The present invention is characterized by providing means for automatically drawing a graph.

[Embodiments of the invention]

Hereinafter, an example in which the present invention is applied to graph drawing on a keyboard-type Japanese word processor will be explained with reference to the drawings. FIG. 2 is a block diagram schematically showing the hardware configuration of a keyboard-type Japanese word processor to which the present invention is applied. 200 is a display device for displaying graphs, characters, numbers, and operating procedures; 210 is a storage device for storing graphs, characters, numbers, and programs;
220 is an input device for inputting graphs, characters, numbers, and operating procedures; 230 is an output device for printing and outputting documents and graphs; 240 is each of the devices 20
This is a processing device that controls 0 to 230.

FIG. 3 shows the key arrangement on the keyboard surface of the input device 220. 221 is a numeric keypad that allows you to directly input numerical values; 222 is a cursor key that directs cursor movement; 223 is an execution key that executes each processing function of the word processor; 224
is a cancel key to cancel each processing function,
225 is a previous item key for switching from the graph configuration item setting screen to the graph format setting screen, 226 is a next item key for switching from the graph format setting screen to the graph configuration item setting screen, 227 is the next key, and 228 is the previous key.

In such a keyboard type Japanese word processor, graphs such as bar graphs, line graphs, point graphs, pictorial graphs, pie graphs, etc. are displayed on the display device 2.
FIG. 4 shows the processing procedure for displaying the data in 00 or printing it on paper using the output device 230 and outputting it.

In process 401, a graph work menu is displayed on the display device 200, and the operator uses the numeric keypad 221 of the input device 220 to specify whether to create a new graph, update the graph, or the like. When the operator presses "1" on the numeric keypad 221 to designate the creation of a new graph, the process moves to step 402 where the graph format setting screen shown in FIG. 5 is displayed. , graph type, graph shape, number of components (component elements for graphing,
Specific components include: for graphs by product, this corresponds to TV, radio, etc.; for graphs by year, this corresponds to the fiscal year), number of items (number of items for each component, specific items) (In the case of a monthly graph, this mainly includes permuted numerical values such as January and February) is input and stored in the storage device 230 by the processing device 240. In the example in Figure 5, graph type: multiple graphs,
Graph type: the first graph is a comparison bar graph, the second graph is a line graph, graph shape: vertical, number of configurations: 3 for both the first and second graphs, and number of items: 3. Subsequently, when the next item key 226 of the input device 220 is pressed, the process moves to step 403, and the graph configuration item setting screen shown in FIG. 6 is displayed in accordance with the input data for the graph format setting. The operator inputs a configuration name 601, an item name 602, and a numerical value 603 to be graphed according to the number of configurations and items, as shown in FIG. By pressing the execution key 223 of the input device 220, the processing device 240
stores these in the storage device 210, performs consistency determination between the graph format value input in the graph format setting and the graph, coordinate calculation, etc., and displays the designation as shown in FIG. 8 on the display device 200 in process 404. Display the graph.

By the way, conventionally, when creating a composite graph on the graph format setting screen shown in FIG. 5 and the graph configuration item setting screen shown in FIG. Data to be graphed is entered on the input device 220 according to the item setting screen. When pressing the key, use the cursor key 222 to move the cursor 604 to the graph pattern area 605 on the graph configuration item setting screen in FIG.
By moving , a graph pattern matrix 606 is displayed, and a desired pattern is selected using the numeric keypad 221 corresponding to the graph pattern matrix. The display of the graph pattern in the graph pattern matrix is as follows:
It depends on the graph type on the graph format setting screen in FIG. 5, and other types of graph patterns are not displayed.
For example, if the first graph type on the graph format setting screen in Figure 5 is set to a comparison bar graph, the graph pattern of the first graph will be a filled pattern, and it will not be possible to display line patterns, dot patterns, pictographic patterns, etc. Yes, if you want to set the graph pattern of the first graph to a pictorial pattern, press the previous key 225 on the input device 220 to return to the graph format setting screen of FIG. 5, and change the graph type of the first graph to a pictorial graph ( After resetting to stacked picture graph or comparative picture graph, input device 220 again.
The user presses the next item key 226 and moves the cursor 604 to the graph pattern area 605 using the cursor keys 222 on the graph configuration item setting screen shown in FIG. 6 to select and set a pictorial pattern.
For example, if there are two graph scales as shown in Figure 8 or Figure 14, two different types of graphs (line graph and bar graph, line graph and point graph, line graph and pictorial graph, etc.) can be created. However, it is not possible to create or display more than three graphs (such as a line graph, bar graph, point graph, or a graph that includes a pictorial graph). In addition, in the sixth graph configuration item setting screen, there is a boundary between data to be graphed between a data input section 607 for the first graph and a data input section 608 for the second graph. Settings can be made by changing the number of first graphs or the number of second graphs on the graph format setting screen shown in FIG. It was impossible to mix the data input section 608 to be graphed with the second graph.
