  Next, the operation of the electronic computer 10 having the above configuration will be described.

  Note that the processes shown in the following flowcharts are executed when the CPU 11, which is a computer, reads the graph display control program 14 a stored in the storage device 14.

  FIG. 6 is a flowchart showing the overall flow of the graph display process in the statistical calculation mode executed by the CPU 11 provided in the electronic computer 10.

  FIG. 7 is a flowchart showing color-coded histogram generation processing accompanying the graph display processing in the statistical calculation mode in the electronic computer 10.

(Data input)
FIG. 8 is a diagram showing an example of a list input screen associated with a graph display process in the statistical calculation mode in the electronic computer 10.

  First, when the user operates the “Menu” key 12 c provided on the key input unit 12 of the electronic computer 10 to set the statistical calculation mode, the list input as shown in FIG. 8 is performed on the display unit 13 under the control of the CPU 11. A screen 21 is displayed (step A1).

  As shown in FIG. 8, the list input screen 21 is provided with a list (table) 22 composed of a plurality of cells. When the user operates the numerical value / symbol key 12a of the key input unit 12 to input numerical data into each cell of the list 22, list data (statistical data) including these numerical data is created (step) A2).

  At this time, when the “Color” key 12 e provided in the key input unit 12 is operated, a selection menu of red (Red), blue (Blue), green (Grn), and yellow (Yllw) is displayed at the lower end of the list input screen 21. 23 is displayed, and an arbitrary color can be designated for each numerical value by operating the function key “Fn” corresponding to each color of the selection menu 23.

  Here, it is assumed that the function key “F2” is operated in red, the function key “F3” is operated in blue, the function key “F4” is operated in green, and the function key “F5” is operated in yellow.

  In the example of FIG. 8, the numeric data “10” input to the first cell of List1 is red for the numeric data “10” input to the second cell, the black is input to the numeric data “9” input to the second cell, and is input to the third cell. Red is designated for the numerical data “11” and blue is designated for the numerical data “13” input to the fourth cell.

  The hatching attached to each numerical data represents a designated color. These hatchings are given for convenience because they cannot be expressed by coloring due to restrictions in the drawing, and numerical data is actually displayed in color with a specified color.

  In this way, when an arbitrary color is designated for each numerical data of the list data (Yes in step A3), the designated color is set as the attribute information in the numerical data and stored in the list data in the RAM 15. It is stored in the area 15c (step A4).

  If no color is specified, black is assumed to be the default color for the numerical data.

(Graph display based on list data)
After the creation of the list data, when the “Graph” key 12f provided in the key input unit 12 is operated, a graph type selection menu (not shown) showing graph types such as “Scatter”, “Histgram”, and “Regression graph” ) Are displayed along the bottom of the screen, and an arbitrary graph type can be selected by operating the function key “Fn”.

  Here, when “Histgram” is selected (Yes in Step A5), the process proceeds to the color-coded histogram generation process in FIG. 7 (Step AB).

  FIG. 9 is a diagram showing a specific example of the color-specific list 15 dc for each class range of the list data temporarily stored in the RAM 15 in accordance with the color-coded histogram generation processing of the electronic computer 10.

  FIG. 10 is a diagram showing a specific example of the graph display screen 31 of the histogram 32 generated in accordance with the color-coded histogram generation processing of the electronic computer 10.

  The histogram 32 includes a plurality of columnar graphs 32a, 32b, 32c,... In which numerical data is accumulated for each class. The cumulative results of numerical data for each class can be compared from the heights of these columnar graphs 32a, 32b, 32c,.

  The example of FIG. 10 corresponds to the list data (15c) shown in FIG. 3 and FIG. 8 and the class range data (15d) shown in FIG. 4, and according to the specified color specified for each numerical data. Each columnar graph 35a, 35b, 35c,... Is displayed in color.

  That is, when the process proceeds to the color-coded histogram generation process, first, the first class range (small section) [0 to 10 (less than)] stored in the class range data storage area 15d is read (step B1).

  Then, the list data stored in the list data storage area 15c is read (step B2), and the number of data (frequency) of the numerical data within the first class range is counted for each color specified in the numerical data. Then, as shown in FIG. 9, it is temporarily stored in the RAM 15 as a color range list 15dc for each class range (step B3).

  In the specific example of FIG. 9, the number of data (frequency) of the numerical data in the first class range [0 to 10 (less than)] is counted as black.

  Here, it is judged whether the same color is designated for all the numerical data counted corresponding to the first class range, that is, whether it is counted as the number of data of only one color (step B4). The designated colors of the numerical data in the range are all determined to be the same color (black) (Yes in step B4).

  Then, a histogram columnar graph 32a represented by the specified color (black) of the numerical data in the first class range is generated and stored in the graph data storage area 15e of the RAM 15 (step B5).

  Here, it is determined whether or not the processing for all the class ranges stored in the class range data storage area 15d has been completed (step B7). If it is determined that the process has not been completed (No in step B7), The next class, that is, the second class range (small section) [10 to 20 (less than)] is read (step B8), and the process returns to step B2.

