Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an XY coordinate display method. More specifically, the present invention relates to a method for displaying information selected from a plurality of information on a display such as a personal computer in XY coordinates.

[0002]

2. Description of the Related Art Conventionally, in the case of displaying information, for example, numerical data including sales of a company and the number of employees on an XY coordinate, on a display such as a personal computer, an operator first sets a coordinate area and then coordinates. It was necessary to enter the numerical value to be converted, and the minimum value, the maximum value, and the scale interval of the scale of each coordinate on the X axis (horizontal axis of company sales) and the Y axis (vertical axis of company employees). .

[0003]

Therefore, the operator must perform complicated input work before obtaining necessary information.
Moreover, it is very inconvenient because the coordinate scale must be calculated and set. In addition, the same work had to be repeated to capture new data, such as sales and employee numbers of other companies. Also X
Convert the axis and Y-axis, and take the number of employees of the company on the X-axis.
Combines various information such as taking the sales of the company on the axis, taking the sales of the company or the number of employees of the company on the X axis, and taking other numerical data (for example, the profit including tax of the company) on the Y axis. Displaying the coordinates was very time-consuming and troublesome.

Therefore, an object of the present invention is to provide an XY coordinate display method which eliminates the operator's complexity in the XY coordinate display and can display necessary information only by inputting a selection switch. is there.

Another object of the present invention is to provide an XY coordinate display method capable of making the coordinate display as a whole easy to see.

Still another object is to be able to practically use, for example, corporate information, although not limited to this.

[0007]

In order to achieve the above object, an XY coordinate display method of the present invention sets various data stored in a memory by setting an X axis and a Y axis orthogonal to each other on a display. In the XY coordinate display method of displaying coordinates, the maximum value of the coordinate scale is determined based on the maximum value of each numerical data element of at least two numerical data groups stored in the memory, and the maximum value of the coordinate scale is determined. After storing in the memory for each numerical data group, when the X-axis selection switch and the Y-axis selection switch provided corresponding to two or more numerical data groups are pressed, the numerical data selected by the X-axis selection switch The maximum value of the coordinate scale corresponding to the group is called from the memory, the coordinate scale of the X axis is updated with the position and size of the X axis unchanged, and the numerical data group selected by the Y axis selection switch. The maximum value of the corresponding coordinate scale is recalled from the memory, the Y-axis coordinate scale is updated with the Y-axis position and size unchanged, and the numerical data of the numerical data group selected for the updated XY coordinates is updated. The element is displayed in coordinates (claim 1).

Further, when a new numerical data element is stored in the memory, the numerical data element is compared with the maximum value of each numerical data element for each numerical data group stored in the memory, and each numerical data group is compared. If there is a numerical data element that is larger than the maximum value of each numerical data element, the numerical data element is further compared with the predetermined limit value, and if the numerical data element is less than or equal to the predetermined limit value, the numerical data element of the corresponding numerical data group is It is preferable to set the maximum value of the numerical data element, and if the numerical data element is larger than a predetermined limit value, display the numerical data element individually without displaying the XY coordinates (claim 2).

Further, it is preferable to determine the maximum value of the coordinate scale so that the maximum value of each numerical data element is set within the range of 70 to 100% of the maximum value of the coordinate scale (claim 3).

Further, the numerical data group includes at least a company information group showing a sales amount for each company, a company information group showing a profit including tax, and a company information group showing the number of employees (claim 4).

[0011]

According to the XY coordinate display method of the present invention, the maximum value of the coordinate scale is determined based on the maximum value of each numerical data element for each of at least two numerical data groups stored in advance in the memory, The maximum value of the coordinate scale is stored in the memory for each numerical data group. Then, when the X-axis selection switch and the Y-axis selection switch provided corresponding to two or more numerical data groups are pressed, the maximum value of the coordinate scale corresponding to each selected numerical data group is called from the memory. The coordinate scales of the axes and the Y-axis are updated, and the numerical data elements of the selected numerical data group are displayed on the updated X-Y coordinates while the positions and sizes of the X-axis and the Y-axis are unchanged. That is, the operator does not need to input the coordinate scale each time when the numerical data element is displayed as coordinates, and only has to press the X-axis selection switch and the Y-axis selection switch.

