 is displayed on the graph sticky note 103, but depending on the type of statistical calculation being calculated, the statistical calculation result is only displayed on the statistical calculation sticky note 108. It can be done. FIG. 30 shows one such example.

FIG. 30 shows an example of a screen display when “One-Variable” is selected from the input board 140 for the numerical value input in column A of the numerical table 111 of the numerical table (statistics) sticky note 107. ing. By this selection, various information (for example, information on the numerical values in column A of the numerical table 111, information on the type of statistical calculation, etc.) is transmitted from the terminal 20 to the server 10, and the statistical calculation is executed by the server 10. The terminal 20 receives the statistical calculation results returned from the server 10. That is, the calculation process of step S18 in FIG. 3 is executed.

A statistical calculation sticky note 108 is created and displayed using the received statistical calculation results. At this time, the terminal 20 is executing the statistical calculation sticky note process in step S21 in FIG. The numerical table (statistics) sticky note 107 is tied to the statistical calculation sticky note 108 with a string 147. For example, No. in the table shown in FIG. 20, a statistical calculation sticky note 108 may be generated from the numerical table (statistics) sticky note 107.

FIG. 31 shows an example of a screen display when “Linear Regression” is selected from the input board 140 for the numerical values input in columns A and B of the numerical table 111 of the numerical table (statistics) sticky note 107. It is shown. With this selection, the calculation process of step S18 in FIG. 3 is executed, and further, a statistical graph showing the calculation result of Linear Regression is displayed by the graph sticky note process of step S19 and the statistical calculation sticky note process of step S21. A graph sticky note 103 indicating the statistical calculation result (character information) and a statistical calculation sticky note 108 indicating the statistical calculation result (character information) are created and displayed. The numerical table (statistics) sticky note 107 is tied to the graph sticky note 103 and the statistical calculation sticky note 108 with strings 146 and 147, respectively. For example, No. in the table shown in FIG. 4 and no. 20, a graph sticky note 103 and a statistical calculation sticky note 108 may be generated from the numerical table (statistics) sticky note 107.

For example, when the statistical calculation type is "One-Variable" or "Two-Variable," the server 10 performs the statistical calculation sticky note process in step S21 in FIG. 3, but does not perform the graph sticky note process in step S19. . Also, when the statistical calculation type is other than the above two types, for example, those related to statistical regression calculations such as "Linear Regression" and "Quadratic Regression", or "Scatter Plot", "Box & Whisker Plot", and "Histogram". , "Pie Chart", the statistical calculation sticky note process in step S21 and the graph sticky note process in step S19 in FIG. 3 are performed. In this way, whether or not the graph sticky note process in step S19 in FIG. 3 is performed differs depending on the statistical calculation type.

FIG. 32A is a diagram showing an example of a screen display consisting of a numerical table (statistics) sticky note 107 and a statistical calculation sticky note 108. In FIG. 32A, in the numerical table 111 of the numerical table (statistics) sticky note 107, the average temperature in March in Fukuoka is in the A column, the blooming date of cherry blossoms in Fukuoka (based on March 1st) in the B column, and the C column is the numerical table 111 of the numerical table (statistics) sticky note 107. The average temperature in March in Tokyo and the blooming date of cherry blossoms in Tokyo (based on March 1st) are entered in column D (both data from 1987 to 2004). The statistical calculation sticky note 108 displays the one-variable statistical calculation results for the values input in column A of the numerical table 111 of the numerical table (statistics) sticky note 107. For example, No. in the table shown in FIG. 20, a statistical calculation sticky note 108 may be generated from the numerical table (statistics) sticky note 107.

In FIG. 32B, the One-Variable statistical calculation result for the value input in column C of the numerical table of the numerical table (statistics) sticky note 107 is further displayed on the second statistical calculation sticky note 108b. The second statistical calculation sticky note 108b is displayed connected to the lower side of the first statistical calculation sticky note 108a. The transition from the display in FIG. 32A to the display in FIG. 32B is made by selecting No. 1 in the table shown in FIG. It corresponds to 19.

In this way, the statistical calculation sticky notes 108 linked to the numerical table (statistics) sticky notes 107 are displayed all at once, making it easy to view them at a glance.

FIG. 33A is an example of a screen display when Histogram statistical calculation is performed on column A of the numerical table 111 of the numerical table (statistics) sticky note 107 that is the same as that in FIG. 32A. A first statistical calculation sticky note 108a and a graph sticky note 103 linked to the numerical table (statistics) sticky note 107 are displayed.

FIG. 34B is an example of a screen display when Histogram statistical calculation is further performed on column C of the numerical table (statistics) sticky note 107. The second statistical calculation sticky note 108b is displayed connected to the lower side of the first statistical calculation sticky note 108a. The statistical graph is displayed superimposed on the graph sticky note 103.

