JP3015372B2 - Document creation device - Google Patents

Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a document creation device, and more particularly, to a document creation device capable of creating a graph with more expressive power than before.

[Prior Art] In a conventional computer such as a personal computer and an office computer, for example, a graph edition of Hitachi Integrated Japanese Word Processor BW-1000 Operation Manual (issued on July 20, 1987) As described in (1), the input of characters and figures into the graph is uniquely incorporated based on the graph creation function.

[Problems to be solved by the invention]

The input of characters and graphics to a graph by the conventional document creation device is performed as described above. However, according to the graph creation function described above, the name, the position for inserting the item, and the number of usable characters are fixed and cannot be changed. However, there is a limit in its expressive power as compared with the figure creation function.

Therefore, if a graph is edited based on a graph creation function with a limited expressive power, the expressive power tends to lack richness, and it has been difficult to create a highly expressive graph.

The present invention has been made in view of the above, and an object of the present invention is to create a highly expressive graph by a graphic creation function when creating a graph on a personal computer, an office computer, or the like. It is an object of the present invention to provide a document creating device capable of performing the following.

[Means for solving the problem]

The present invention provides an input device for a graph creation operation, a display device for displaying graphs and characters, a memory for storing graph data input from the input device, and a function for displaying or printing out based on the graph data. And a means for converting graph data input based on a graph generation function into graphic data, and then generating a graph based on the graphic data.

[Action]

According to the present invention, when a graph is created by a document creation device, graph data created based on a graph creation function is converted into graphic data, and then a graph is created based on the graphic data. Even if the graph data is created based on a graph creation function with limited expressive power, a highly expressive graph can be created by freely editing the graph, that is, a graphic creation function.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a display example of a graph obtained by the present invention.
The figure shows a state in which a rectangle 1 and a character string 2 have been input by the graphic creation function after converting the graph data into graphic data.

FIG. 2 is a block diagram showing the overall configuration of the document creation device.

2, 3 is a central processing unit (CPU), 4 is an input device such as a keyboard or tablet, and 5 is an input device 4.
6 is a printer, 7 is a secondary storage device composed of a floppy deck, 8 is a read-on memory (ROM), 9 is a random access memory (RAM), 10 is a sub-processing device (sub-CPU), 11 is It is a display device such as a cathode ray tube.

In the above configuration, graph creation is performed as follows.

First, by loading a control program from the floppy disk in the secondary storage device 7 into the RAM 9 according to the load program in the ROM 8, data input from the input device 4 is processed by the CPU 3 based on the control program. The result is temporarily stored in a data area in the RAM 9, and the data stored in the data area is displayed on the display device 11 by the sub CPU 10, printed by the printer 6, or stored in the secondary storage device 7. Store it on a floppy disk.

At this time, the graph data has already been expanded in the RAM 9 as shown in FIG. 3 by the data creation function.
FIG. 4 illustrates a bar graph as a type of graph. In FIG. 3, 12 is graph format data, 13 is graph name data, and 14 is graph numerical data.

The coordinate axis 15 of the graph of FIG. 4 is used as the polygonal line data 19 of FIG. Therefore, the graph data of FIG. 3 can be converted into the graphic data of FIG. 5 according to the processing flow of FIG. Specifically, the sixth
As shown in the processing flow of the figure, the graph data shown in FIG. 5 is equivalent to the graph data shown in FIG. 5 by the program (data conversion means) in the RAM 9 loaded from the floppy disk in the secondary storage device The data is converted into data by the CPU 3 and registered as graphic data at another position in the RAM 9.

In the above-described embodiment, the case where the bar graph shown in FIG. 4 is converted into the graphic data shown in FIG. 5 based on the graph data shown in FIG. 3 is illustrated. Data can be converted by similar processing.
The timing of converting the graph data into the graphic data may be given by, for example, inputting a function key in a key row indicated by reference numeral 5 in FIG. 2 after displaying the graph.

Then, the graph data converted into the graphic data as described above is edited as a graph by a graphic creation function with rich expressive power.

〔The invention's effect〕

According to the present invention, after converting graph data into graphic data, a graph is created based on the graphic data, so that a highly expressive graph can be generated.