Preferably, it is judged whether or not the new numerical data element stored in the memory satisfies a condition of being larger than the maximum value of each numerical data element of each numerical data group and being equal to or less than a predetermined limit value, and the condition is satisfied. If is satisfied, the numerical data element is set as the maximum value of the numerical data elements of the corresponding numerical data group. That is, since the maximum value of the numerical data elements of the numerical data group can be automatically updated when a new numerical data element is input, when the operator subsequently presses the X-axis selection switch and the Y-axis selection switch, it is immediately updated. Numeric data elements are displayed on the XY coordinates of the appropriately updated coordinate scale. If the numerical data element is larger than a predetermined limit value, the numerical data element can be displayed individually without displaying the XY coordinates. Therefore, when each numerical data element is displayed in the XY coordinates, each numerical value is displayed. Data elements are unlikely to be concentrated at the bottom. More preferably,
Set the maximum value of each numerical data element to 70-of the maximum value of the coordinate scale.
Since the maximum value of the coordinate scale is determined so as to be set within the range of 100%, the possibility that each numerical data element is concentrated in the lower part when the XY coordinates are displayed is further reduced.

The selection switches 21A to 21C, 22A to 22C and the input switch 23 are selected by the operator pressing the mouse 7 on the screen or the corresponding key on the keyboard 6. A braid is formed on the selected switch.

In FIG. 2, the sales amount of the company is selected on the X axis, and the tax-included profit of the company is selected on the Y axis, and the corresponding numerical data of Kosha, Otosha, and Heisha are respectively ○,
The state is shown by the identification symbols of Δ and +. Although a CRT video display is used as the display 9 in this embodiment, an LCD or a gas plasma-based flat panel display may be used.

FIG. 3 shows an example of a memory map in the nonvolatile memory 4. In the area i of the memory, as corporate information,
Company name and address in CP _i area, company sales in A _i area (100 million yen), profit including tax in B _i area (1 million yen),
The number of employees (person) is stored in the C _i area. These data are input by the operator pressing the input switch 23 and then operating the keyboard 6. The maximum value of the sales amount of the company is stored in the MA area of the memory map, the maximum value of the tax-included profit of the company is stored in the MB area, and the maximum value of the number of employees of the company is stored in the MC area.
The maximum value of the coordinate scale obtained from the formulas described later based on the values of the MA, MB, and MC areas is stored in each of the SA, SB, and SC areas. Further, in the memory map, a predetermined identification symbol (○,
(△, +, etc.) are stored.

In FIG. 3, numerical data elements of Kosha, Otsusha, and Heisha, A ₁ = 523, B ₁ = 1521, C ₁
= 945, A ₂ = 306, B ₂ = 820, C ₂ = 720,
A ₃ = 201, B ₃ = 408, C ₃ = 206 are input,
MA calculated based on these numerical data elements, MA
= 523, MB = 1521, MC = 945, SA = 60
0, SB = 2000, SC = 1100 are stored.

Next, the processing contents of the CPU 1 will be described with reference to FIGS. As shown in FIG.
1 is initialized when the power is turned on (step 1;
"Hereinafter, the word step is omitted in parentheses.") At initialization, internal registers, counters, etc. are set to initial values. At this time, 1 is set in the register i indicating the memory area in the nonvolatile memory 4 as shown in FIG. Further, the data stored in the SA area of the memory map (FIG. 3) is set in the registers x ₀ and y ₀ indicating the maximum value of the coordinate scale of the X axis and the Y axis, and the register x indicating the value of the X coordinate and the Y coordinate. Numerical data elements stored in the A _i area are set in _i and y _i .

