FIG. 5 is a diagram showing a trace display operation (part 1) accompanying the pie chart trace display processing of the electronic computer.

FIG. 6 is a diagram showing a trace display operation (part 2) accompanying the pie chart trace display processing of the electronic computer.

As shown in FIG. 5A, a "pie graph" key 12d in the key input section 12 is used to graph and analyze the ratio (ratio) of each data to the whole of the inputted statistical data. Is operated, the statistical data A (1000), B (300), C (50), and D (50) stored in the statistical data memory 16b in the RAM 16 are operated.
0) and E (200) are arranged and displayed at the left end of the display screen of the liquid crystal display unit 18, and a ratio (ratio) corresponding to each value of each data included in the statistical data.
Is displayed as a pie chart divided into fan-shaped areas with the entire circumference taken as 100.

When the statistical data is displayed in the form of a pie chart and the "trace" key 12e of the key input unit 12 is operated as shown in FIG. The process is started, and the first data A (1000) of the statistical data graphed by the pie chart is stored in the trace target data memory 16d.
And the first data A (1000) as the data to be traced is highlighted and the process proceeds to the trace filling process in FIG. 4 (steps S1, S2, SA).

When the trace filling process is started, first, the minimum radius corresponding to the minimum reverse filling region set in advance with respect to the center of the pie graph is stored in the trace radius data memory 16e in the RAM 14. Is converted to the number of display dots and set.
A region corresponding to the minimum radius set in the radius data memory 16e overlaps a predetermined region or more with the fan-shaped graph region corresponding to the first data A (1000) set in the trace target data memory 16d. It is determined whether or not the trace display can be identified by the reverse filling (steps A1 and A1).
2).

In this case, the first data, which is the data to be traced,
The area corresponding to the minimum radius set in the trace radius data memory 16e overlaps by more than a predetermined area in the sector graph area of the data A (1000), and the graph area of the first data A (1000) is displayed in a trace. Since it is determined that the fill by inversion for indicating as is possible, the first data A (10
In the graph area of (00), the area of the portion overlapping the minimum radius is filled by inversion, and the first data A
(Step A)
2 → A3).

In this case, not the entire fan-shaped graph area corresponding to the first data A is filled by inversion, but only the overlapping area corresponding to the minimum radius is filled. Can do it.

Thus, after the graph trace display TA of the area corresponding to the first data A is performed,
As shown in FIG. 5C, when the "trace" key 12e in the key input unit 12 is operated, the trace display processing of the pie chart in FIG. 3 is started again, and the pie chart is graphed. The second data B (300) of the statistical data is set in the trace target data memory 16d, and the second data B (300) as the trace target data is displayed in reverse video, and the trace fill processing in FIG. Migrated (step S
1, S2, SA).

Then, when this trace filling process is restarted, the trace radius data memory 16e in the RAM 14 is referred to the center of the pie graph in the same manner as the filling process for the first data A (1000). Is set as the minimum radius data corresponding to the minimum reverse fill area set in advance as the second data B set in the trace target data memory 16d.
It is determined whether or not a region corresponding to the minimum radius set in the radius data memory 16e overlaps by a predetermined region or more with respect to the fan-shaped graph region corresponding to (300), and it is possible to identify the trace display by reverse painting. It is determined whether there is (Steps A1 and A2).

Also in this case, the area corresponding to the minimum radius set in the trace radius data memory 16e overlaps by a predetermined area or more in the sector graph area of the second data B (300) which is the data to be traced. Since it is determined that the fill by inversion for indicating the graph area of the second data B (300) as a trace display is possible, the second data B (30) as a trace target is determined.
In the graph area of (0), the area of the portion overlapping the minimum radius is painted out by inversion and shown as a graph trace display TB of the second data B (step A2).
→ A3).

In this case as well, the entire fan-shaped graph area corresponding to the second data B is not filled by inversion, but only the area overlapping the minimum radius is filled. Can be performed.

Further, after this, the "trace" key 12e
Is operated, as shown in FIG. 5 (D), the third data which is relatively small value data in the statistical data.
When the process shifts to the filling process (see FIG. 4) for the trace display process for the data C (50), the sector radius graph area of the third data C (50) which is the data to be traced has the trace radius data memory. The region corresponding to the minimum radius set in 16e does not overlap by more than a predetermined region, and it is determined that the filling by inversion for indicating the graph region of the third data C (50) as a trace display is impossible. Then, the trace radius data memory 1
The minimum radius data set in 6e is enlarged and updated one dot point at a time, up to the maximum radius of the pie graph, and each time the minimum radius data is set to the narrow fan-shaped graph area corresponding to the third data C (50). It is determined whether or not the area corresponding to the enlarged and updated radius overlaps by a predetermined area or more, and it is determined whether or not the trace display can be identified by the reverse filling (steps A1, A2 → A4 → A).
5 → A2).

