FIG. 2 is a flowchart showing a graph display process executed by the graph display calculator 1.

In FIG. 2, first, when an operation mode switching is instructed by an input operation on the input unit 16, the CPU 11 reads out and executes the graph display program from the storage medium reading unit 14, and shifts to the graph mode (FIG. 2). Step S11).

Subsequently, the CPU 11 displays a data input screen 201 (FIG. 3A) on the screen of the display unit 18,
The state shifts to an input enabled state (step S12). Then, on the data input screen displayed on the screen of the display unit 18, data of the physical quantity to be represented by a graph is input by an operation on the input unit 16 or the tablet 20 (step S13).

Subsequently, a range in which a graph is to be displayed is input by an input operation on the input unit 16 or the tablet 20 (step S14), and further, an instruction is input for instructing display execution of an arrow graph based on the input data. (Step S15), the CPU 11 proceeds to step S1.
The display unit 1 displays an arrow graph reflecting the data input in step 3.
8 on the screen.

FIG. 3 is a view showing an example of a screen displayed on the display unit 18 in the graph display processing shown in FIG. 2, (a) showing a data input screen 201, and (b) showing data input. FIG. 3C shows a data input screen 201, and FIG.

The data input screen 201 shown in FIG.
Are provided with many data fields for inputting physical quantities to be displayed as a graph.

When data is input to the data input screen 201, the data is displayed in the data field as indicated by reference numeral 301 in the figure. Since a plurality of data fields are set on the data input screen 201, a plurality of data can be input.

The CPU 11 displays an arrow graph 302 on the graph display screen 202 based on the data input to the data input screen 201. For example,
In the graph display screen 202 shown in FIG. 3C, the width of the arrow graph 302 may indicate the physical quantity input on the data input screen 201. In this case, the larger the value of the input data is, the thicker the arrow graph 302 is displayed.

As described above, in the graph display processing shown in FIG. 2, the arrow graph 302 corresponding to the physical quantity input on the data input screen 201 can be displayed. That is,
Physical quantities can be quickly visualized, and in particular, in educational applications such as conventional scientific calculators, expressing quantities as planar figures is expected to have a high educational effect.

Next, the background protection display processing executed by the graph display control device 1 will be described. The background protection display processing shown in FIG. 4 is performed on a predetermined background image.
This is a process for displaying the arrow graph displayed in the graph display process.

In the processing shown in FIG.
When the switching of the operation mode is instructed by the input operation in 6, the CPU 11 reads out and executes the graph display program from the storage medium reading unit 14, and shifts to the graph mode (step S21).

Subsequently, the input unit 16 or the tablet 20
A world map is set as a background image by the operation in (step S22), and data for displaying an arrow graph is input (step S23). The data input here includes physical quantities and the like to be displayed as an arrow graph.

Then, the input unit 16 or the tablet 20
In step S24, when an input operation for instructing execution of arrow graph display is performed (step S24), the CPU 11 calculates the positions of the start point and the end point of the arrow graph to be displayed based on the data input in step S23. (Step S
25).

Next, the CPU 11 determines whether or not the background is set to protect the background at the time of setting the background at step S22 or at the time of data input at step S23 (step S26). If not, the flow shifts to step S32 to be described later, an arrow graph is displayed on the screen of the display unit 18, and this processing ends.

If the background is set to be protected (step S26; Yes), the CPU 11 determines whether or not there is a lit dot between the start point and the end point calculated in step S25. Determine (Step S2
7).

If there is a lighted dot between the start point and the end point calculated in step S25,
The CPU 11 acquires the information indicating the position of the corresponding dot and the lighting state, temporarily stores the information in the work area in the RAM 13, and secures the corresponding dot in the lighting state (step S28).

If it is determined in step S26 that the background is not protected,
If there is no lit dot in 27, the CPU 11 proceeds to step S32 described later.

After securing the corresponding dot in step S28, the CPU 11 changes the curvature of the arrow to be drawn between the starting point and the ending point calculated in step S25 so as not to overlap the secured dot ( Step S2
9).

Then, in step S29, the CPU 11 determines whether or not all the settable curvatures have been confirmed (step S30), and if not, returns to step S27.

Thereafter, the CPU 11 sets the curvature when the number of lit dots is the smallest as a result of variously changing the curvature of the arrow in step S29 (step S31).
That is, even when the arrow graph does not overlap with the reserved dot, the visibility becomes lower if the arrow graph becomes an abnormally large graph, so that the arrow graph does not overlap with the reserved dot, and is as large as possible. In step S31, a curvature with the smallest number of lit dots is set in order to display an arrow graph that does not work.

Then, the CPU 11 shifts to step S32, draws an arrow graph of the set curvature on the screen of the display unit 18, and ends this processing.

In the background protection display processing, the processing performed for the lit dots in steps S27, S28, and S31 may be performed for the unlit dots. That is,
The case where the above processing is performed on the lit dots is a case where a map or an arrow graph is lit on the screen of the display unit 18. That is, the dots on which no map or arrow graph is displayed are not lit. However,
In the case of the reverse display, dots other than the map and the arrow graph may be lit. In this case, in steps S27, S28, and S31, it is desirable to perform processing on dots that are not lit. Therefore, the flowchart shown in FIG. 4 illustrates both of the above cases.

FIG. 5 is a diagram showing an example of a screen displayed on the screen of the display unit 18 in the background protection display processing shown in FIG.
(A) shows a map display screen 203 on which a world map is displayed, and (b) shows a data input screen 201 in which data is input.
(C) shows the map display screen 203 on which the arrow graph 303 is displayed, and (d) shows the map display screen 203 on which the arrow graph 304 is displayed.

In step S22 in the background protection processing shown in FIG. 4, a world map is displayed on the screen of the display unit 18 as shown in FIG.

Then, as shown in FIG. 5B, on the data input screen 201, data relating to the arrow graph to be displayed on the map display screen 203 is input.

Thereafter, as shown in FIG. 5C, an arrow graph 303 is displayed on the map display screen 203 based on the data input on the data input screen 201. The arrow graph 303 is an arrow graph displayed when a process related to background protection is not performed.

Further, when a process for performing background protection is executed, an arrow graph 304 with a changed curvature is displayed on the map display screen 203 as shown in FIG. The arrow graph 304 is an arrow graph whose curvature is changed so that the map on the map display screen 203 is not hidden.

According to the background protection display processing described above, for example, by applying the learning application, learning using graph display can be introduced to various subjects, and a high learning effect can be expected.

Next, the on-map graph display processing executed by the graph display control device 1 will be described with reference to the flowchart of FIG.