Then, the CPU 1 checks whether or not data is already stored in the memory area i (2), and increments the value of the register i by 1 every time there is data (3). As a result, the register i indicates the first area i in which no data is stored. Next, it is checked whether or not the input switch 23 for inputting new company information has been pressed (4). If not, whether or not any of the selection switches 21A to 21C for X-axis setting has been pressed. Check (5). When the X-axis selection switch is pressed, the X-axis coordinate scale determination process shown in FIG. 5 is performed (6). Next, it is checked whether any of the Y-axis setting selection switches 22A to 22C is pressed (7). When the Y-axis selection switch is pressed, the Y-axis coordinate scale determination shown in FIG. 6 is performed. Processing is performed (8).

The contents of the X-axis coordinate scale determination process (6) will be described below. The CPU 1 first checks which of the X-axis setting selection switches 21A to 21C has been pressed (61). If the pressed switch is the switch 21A, the data stored in the SA area is set in the register x ₀ indicating the maximum value of the X-axis coordinate scale, and A _i is set in the register x _i indicating the X coordinate value of the numerical data element. Set the data stored in the area (62, 6
3). The long been depressed switch is the switch 21B, sets the data stored in the SB area in register x _0, sets the numerical data elements stored in B _i region in the register x _i (64,65). Alternatively, if the pressed switch is the switch 21C, SC is set in the register x ₀ .
Sets the data stored in the area, C _i into register x _i
Set the numeric data element stored in the area (66,
67).

Next, each coordinate scale is determined from the data set in the register x ₀ (68). That is, x ₀ becomes X
Was determined as the maximum value of the coordinate scale axis, 1 times 10 divided value below _{x 0 (x 0/10)} , 2 -fold (2x _0/10),
3 times (3x _0/10), 4 times (4x _0/10), 5-fold (5
x _0/10), 6 times (6x _0/10), 7-fold (7x _0/1
0), eight times (8x _0/10), 9 times (9x _0/10), each coordinate scale of the X axis is determined by.

Similarly, with respect to the contents of the Y-axis coordinate scale determination process (8), the CPU 1 selects the Y-axis selection switch 22.
It is checked which switch of A to 22C is pressed (81), and the pressed switch is the switch 22.
If it is A, the register y ₀ showing the maximum value of the coordinate scale of the Y axis
Set the data stored in the SA area to
The numerical data element stored in the A _i area is set in the register y _i indicating the coordinate value (82, 83). If the pressed switch is the switch 22B, S is stored in the register y ₀ .
The data stored in the B area is set, and the numerical data element stored in the B _i area is set in the register y _i (8
4,85). Or the pressed switch is switch 2
If 2C, sets the data stored in the SC region register y _0, it sets the numerical data elements stored in the C _i region in the register y _i (86,87).

Next, each coordinate scale is determined from the data set in the register y ₀ (88). That is, y ₀ becomes Y
Was determined as the maximum value of the coordinate scale axis, 1 times 10 divided by the value of y ₀ less (y _0/10), 2-fold (2y _0/10),
3 times (3y _0/10), 4-fold (4y _0/10), 5-fold (5
y _0/10), 6-fold (6y _0/10), 7-fold (7y _0/1
0), 8-fold (8y _0/10), 9 times (9y _0/10), each coordinate scale of the Y axis is determined by. In this embodiment, the register x ₀ and the register y ₀ are each set to 10
Although the division is made, the number of divisions is not limited to this. Further, the degree of division may be changed according to the input company information.

Referring again to FIG. When the X-axis and Y-axis coordinate scales are determined, the coordinate scales are updated (9). At this time, the position and size (length) of the X axis and the Y axis are unchanged, and only the coordinate scale is updated. And shown in FIG.
The content of the data display process is performed (10). In the data display process (10), the CPU 1 first sets the register i in the register R.
After setting the value of, 1 is set in the register i (1
01, 102). The value of the register x _i indicating the X coordinate value of the numerical data element is less than or equal to the value of the register x ₀ indicating the maximum value of the coordinate scale of the X axis, and Y of the numerical data element.
It is checked whether or not the condition that the value of the register y _i indicating the coordinate value is equal to or less than the value of the register y ₀ indicating the maximum value of the coordinate scale of the Y axis is satisfied (103). Displays the coordinate data (x _i , y _i ) using the corresponding identification symbol (104). However, when the condition is not satisfied, the coordinate data (x _i , y _i ) is displayed outside the set XY coordinates, so that the coordinate data (x _i , y _i ) is individually displayed outside the XY coordinates (105).