Then, the trace radius data memory 1
When the radius data set in 6e is enlarged and updated to a certain value, even in the narrow sector graph area of the third data C (50) that is the trace target data, an area corresponding to the enlarged and updated radius Are overlapped by more than a predetermined area, and if it is determined that a fill by inversion for indicating the graph area of the third data C (50) as a trace display is possible, the graph area of the third data C (50) In the graph, the area of the portion overlapping the radius enlarged and updated in the trace radius data memory 16e is painted out by inversion, and the graph trace display TC of the third data C is displayed.
(Step A2 → A3).

When the "trace" key 12e is further operated thereafter, as shown in FIG. 5E, the fourth data D (500) in the statistical data is used as the data to be traced in the RAM 16 as the data to be traced. Memory 16d
After the numerical value is inverted and displayed on the liquid crystal display unit 18 (steps S1, S2, SA), the process proceeds to the trace filling process in FIG. 4, where the first data A (1000) and the second As in the trace filling process for the data B (300), steps A1, A
After processing 2 → A3, the trace radius data memory 16
The graph trace display TD is performed by inverting the area corresponding to the minimum radius set in e.

On the other hand, as shown in FIG. 6, the statistical data stored in the statistical data memory 16b in the RAM 16 is, for example, A (1000), B (300), C (1),
D (500) and E (200), and when the third data C (1) has an extremely small value as compared with the other data, as shown in FIG. When the pie chart corresponding to the statistical data is drawn and displayed in response to the operation of the "graph" key 12d, the third data C
The graph area corresponding to (1) cannot be sufficiently secured, and the graph area of the adjacent second data B (300) and the graph area of the fourth data D (500) cannot be distinguished from each other. There is no state.

As described above, in the display state of the pie chart including the third data C (1) which is extremely small compared to other data in the statistical data, FIG.
→ As shown in FIG. 6C, the graph trace display TA corresponding to the first data A (1000) and the second data B (300) are operated in response to the operation of the "trace" key 12e in the key input unit 12. ) Correspond to step S in FIG.
1, S2, SA, steps A1, A2 → A in FIG.
3 and then a “trace” key 1
As shown in FIG. 6 (D), when the operation is shifted to the painting process (see FIG. 4) for the trace display process for the third data C (1) by operating the 2e, the trace target data In the linear graph area of the third data C (1), the trace radius data memory 16
Since the area corresponding to the minimum radius set in e does not overlap by more than the predetermined area, it is determined that the filling by inversion for indicating the graph area of the third data C (1) as a trace display is impossible. (Steps A1, A
2).

Then, the trace radius data memory 1
The minimum radius data set in 6e is enlarged and updated one dot point at a time, up to the maximum radius of the pie graph, and each time, the linear graph area corresponding to the third data C (1) is updated. Then, it is determined whether or not the area corresponding to the enlarged and updated radius overlaps by a predetermined area or more, and it is determined whether or not the trace display can be identified by the reverse filling (step A2 → A4 → A5 → A2).

In this case, even if the radius data set in the trace radius data memory 16e is enlarged and updated until the radius data reaches the maximum radius of the pie chart, the linear data of the third data C (1) which is the data to be traced is obtained. The graph area of
The region corresponding to the maximum radius does not overlap by more than a predetermined region, and it is determined that the filling by inversion for indicating the graph region of the third data C (1) as a trace display is impossible. For the graph area of data C (1) of No. 3, graph trace display TC is performed by a pointer (steps A2 → A4 → A6).

Therefore, according to the graph display function of the electronic computing device having the above-described configuration, statistical data obtained by collecting a plurality of classification data is input, and a pie chart corresponding to the statistical data is drawn and displayed (FIG. 6 ( A)), when the "trace" key 12e is operated, each time the "trace" key 12e is operated, the individual data values A (1000), B (300),. The data is sequentially displayed in reverse as data, and the graph trace displays TA, TB,
(See FIGS. 6B and 6C). For data C (1) in which the proportion of the data value in the statistical data is extremely small and a filled area for trace display on a pie chart cannot be secured, the data C
Since the graph trace display TC by pointer display is performed corresponding to the graph position corresponding to (1) (FIG. 6)
(See (D)), which data in the statistical data is to be traced can be clearly confirmed by the reverse display of the data value, and on the pie graph, a graph area corresponding to each data is displayed in the pie graph. Regardless of the ratio of the occupation ratio, a clear graph trace display can be performed by the reverse filling display and the pointer display corresponding to each graph region.