  In the specific example of FIG. 9, the number of data (frequency) in the second class range [10 to 20 (less than)] is counted as 9 for red and 1 for blue (steps B2 and B3). ), It is determined that the designated colors of the numerical data in the second class range are not the same color (No in step B4).

  Then, a histogram representing the second class range including numerical data that is not the same color is generated as a columnar graph 32b having a special mode (black stripe pattern) and stored in the graph data storage area 15d of the RAM 15 (step B6). ).

  Thereafter, as described above, the processing for the next class range is repeatedly executed to generate the corresponding color or special mode columnar graphs 32c, 32d,..., 32k, which are stored in the graph data storage area 15d of the RAM 15. (Steps B2 to B8).

  When it is determined that the processing for all the class ranges has been completed (Yes in Step B7), the series of color-coded histogram generation processing returns to the graph display processing in the statistical calculation mode (Return).

  The histogram 32 stored in the graph data storage area 15e is developed in the display data storage area 15a and displayed in color on the screen of the display unit 13 as a graph display screen 31 as shown in FIG. 10 (step A6). .

(Color change after graph display)
Here, after the display of the graph, when the “Color” key 12e provided in the key input unit 12 is operated by the user (Yes in Step A7), red is displayed at the lower end of the graph display screen 31 (Red). A selection menu 23 of blue, blue, green (Grn), and yellow (Yllw) is displayed.

  When one color in the selection menu 23 is designated by operating the function key “Fn” (Yes in Step A8), the color of the entire graph is changed to the designated color (Step A9). Accordingly, the color designated for each numerical data of the list data stored in the list data storage area 15c of the RAM 15 is similarly changed (step A10).

  For example, when the “Color” key 12e is operated in a state where the histogram 32 as shown in FIG. 10 is displayed, the selection menu 23 is displayed at the lower end of the screen, and the blue color ( If “Blue” is designated by the operation of the function key “Fn”, all the columnar graphs 32 a to 32 k constituting the histogram 32 are changed to blue.

  All the colors designated for the numerical data of the list data corresponding to the histogram 32 are also changed to blue.

  The same applies to the graphs corresponding to “Scatter” and “Regression graph”, and the color of these graphs is changed to the color specified in the selection menu 23, and all numerical data of the list data for which the color change is targeted The color will be reflected in the same way.

-Partial change On the other hand, after the "Color" key 12e is operated (Yes in Step A7), when the "Trace" key 12g is operated instead of the function key "Fn" (Step A11), the graph display screen 31 A selection menu 23 of red (Red), blue (Blue), green (Grn), and yellow (Yllw) is displayed at the lower end, and partial color change is performed in the following procedure.

  Since the electronic computer 10 is not provided with a touch panel, when switching to the trace mode by operating the “Trace” key 12g, the object being displayed by the operation of the cursor key 12i (for example, each columnar shape of the histogram 32). It is assumed that an operation of designating the graphs 32a, 32b,.

  Here, when the “Trace” key 12g is operated (Yes in Step A11), if the currently displayed graph type is a histogram (Yes in Step A12), the object selected by operating the cursor key 12i (Yes in Step A12) Columnar graph) is extracted as a color change target, and is identified and displayed by blinking or the like (step A13).

  When one color in the selection menu 23 is designated by the operation of the function key (Yes in Step A14), the color of the extracted object (column graph) is changed to the designated color (Step A15). Accordingly, the designated color of each numerical data included in the corresponding class range of the list data stored in the list data storage area 15c of the RAM 15 is also changed (step A16).

  For example, in the graph display screen 31 of “Histgram” shown in FIG. 10, if the columnar graph 35 b is selected as a color change target (object), and red (Red) in the selection menu 23 is designated, the columnar graph Only 35b is changed from the striped pattern of the special mode to red.

  At this time, all the colors designated for the numerical data of the list data included in the class range corresponding to the columnar graph 35b of the histogram 32 are also unified and changed to red.

  Similarly, the color of the designated object can be partially changed while designating the object one by one by operating the cursor key 12i.

  Here, when the “EXIT” key 12h provided in the key input unit 12 is operated (Yes in step A17), the graph display state is exited, and the list data corresponding to the graph is stored from the list data storage area 15c of the RAM 15. It is read out and displayed on the screen (step A18). At this time, if there is a color change in the graph, the color of the displayed list data also changes.

  Therefore, according to the graph display function in the statistical calculation mode in the electronic computer 10 having the above-described configuration, when the user inputs list data, an arbitrary color corresponding to the class range is designated for each numerical data of the list data. As a result, a histogram composed of columnar graphs for each class according to the designated color is displayed in color. At this time, if the specified colors of the numerical data in a certain class range are not the same but are specified differently, the columnar graph corresponding to the same class range is displayed in color in a special form such as a striped pattern. For this reason, the mutual relationship between the list data and the histogram can be visually grasped by the color and the display mode, and the characteristics of the histogram drawn based on the list data can be easily understood.

  Furthermore, if the user changes the color of the displayed histogram in whole or in part, the color change is reflected in the numerical data of the list data. You can easily learn the interrelationship with the color change.
