[0046]
Next, with reference to FIG. 3 and FIG. 4, the scroll bar control process in the first embodiment to which the present invention is applied will be described. FIG. 3 is an operation flow of the graph scientific calculator 1, and FIG. 4 is a diagram illustrating a transition example of screens displayed on the display unit 100.
[0047]
When the graph mode is instructed by the mode switching operation, the CPU 10 starts execution of a predetermined program related to the graph mode, sets the graph mode, and draws a graph such as an equation of a graph to be drawn and an input of a display range. It waits for input of such setting items. As shown in FIG. 3, when the CPU 10 detects a graph drawing input (step A10), the CPU 10 performs a graph drawing process in accordance with the input setting item (step A12).
[0048]
FIG. 4A shows an example of the graph display screen 600 displayed at this stage. As shown in the figure, a graph 602 based on the set display range is drawn on the graph display screen 600.
[0049]
Further, when the CPU 10 detects the execution input of the trace pointer function (step A14), the CPU 10 executes the trace pointer control program 202. First, as shown in FIG. While displaying (step A16), a scroll bar 606 is displayed at a predetermined position of the display unit 100 (step A18).
[0050]
In this embodiment, as shown in FIG. 4B, the coordinates of the trace pointer 604 are displayed on the coordinate display unit 608 together with the display of the trace pointer 604. The scroll bar 606 is the same as that conventionally known and corresponds to a predetermined coordinate axis. In the present embodiment, the scroll bar 606 corresponds to the x-axis, and has a bar portion 606a extending in the left-right direction and a scroll pointer 606b moving in the longitudinal direction on the bar portion 606a.
[0051]
Then, when detecting the movement operation of the pointer by the scroll bar (step A20), the CPU 10 calculates the position of the scroll pointer according to the movement operation amount and updates the display of the scroll pointer (step A22). Then, the CPU 10 executes the graphic rotation control program 204 and calculates the tangent line of the graph at the calculated scroll pointer position (step A24).
[0052]
Here, the CPU 10 calculates an angle formed by the tangent and the reference axis (step A26), and calculates a rotation matrix of a figure whose tangent matches the reference axis (step A28). Based on the rotation matrix, graph display data obtained by rotating the graph is calculated (step A30), and the updated graph display data is displayed on the graph display screen (step A32).
[0053]
For example, in the graph display screen 600 shown in FIG. 4B, when the scroll bar 606 is selected and dragged with the input pen, the trace pointer 604 of the graph display screen 600 moves as shown in FIG. 4C. The graph 602 is rotated and updated so that the tangent at the coordinates of the trace pointer 604 in the graph 602 is parallel to the x-axis. FIG. 4 shows the case where the x-axis is selected as the reference axis, but it goes without saying that the reference axis may be the y-axis or another straight line. FIG. 4D shows a display state of the graph 602 when the trace pointer 604 is further moved from FIG.
[0054]
Further, the CPU 10 monitors the function release input operation, accepts an input for re-execution of the pointer movement operation, and ends the process when determining that the function release input is detected (step A34: YES).
[0055]
As described above, according to the first embodiment, the trace pointer can be moved to a predetermined position on the graph drawn on the display screen by operating the scroll bar on the display screen. . Therefore, by operating the scroll bar so that the trace pointer continuously moves in the gazing interval of the graph, it is possible to more accurately understand the characteristics, outline, etc. in the gazing interval of the graph.
Since a scroll bar is displayed corresponding to a predetermined coordinate axis, the trace pointer on the graph can be moved with reference to the predetermined coordinate axis direction by operating the scroll bar in the predetermined coordinate axis direction. It is possible to grasp characteristics such as inclination and change amount in a predetermined coordinate axis direction.
In addition, the tangent direction of the graph at the display position of the trace pointer can be grasped. That is, when the trace pointer is continuously moved, the graph is also continuously rotated along with this, so that the characteristics such as the inclination of the gaze interval of the graph can be grasped more accurately.
[0056]
[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described. Note that the configuration of the graph scientific calculator in the second embodiment is the same as the configuration of the graph scientific calculator 1 shown in FIG. 2 in the first embodiment, but the ROM 20 is the ROM 21 and the RAM 40 shown in FIG. Is the same as the configuration in which the RAM 41 is replaced with the RAM 41 shown in FIG. 5B, and the same components are denoted by the same reference numerals and the description thereof is omitted.
[0057]
First, the configuration of the ROM 21 and the RAM 41 in the second embodiment to which the present invention is applied will be described with reference to FIG. FIG. 5A shows the configuration of the ROM 21, and FIG. 5B shows the configuration of the RAM 41. As shown in FIG. 5A, the ROM 21 stores a plurality of scroll bar control programs 212, in particular.
[0058]

[0059]
According to the second embodiment to which the present invention is applied, the function of a graph scientific calculator that moves the trace pointer by a plurality of scroll bars is realized. The CPU 10 executes processing according to the multiple scroll bar control program 212.