Next, the value of the register i is incremented by 1 (106), until the value of i becomes larger than the value of the register R (107), the above steps 103-104.
Alternatively, step 105-step 106-step 1
07-Step 103 ... Is repeatedly performed.
As a result, the data of all companies stored in the memory map is displayed for the item selected by the X-axis selection switch and the Y-axis selection switch. here,
Although not shown, the displayed data may be output to the printer 11. When the X-axis selection switch and the Y-axis selection switch are not pressed, the data stored in the SA area is set in the registers x ₀ and y ₀ by the initialization in step 1, and the registers x _i and y _i are set to A _i.
Since the data stored in the area is set, the data related to the sales of all companies stored in the memory map is displayed. In this case, the coordinate items (sales of the company) and the coordinate scale are the same for both the X and Y axes, so Y =
The data will be displayed on the straight line of X. afterwards,
Return to step 4.

Referring again to FIG. When the input switch 23 is pressed in step 4, the data (company information company name / address, sales, profit including tax, number of employees) newly input by the operator is read and the data is stored in the area i (11, 12). Next, the numerical data element stored in the A _i area, that is, the sales of the newly input company is compared with the maximum value of the sales of the company stored in the MA area that has already been input (14), and is input. When the sales amount is larger than the maximum value of the existing sales amount, the input sales amount is further compared with the sales limit value LMA (in this embodiment, LMA is twice MA) (15). . Here, the limit value LMA of the sales amount is that when the input sales amount is larger than the already input sales amount and the value is evenly displayed in coordinates, the entire balance is lost and the already input sales amount is The value is concentrated in the lower part, making it difficult to see, so it is provided to prevent this.

Then, the input sales amount is the limit value LMA.
If the following is true, the SA determination process shown in FIG. 8 is performed (16). In the SA determination processing (16), the CPU 1 first updates the maximum value of the sales amount of the company stored in the MA area to the numerical data element stored in the A _i area (161),
The number of digits m of the numerical data element is detected (162). Then, the minimum value n ₀ of n (n is an integer) that satisfies the following equation, (MA / 0.9) ≦ (n × 10 ^m−1 ) (Equation 1) is calculated (n ₀ ×
The value of 10 ^m-1 ) is determined as the maximum value of the coordinate scale when the sales amount is taken as the coordinate axis, and this value is input to the SA area (163, 164). The reason that MA is divided by 0.9 in the above formula 1 is to display the maximum value of the sales near 90% of the maximum value of the coordinate scale to make it easy to see the data. The position is not particularly limited to 90%, but is preferably set within the range of 70% to 100%. This is because if it is less than 70%, the data may be concentrated in the lower part and may be difficult to see. If the input sales amount is larger than the limit value LMA, step 1 in FIG.
Since the condition of 03 is not satisfied, this numerical data element is X-
The Y coordinate is not displayed but is individually displayed in step 105.

For example, if the data of three companies (Ko, O, and Hei) are input as shown in the memory map of FIG. 3, the sales of Kosha is 523 (100 million yen) and the maximum sales is MA. It is stored in the area. Then, the expression 1 ((523 /
The minimum value n ₀ of n is calculated as 6 from 0.9) ≦ (n × 10 ^3-1 )), and the value of 600 = (6 × 10 ^3-1 ) is the coordinate when the sales amount is taken as the coordinate axis. S is determined as the maximum value of the scale
Stored in area A. And steps 61-62-63
As shown in −68 (FIG. 5), when the operator presses the X-axis setting selection switch 21A, for example, FIG.
X-axis coordinate scales 60, 120, 180, 24 shown in
0,300,360,420,480,540,600
Is determined.

