Abstract

PURPOSE:To grasp the correlation between a graph output and its basic source data, by generating a table pattern in accordance with inputted information and a graphic pattern corresponding to the table pattern and displaying them on the same screen. CONSTITUTION:A keyboard 1 is used for inputting data and commands into a microprocessor 2. The microprocessor 2 is provided with a table implementing means 3 which generates and processes a table pattern and a graph generating means which generates and processes a graph pattern and each pattern is outputted to a CRT display section. The means 3 and 4 discriminate information inputted through keys and, when information is a command for selecting the kind of tables, the means 4 is weakened in power and a table pattern is generated. When table data are inputted, a table in which numerical data are arranged in the table pattern is displayed in a divided area of a screen 10. When the command for selecting the kind of tables is discriminated, the means 4 calls up a code list which generates a graph pattern. The code list is composed of a confirmed part consisting the graph and unconfirmed part which governs the size of picture elements, and the unconfirmed part is confirmed when table data are inputted.

Description

[Detailed description of the invention] Technical field The present invention relates to a graph processing device.

BACKGROUND ART Conventionally, processing devices dedicated to graphs have appealed to the visual sense only by expressing graphs that are easy to read. Also,
If necessary, the size of each pixel in the display graph is also displayed in numbers.

In recent years, personal computers have also come to be equipped with graph display functions. However, when displaying a graph, as mentioned above, it is simply a graph display of the desired result, and the relationship with the original take or parameter that is the basis of the display is emphasized. Therefore, it is inconvenient to grasp at once how the resulting graph display will change due to partial replacement of source data or change of parameters, etc. in relation to changes in source data and parameters. Ta.

A typical example is that changes to source data or parameters are processed according to tables or formulas on a separate screen, and the results are displayed in a graph by changing the screen again, and the relationship between the data and the graph is known. It was difficult.

Purpose The present invention has been made in view of the disadvantages of the prior art described above, and its purpose is to dynamically grasp the correlation between graph output and the original data and parameters on which it is based. However, the object of the present invention is to provide a graph processing device.

EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the functional configuration of a graph processing device according to an embodiment. In the figure, l is a keyboard 2 for inputting data and commands, and is a microprocessor including 7 AM, RO to 4, tabulation means 3 that mainly generates and processes table patterns, and graph generation means that generates and processes graph patterns. 4 functions are realized. Reference numeral 5 denotes a CRT display section which outputs the table pattern output from the tabulation means and the graph pattern output from the graph generation means on the same screen.

Inputs to the tabulation means 3 include table type selection commands, table data, display commands, and the like. This will be explained according to the flowchart of the tabulation means shown in FIG. 2. In step 1, key human power information is identified.

If the input is a table type selection command, the process advances to step 2 and the graph generation means is deactivated. This is an optional feature that disables the previous graph display by selecting a new table type when a table and graph have already been displayed due to a previous operation. Avoid misunderstanding the relationship with patterns. In step 3, a code list that generates a table pattern is selected and called. A code list for generating a table pattern for each size is stored in memory in advance and is called up according to the selection code in the selection command. The code list that generates the front pattern is converted into a front pattern in the order according to the scanning lines of the display section, transferred to a video RAM (not shown), and displayed as a pattern on the screen 10. This pattern display will be made in one of the 100 divided display areas of the screen, which will be discussed later. In step 4, the display position of the cursor is initialized. The cursor is usually placed at the first data input position inside the table pattern composition frame, and the operator inputs table data by following this cursor position or by moving the cursor appropriately. Next, if it is identified as tabular data in step 1, step 5
Then, data is added to the code list that generates the table pattern. This data is usually a number of data codes and is stored sequentially in an area for data correlated with the code list that generates the table pattern. The data area is divided into table constituent frames, and code information for identifying the row name and column number to which the data belongs is added to each frame for convenience in later processing. The data field within the frame is given a relative address to store the input character or the cursor. Of course, step 3 above
The court list that is selectively called up may include table data input in advance in this manner. In this case, the operation in step 5 is mainly a change operation of table data, so the code list that generates the table pattern containing the final table data obtained in this way is stored in a suitable memory. It is also possible to evacuate and store it somewhere. And displaying a code list containing such tabular data is as follows:
Numerical takes are displayed in divided areas of the screen 10 in the form of a table pattern with numerical takes arranged.

The graph generating means 4 will now be explained. In the flowchart showing the function of the graph generating means shown in FIG.
Inputs to the means 4 include selection commands and display commands for each graph category. When a graph type selection command is identified in step 1, the process proceeds to step 2, where a code list for generating a graph pattern is selectively called. The graph type can be a pie graph, a bar graph, a line graph, etc. If you specify this from the keyboard 1, the constituent data of the table pattern can be expressed in the graph of the operator's preference. The code list that generates the pattern of the graph is selectively called fL. This code list consists of a confirmed part of the code take that has already been decided and an undefined part that has not yet been decided. The determined part is a code take that makes up the entire circle, and this part is displayed at this point even if the table data that influences the size of the graph pixels is not determined at all. In a bar graph, the coordinate axes corresponding to the X and Y axes are already displayed1.The operator can grasp the outline of the graph from this preliminary display and enlarge or reduce the circle display if necessary. You may also add functions and operations that allow you to do this. The undetermined part is code data that generates a line segment vector Bakun to divide the display of this circular pattern with straight lines along the arc, and also corresponds to the pie chart formed by inserting dividing lines. This is code data for displaying a new item or column item in a table, and is not finalized unless the table data is input.