[0060]
Specifically, the CPU 10 displays a plurality of scroll bars, sets a movement range, a movement amount, and the like of the trace pointer for each scroll bar, and then newly displays one scroll bar. Then, the CPU 10 performs an operation process of the trace pointer based on the movement range, the movement amount, and the like that are already set by one scroll bar.
[0061]
Next, with reference to FIG. 6 and FIG. 7, the multiple scroll bar control process in the second embodiment to which the present invention is applied will be described. 6 shows an operation flow of the graph scientific calculator 1, and FIG. 7 shows a transition example of screens displayed on the display unit 100, respectively.
[0062]
When the graph mode is instructed by the mode switching operation, the CPU 10 starts execution of a predetermined program related to the graph mode, sets the graph mode, and draws a graph such as a mathematical expression of the graph to be drawn and an input of a display range. Wait for input of setting items. Then, as shown in FIG. 6, when the CPU 10 detects a graph drawing input (step B10), the CPU 10 performs a graph drawing process according to the input setting item (step B12).
[0063]
FIG. 7A shows an example of the graph display screen 610 displayed at this stage. As shown in the figure, a graph 612 based on the set display range is drawn on the graph display screen 610.
[0064]
When the CPU 10 detects the scroll bar drop function execution input (step B14), the CPU 10 starts to execute the plural scroll bar control program 212, and first displays that the function is executed on the graph display screen 610 (step B16). ). Thereafter, when the CPU 10 detects a scroll bar movement range and function designation operation (step B18), the CPU 10 secures the scroll bar function and movement range data (step B20).
[0065]
For example, as shown in FIG. 7B, when the first designation operation is performed, a first scroll bar 616 in a predetermined direction is displayed on the graph display screen 610. In this embodiment, as shown in FIG. 7B, the coordinates of the trace pointer 614 are displayed on the coordinate display unit 618 together with the display of the trace pointer 614. The first scroll bar 616 is similar to a conventionally known one, and has a bar portion 616a extending in the left-right direction and a scroll pointer 616b moving in the longitudinal direction on the bar portion 616a. In the present embodiment, both ends of the bar portion 616a of the first scroll bar 616 and both coordinates of the graph 612 corresponding to this moving range are temporarily displayed in a state connected by a broken line 616c. .
[0066]
For example, as shown in FIG. 7C, when the second designation operation is performed, in addition to the first scroll bar 616, a second scroll bar 617 in a predetermined direction is displayed. The second scroll bar 617 is similar to a conventionally known one, and includes a bar portion 617a extending in the left-right direction and a scroll pointer 617b moving in the longitudinal direction on the bar portion 617a. In the present embodiment, a state where both ends of the bar portion 617a of the first scroll bar 617 and the coordinates of the graph 612 corresponding to this movement range are connected by a broken line 617c is temporarily displayed. .
[0067]
Further, when the CPU 10 detects the operation of combining the plurality of scroll bars (step B22), the CPU 10 secures the functions and movement ranges of the plurality of scroll bars (step B24), and as shown in FIG. The display of the scroll bar 616 and the second scroll bar 617 is canceled, and a third scroll bar 619 extending in a predetermined direction of the graph display screen 610 is displayed. As shown in FIG. 7D, the third scroll bar 619 also has a bar portion 619a extending in the left-right direction and a scroll pointer 619b moving in the longitudinal direction on the bar portion 619a.
[0068]
In this state, when the CPU 10 detects a scroll bar operation execution input (step B26), the CPU 10 calculates the amount of movement of the scroll bar (step B28), updates the scroll bar display data based on this amount of movement, and displays the graph. It is displayed on the screen 610 (step B30). Further, the CPU 10 calculates operation data of the function associated with the scroll bar (step B32). In the present embodiment, this operation data includes the coordinates of the trace pointer on the graph 612 operated by moving the scroll bar.
[0069]
Next, the CPU 10 determines whether or not the coordinates of the trace pointer are outside the movement range secured in step B24 (step B34). If the coordinates of the trace pointer are outside the movement range, the related function data is recalculated (step B36), and the related function data is displayed and updated (step B38). Specifically, the coordinates of the trace pointer are recalculated so as to be the critical coordinates of the operation range in the graph, and the trace pointer 614 is displayed and updated at the position of the critical coordinates as shown in FIG.
[0070]
In step B34, if the coordinates of the trace pointer are within the movement range, the trace pointer 614 is updated on the graph 612 based on the coordinates as shown in FIGS. 7 (e) and 7 (g). (Step B38).
[0071]
Further, the CPU 10 monitors the end input operation, accepts an input for re-execution of the pointer movement operation, and ends the process when determining that the end input is detected (step B40: YES).
[0072]
As described above, according to the second embodiment, since a plurality of scroll bars are displayed, the movement range and movement amount of the trace pointer can be set for each scroll bar. Therefore, even when there are a plurality of gazing intervals in the graph or when there are a plurality of parameters to be gazed on the graph, the properties of the desired graph can be separately grasped by each scroll bar.
In addition, since the functions of the plurality of scroll bars are combined to generate one new scroll bar, it is possible to perform a process of moving the trace pointer by the plurality of scroll bars by operating one scroll bar.
[0073]