Next, the numerical data element stored in the B _i area, that is, the tax-included profit of the newly input company is compared with the maximum value of the tax-included profit of the company stored in the already input MB area (17). If the input tax-included profit is larger than the maximum value of the existing tax-included profit, the input tax-included profit is further compared with the limit value LMB of the tax-included profit (LMB is twice the MB in this embodiment). (18). Limit value L of profit including tax
In case of MB, if the entered tax-included profit is more prominent than the already entered tax-included profit and the value is displayed evenly in coordinates, the whole balance is disturbed and the already-entered tax-included profit value becomes difficult to see. It is provided to prevent this.

Then, the input tax-included profit is the limit value LM.
If it is B or less, the SB determination process shown in FIG. 9 is performed (19). In the SB determination process (19), the CPU 1 first updates the maximum value of the profit including tax of the company stored in the MB area to the numerical data element stored in the B _i area (19).
1), the number of digits m of the numerical data element is detected (19
2). Then, the minimum value n ₀ of n (n is an integer) that satisfies the following equation, (MB / 0.9) ≦ (n × 10 ^m−1 ) (Equation 2) is calculated (n ₀ ×
The value of 10 ^m-1 ) is determined as the maximum value of the coordinate scale when the profit including tax is taken on the coordinate axis, and this value is input to the SB area (193, 194). The reason why MB is divided by 0.9 in Expression 2 is the same as the reason when MA in Expression 1 is divided by 0.9. The entered tax profit is the limit value LMB
If it is larger, the condition of step 103 in FIG. 7 is not satisfied, so that this numerical data element is individually displayed in step 105 without being displayed in XY coordinates.

For example, if the data of three companies (Ko, Otsu, Hei) are input (FIG. 3), Kosha's profit including tax is 15
21 (million yen) is stored in the MB area as the maximum value of profit including tax. Then, Expression 2 ((1521 / 0.9) ≦ (n
The minimum value n ₀ of n is calculated to be 2 from × 10 ^4-1 )), and 20
The value of 00 = (2 × 10 ^4-1 ) is determined as the maximum value of the coordinate scale when the profit including tax is taken on the coordinate axis, and is stored in the SB area. Then, as shown in steps 81-84-85-88 (FIG. 5), when the operator depresses the Y-axis setting selection switch 22B, for example, the Y-axis coordinate scales 200, 400, 600, shown in FIG. 800,100
0, 1200, 1400, 1600, 1800, 200
0 is determined.

Next, the numerical data element stored in the C _i area, that is, the number of employees of the newly input company is compared with the maximum value of the number of employees of the company already stored in the MC area (20). When the input number of employees is larger than the maximum value of the existing number of employees, the input number of employees is further compared with the limit value LMC of the number of employees (LMC is set to twice MC in this embodiment). (21). Limit number of employees L
In MC, if the number of input employees is more prominent than the number of already input and the value is evenly displayed on the coordinates evenly, the whole balance is disturbed and the value of the number of already input becomes difficult to see. It is provided to prevent this.

Then, the input number of employees is the limit value LM.
If it is C or less, the SC determination process shown in FIG. 10 is performed (22). In the SC determination process (22), the CPU 1 first sets the maximum value of the number of employees of the company stored in the MC area to C _i.
After updating to the numeric data elements stored in the area (22
1), the number of digits m of the numerical data element is detected (22
2). Then, the minimum value n ₀ of n (n is an integer) that satisfies the following equation, (MC / 0.9) ≦ (n × 10 ^m−1 ) (Equation 3) is calculated (n ₀ ×
The value of 10 ^m-1 ) is determined as the maximum value of the coordinate scale when the number of employees is taken as the coordinate axis, and this value is input to the SC area (223, 224). The reason why MC is divided by 0.9 in Expression 3 is the same as the reason when MA in Expression 1 is divided by 0.9. The number of employees entered is the limit value LMC
If it is larger, the condition of step 103 in FIG. 7 is not satisfied, so that this numerical data element is individually displayed in step 105 without being displayed in XY coordinates.