FIG. 4 shows one aspect of the display screen divided into 100 parts.

Here, both sides 10 are divided into a front pattern display area 11 and a graph pattern display area 12.

Further, in FIG. 5(5), a table 13 in the display area 11 in FIG. 8 showing an example of display according to this division is composed of a new item Ilho and column items A to E. Table data may be entered directly from keyboard 1,
By inputting data in columns A and B, the value in column C may be automatically determined according to a predetermined arithmetic expression. When the input of such table data is completed, the operator selects the display row Il fc where he wants to display the graph and the display column A-
Enter the command to specify E. This specification can be made directly by using the J11 item that indicates the row or column, or by placing the cursor on the table data and specifying the row and column that include the take. . In this case, the identification code indicating the row or column of the take assigned to each constituent frame of the table is referred to.

Returning to FIG. 21ξ2, in step 1 of the tabulation means, when the display row or column designation command is identified, the process proceeds to step 6, where the specified table data silk and its attributes are transferred to the graph generation means 4. For example, when column E is specified, the set of table data is 8, 4, 2.degree. 1.1, and the attributes are data corresponding to rows A to H that are subordinate to column E. Further, such row and column designation may be performed over a plurality of rows and columns, and a combination thereof.Next, the operator inputs a display command. The display command is identified in step 1 of FIG. 3 and flow proceeds to step 3.

In step 3, the graph generation means 4 determines the undetermined portion of the code list for which a graph pattern is to be generated;1. Do the following. Since the processing routine that performs definite operations is unique to pie charts, it is called together with the "no routine list" that generates pie chart patterns.This processing routine is the same as the one in the embodiment. According to one aspect, the sum of data (8+4+2+1+
1=16).

Next, calculate the proportion of data in rows I to H.

Next, from the center of the circle already displayed according to this ratio, a Verchtl pattern of line segments dividing the arc according to this ratio is generated and stored in the video RAM. Next, the tops of I to E are displayed at each corresponding graph pixel portion of the pie chart display, and the column item E is additionally displayed at the upper right of the pie chart. These processes are for determining undetermined portions of the code list that generates the pie chart pattern described above. Figure 5 (5
) shows an example of displaying the results in this case, where 14 is a pie chart that is displayed after the finalization.

In this way, the present invention has table pattern 13 and graph pattern 1.
By simultaneously expressing 4, it is possible to clarify the relationship between the two, and when it comes to individual data, it is possible to accurately understand the data numerically by using tabular expressions, and the relative relationships between these data can be expressed graphically. Expression makes it easier to understand. Data, generally presented in tabular form, often indicates a certain event. Furthermore, the present invention
It also makes it easy to dynamically grasp and dynamically predict such events. This point will be explained below using FIG. 5(C). In the figure, table data 2 in row A and column E of table pattern 13
4 indicates that the operator changed the value indicating this event from 8 to 24. This change is easily made by performing step 5 of the tabulation procedure in FIG. Further, the reason for changing the table data to 24 may be based on simply wanting to predict changes in the entire event. In the embodiment, since it has already been designated to display column E in a graph, data changes to this data string area are constantly monitored. Therefore, when there is a change in data in this row area (8→24), step 6 is activated from the monitor 7 in FIG. 2, and the tugboat operates so that step 3 in FIG. 3 is activated.

The monitor 7 is provided for the purpose of speeding up processing in order to facilitate dynamic control of events.

Therefore, the graph generating means 4 promptly performs recalculation to determine the graph pattern 1 shown in FIG. 5 (13).
4 is displayed again. In addition, other table data such as row A, 13
Even if the value in the column is changed, if this change changes the value in row A and column E, which are correlated in the predetermined performance relationship, it is possible to make the monitor 7 work in the same way.1 In this way, the operator The change in the table data is arbitrary, and the graph pattern 14 changes rapidly as shown in the figure, so it is possible to dynamically grasp the phenomenon indicated by the change in the table data.

In the above-mentioned embodiment, CI (
, the T display unit 5 is used, but other liquid crystal displays, display devices, semiconductor display devices, plasma display devices, etc. can be applied, and if a printer device is used, the display can be preserved and it is convenient. good.

Effects As described above, according to the present invention, a graph processing device is proposed which can grasp the relationship between a graph display and its underlying table data and parameters at once. Generally, data consisting of numerical values and variations are expressed in tabulations. It is a so-called digital representation and is convenient for accurately recognizing individual values. On the other hand, graphic representation is similar to analog representation and is more convenient for understanding relative relationships between data than individual values. In this way, by simultaneously expressing a certain phenomenon digitally and analogously, it becomes possible to understand it more deeply and accurately.5 Furthermore, according to the present invention, it is also possible to grasp these phenomena dynamically. . Changes in table data or parameters are immediately visible as changes in the graph representation. Moreover, this table data and parameters are accurately digitally expressed in the form of tabulations, so 1.
The effect that a change in one element (data or parameter value) has on the entire table can be numerically accurately known, and its graphical representation facilitates dynamic recognition. Therefore, it is particularly effective when grasping all variables including multiple variables at once.