In this way, by drawing the statistical graph overlappingly on one graph sticky note 103, it is easier to compare the two graphs. Further, the color of the tab 153a of the statistical calculation sticky note 108a is the same as the color of the corresponding tab 112 and the corresponding graph displayed on the graph sticky note 103, and the color of the tab 153b of the statistical calculation sticky note 108b and the color of the graph Since the colors of the corresponding tabs 113 and the corresponding graphs displayed on the sticky note 103 are the same, the statistical calculation range ("Data:A:A" or "Data:C") displayed on each statistical calculation sticky note 108a, 108b is the same. :C" display) and the numerical table (statistics) sticky note 107, you can see at a glance which data on the numerical table (statistics) sticky note 107 each graph displayed on the graph sticky note 103 corresponds to. You can see it.

FIG. 33C is an example of a screen display when Box & Whisker Plot statistical calculation is further performed on columns A and C of the numerical table 111 of the numerical table (statistics) sticky note 107. A third statistical calculation sticky note 108c is displayed connected to the bottom of the second statistical calculation sticky note 108b, and a fourth statistical calculation sticky note 108d is displayed connected to the bottom of the third statistical calculation sticky note 108c. has been done. The statistical graph is drawn on a graph sticky note 103. Four tabs 112, 113, 114, and 115 corresponding to statistical graphs are also displayed. The colors of the tab 153a of the statistical calculation sticky note 108a and the color of the tab 153c of the statistical calculation sticky note 108c, the colors of the corresponding tabs 112 and 114 displayed on the graph sticky note 103, and the colors of the corresponding graphs are the same, and Since the colors of the tab 153b of the calculation sticky note 108b and the color of the tab 153d of the statistical calculation sticky note 108d, the colors of the corresponding tabs 113 and 115 displayed on the graph sticky note 103, and the colors of the corresponding graphs are the same, the above effect is achieved. In addition, it can be seen at a glance that the plurality of graphs displayed on the graph sticky note 103 correspond to the same data on the numerical table (statistics) sticky note 107.

The separation and combination of sticky notes related to statistical calculation results will be explained below.
As shown in FIG. 34A, the user selects and moves the second tab 113 (eg, by drag and drop operation). As a result, as shown in FIG. 34B, the data (data of the second statistical graph) associated with the second tab 113 is displayed on the second graph sticky note 103b. Along with this, the corresponding second statistical calculation sticky note 108b is separated, and the second numerical table (statistics) sticky note 107b, in which a copy of column A of the numerical table 111 of the numerical table (statistics) sticky note 107 is generated, is separated. Is displayed. The numerical table (statistics) sticky note 107 is displayed as is as the first numerical table (statistics) sticky note 107a.

In the state shown in FIG. 34B, the user selects the fourth tab 115 and moves it so that it overlaps the second graph sticky note 103b (for example, by a drag and drop operation). As a result, as shown in FIG. 34C, data associated with the fourth tab 115 (data of the fourth statistical graph) is additionally displayed on the second graph sticky note 103b. Along with this, the corresponding statistical calculation sticky note 108b is separated, and a copy of column A of the numerical table of the first numerical table (statistics) sticky note 107a is generated and placed in the second numerical table (statistics) sticky note 107b as column B. Additional information will be displayed.

Figures 35A to 35C are an example of the screen display after executing Scatter Plot (Figure 35A) for the average temperature in March in Fukuoka and the blooming date of cherry blossoms, and the screen display after executing Linear Regression statistical calculation. An example (FIG. 35B) and an example of a screen display (FIG. 35C) after performing Scatter Plot and Linear Regression statistical calculations on the average temperature in March in Tokyo and the blooming date of cherry blossoms. The statistical calculation sticky notes 108a, 108b, 108c, and 108d are numbered in the table of FIG. It is created by connecting it to the bottom according to 19. In addition, the statistical graph is shown in No. 3 in the table of FIG. 3 is added to the graph sticky note 103.

Further, as shown in FIG. 35A, when only one graph is displayed on the graph sticky note 103, the tab of the graph sticky note 103 does not need to be displayed. As shown in FIGS. 35B and 35C, the tabs 112, 113, 114, and 115 of the graph sticky note 103 may be displayed only when two or more graphs are displayed on the graph sticky note 103. As a result, it can be determined whether only one graph is displayed on the graph sticky note 103 by simply checking whether or not the graph sticky note 103 has a tab. Further, just by looking at the number of tabs on the graph sticky note 103, it can be determined how many graphs are currently displayed on the graph sticky note 103.

In this embodiment, data displayed on each sticky note, which is a floating object, statistical calculation results, and statistical graphs can be arranged on one screen. It becomes possible to compare different types of statistical graphs, and it is possible to learn various analysis methods for the same data. Also, different types of statistical graphs can be combined into one graph sticky note or separated into separate graph sticky notes. This makes it possible to provide an easy-to-use display.

In particular, according to this embodiment, statistical graphs and statistical calculation results can be arranged and combined by easy operations such as drag and drop operations.

According to this embodiment, the graph drawing areas can be separated and combined, and the user can freely arrange formulas and graphs, thereby helping the user understand the properties of each graph and the relationships between graphs. In particular, when such a system is utilized in mathematics classes where ICT is increasingly used, it can help students understand functional graphs, statistical graphs, and statistical calculation results.