For example, if the data of three companies (Ko, O, and Hei) are input (FIG. 3), the number of employees of Kosha is 94.
5 (people) is stored in the MC area as the maximum value of the number of employees. Then, Expression 3 ((945 / 0.9) ≦ (n × 10
^3-1 )), the minimum value n ₀ of n is calculated to be 1100.
The value of (= 11 × 10 ^3-1 ) is determined as the maximum value of the coordinate scale when the number of employees is taken as the coordinate axis, and is stored in the SC area. When the operator presses the X-axis or Y-axis setting selection switch 21C or 22C, for example, X
Axis or Y-axis coordinate scales 110, 220, 330, 44
0,550,660,770,880,990,110
0 is determined.

Then, the value of the register i is incremented by 1 (23), the area i for storing the next input data is secured, and then the process returns to step 4.

In this embodiment, the example of displaying the company information of the three companies A, B, and Hei has been shown, but more companies can be displayed by adding the corresponding identification symbols. In addition, although three items of numerical data, sales, profit including tax, and number of employees are listed, sales / number of employees, profit including tax / number of employees may be displayed from these, or the past 5
By inputting numerical data for years, sales growth rate,
The profit growth rate including tax, the employee growth rate, the average sales growth rate, the average profit growth rate including tax, and the average employee growth rate may be displayed. It can also be used for a wide range of information, not limited to company information.

[0037]

As described above, according to the present invention, the operator is particularly required to display a desired numerical data element from the numerical data elements of at least two numerical data groups stored in the memory as coordinates. It is not necessary to input the coordinate scale each time while calculating it, and the coordinates can be displayed immediately by pressing the X-axis selection switch and the Y-axis selection switch, which is excellent in operability. For example, in the numerical data group, a company information group showing at least the sales of each company,
If the company information group showing the profit including tax and the company information group showing the number of employees are included, the company information can be compared immediately, which can be utilized for comprehensive company information management.

If the numerical data element is larger than a predetermined limit value, the numerical data element is individually displayed without being displayed in the XY coordinates. Therefore, when each numerical data element is displayed in the XY coordinates. It is unlikely that each numerical data element will be concentrated at the bottom. More preferably,
Set the maximum value of each numerical data element to 70-of the maximum value of the coordinate scale.
Since the maximum value of the coordinate scale is determined so as to be set within the range of 100%, the possibility that each numerical data element is concentrated in the lower part when the XY coordinates are displayed is further reduced. Therefore, it is possible to reduce the difficulty in viewing the coordinate display as a whole.

When the X-axis selection switch and the Y-axis selection switch provided in the memory are pressed, the maximum value of the coordinate scale corresponding to the numerical data group selected by the X-axis selection switch is called from the memory and X
With the position and size of the axis unchanged, the coordinate scale of the X-axis is updated, and the maximum value of the coordinate scale corresponding to the numerical data group selected by the Y-axis selection switch is called from the memory and the position and size of the Y-axis are updated. The XY coordinate display method is characterized in that the Y-axis coordinate scale is updated in a constant state, and the numerical data elements of the selected numerical data group are displayed as coordinates on the updated XY coordinates. 2. When a new numerical data element is stored in the memory, the numerical data element is compared with the maximum value of each numerical data element for each numerical data group stored in the memory to obtain numerical data. If there is a numerical data element that is larger than the maximum value of each numerical data element for each group, it is further compared with the specified limit value, and if that numerical data element is less than or equal to the specified limit value, that numerical data element is assigned the corresponding numerical data. The maximum value of the numerical data elements of the group, and when the numerical data element is larger than a predetermined limit value, the numerical data element is individually displayed without being displayed in the XY coordinates. XY coordinate display method. 3. The maximum value of the coordinate scale is determined so that the maximum value of each numerical data element is set within the range of 70% to 100% of the maximum value of the coordinate scale. Alternatively, the XY coordinate display method described in 2. 4. The numerical data group includes at least a company information group showing a sales amount of each company, a company information group showing a profit including tax,
4. The XY coordinate display method according to claim 1, further comprising a company information group indicating the number of employees.