Further, according to the graph display function of the electronic computer having the above-described configuration, when performing trace display of the graph area corresponding to each data in the statistical data on the pie chart, inversion display of each graph area is performed. (See FIGS. 5 and 6), the center of a pie chart that can be identified by the filled display, instead of performing the inverted filled display over the entire range of each area. Graph trace display TA, TB by reverse fill display only in the area where each graph area overlaps with the area corresponding to the minimum radius from
,..., And the ratio of data values to be traced is relatively small, and the corresponding graph region is narrow, so that the range overlapping with the region corresponding to the minimum radius from the center of the pie graph is a predetermined region. In addition, if it is determined that the identification by the fill display is difficult (see FIG. 5D), the minimum radius from the center of the pie graph, which is the reference for setting the fill area, is determined by the graph to be traced. Since the area overlapping with the area is enlarged and updated until the area becomes equal to or larger than the predetermined area, and the area corresponding to the enlarged set radius is subjected to the graph trace display TC by the reverse fill display, the reverse fill for each data area of the pie chart is performed. Graph trace display by display TA, TB
, TC,... Can be performed quickly and clearly.

In the above-described embodiment, a graph area in which the ratio of the data value in the statistical data is extremely small and a filled area for the trace display on the pie chart cannot be ensured corresponds to the graph position. In this case, the graph area of the data to be traced is clearly displayed by performing the graph trace display TC by pointer display (see FIG. 6D). For regions,
As shown in FIG. 7, a clear graph trace display TC may be performed by enlarging the corresponding graph area.

FIG. 7 is a diagram showing a trace display operation by enlarging and displaying a trace target graph area accompanying the pie chart trace display processing of the electronic computer.

Further, in the above-described embodiment, a case has been described in which statistical data is displayed as an image as a pie chart, and trace display of a graph area corresponding to each data is performed on the pie chart. However, as shown in FIG. Even when the same statistical data is displayed as a bar graph as an image and trace display of a graph area corresponding to each data is performed on the bar graph, trace display processing (TA, TB) by reverse filling display similar to the above embodiment, Trace display processing (TC) by pointer display can be performed.

FIG. 8 is a diagram showing a trace display operation associated with the bar graph trace display processing of the electronic computer.

Further, in the trace display processing by the reverse filling display and the trace display processing by the pointer display performed in each of the above-described embodiments, the liquid crystal display section 18 is a color display, so that a more clear trace display can be made by color-coded display. A configuration may be adopted.

The techniques described in the above embodiment, that is, the pie chart trace display processing shown in the flowchart of FIG. 3 and the paint processing associated with the trace display processing shown in the flowchart of FIG. As a program that can be executed by a computer, a memory card (ROM card, RAM card, etc.),
It can be stored and distributed on an external recording medium 14 such as a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a semiconductor memory or the like. Then, the computer operates the external recording medium 1
4 is read by a recording medium reading unit 15 such as a magnetic disk device, and the operation is controlled by the read program, thereby realizing the graph tracing function described in the above-described embodiment. Similar graph trace processing can be executed.

[0063]

As described above, according to the graph display device of the first aspect of the present invention, each time a trace for the displayed graph is instructed, each data value displayed as the graph is corresponded. It is sequentially determined whether or not each of the graph regions is equal to or larger than a predetermined region. A trace display by filling is performed on the graph region determined to be equal to or larger than the predetermined region, and for a graph region determined to be not equal to or larger than the predetermined region. Is traced by a pointer indicating the position of the graph area, so that the graph area corresponding to each data value on, for example, a pie chart or a bar graph is clearly traced regardless of the proportion of the graph area. It can be displayed.

According to the graph display device of the second aspect of the present invention, the range of the fill for the graph area determined to be equal to or larger than the predetermined area is determined based on a predetermined partial range. Is changed to a larger range as the graph becomes narrower. Instead of performing the fill display over the entire range of each graph region, the fill display is performed in the minimum range that can be identified as a trace display. Trace display by filling can be performed quickly and clearly.

According to the graph display device of the third aspect of the present invention, a plurality of data values input by the data input means are displayed in an array, and each time a trace for the graph is instructed, Since the data value to be traced among the plurality of displayed data values is identified and displayed, it is possible to clearly confirm which data value is to be traced.

Therefore, according to the present invention, in the display of a pie chart, a bar graph, or the like divided by an area having a width corresponding to the value of each data, small data in which the width of the graph cannot be sufficiently secured are mixed. Even when the display is performed, a clear graph trace display can be performed. Further, even when a region corresponding to each data is displayed in reverse video and a graph trace is performed, a quick graph trace display can be performed.
