Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device capable of displaying a graph of a Japanese desktop publishing system or a word processor.

2. Description of the Related Art Conventionally, when displaying numerical data or character data in the form of a graph, one type of graph is displayed on a display device after specifying the data to be graphed. At this time, in order to display a graph of a different type for the graphed data, the graph type was instructed to be changed, the previously displayed graph was erased, and a new type of graph was displayed from above. ..

However, in the conventional method as described above, different types of graphs cannot be displayed on the same screen at the same time, so the optimum graph type is selected for the data to be graphed. In order to do this, it was necessary to repeatedly display / delete graphs according to the types of graphs that the system had, and to select by comparison. Furthermore, in order to compare different types of graphs side by side, it was necessary to output them to an output device such as a printer for comparison.

Means for Solving the Problem In order to solve the problem, the present invention provides an input unit for inputting various information such as characters and symbols, a document storage unit for storing data input from the input unit, a character, Display means for displaying symbols and graphs, graphing data storage means for storing numerical data input from the input means, and graph information for storing information for creating a plurality of different types of graphs Storage means, and graph creation means for creating a plurality of mutually different types of graphs based on the same information stored in the graphed data storage means, based on the information stored in the graph information storage means,
Control means for simultaneously displaying the plurality of graphs created by the graph creating means on the screen of the display means, instructing means for instructing a position on the screen of the display means, and instructed by the instructing means. One graph displayed at different positions is selected, and the selected graph is stored in the document storage means.

Operation With this configuration, a plurality of graphs of different types can be created from the same data, displayed, selected from these, and stored in the document storage means.

Embodiment Hereinafter, a data processing device according to an embodiment of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 is a block diagram showing the configuration of the data processing apparatus of this embodiment. Here, 1 is a keyboard (input means) for inputting character data, numerical data, commands and the like. Reference numeral 2 is a pointing device (instructing means) that generates a pulse with the movement of itself and updates the coordinate data. Reference numeral 3 is a read-only memory (input information storage means) (hereinafter referred to as ROM), which has a control program storage area in which a control program according to the flowchart of FIG. 2 is stored, and original numerical data for graphing. It has a storage area for storing some graphing programs, such as a graphing program A storage area for graphing etc. and another graphing program B storage area. 4 is
Characters and figures are displayed on a display device (display means) composed of a CRT or the like. Reference numeral 5 denotes a writable / readable random access memory (input information storage means), which is a graphed data storage area for storing original numerical data for graphing, a graph storage area for storing graphed data, and It has a coordinate data storage area for storing coordinate data which is updated according to the movement of the pointing device 2 and serves as position data of the mouse cursor indicating the position on the display screen of the display device 4. A display memory 6 is a memory in which a pattern of characters or figures to be displayed on the display device is developed in the form of a bit map. Reference numeral 7 denotes a central processing circuit (graph creating means) for performing a calculation for graphing processing and developing a pattern in the display memory 6 according to a control program stored in the ROM 3.

The operation of the data processing apparatus configured as described above will be described with reference to the flowchart of FIG.

First, in step A, the designation of the data to be graphed is received from the data input from the keyboard 1 and stored in the graphed data storage area. In step B, the graphed data specified in step A is
Capture to RAM5 work area. In step C, the graphing data captured in the RAM5 is converted into graph data by the graphing program A stored in the ROM3 and stored in the graph storage area of the RAM5. When the graphing program A completes the graphing, the graphing program B graphs it and stores it in the graph storage area of the RAM 5. By repeating this several times, various graph data are stored in the graph storage area. In step D, based on the graph data created in step B, the graph pattern is developed and stored in the display memory 6. Display memory 6
The plurality of graph patterns stored in is displayed on the display device 4. Then, in step E, which of the plurality of displayed graph patterns is instructed by the operator is identified by the value of the coordinate data indicating the position data of the mouse cursor that moves with the movement of the pointing device 2, and in step F When the details of the instructed graph are displayed, the graph data of the graph is stored in the document memory and the process ends.

 FIG. 3 shows a display example of a plurality of graph patterns.

EFFECTS OF THE INVENTION As described above, it is possible to generate a plurality of different types of graphs from one type of graphing data, and simultaneously display a plurality of these types of graphs on the same screen. It is not necessary to repeat the operation of displaying the graph multiple times to select, and it is possible to compare the graph types faster because the appearance of different graph types with the same data can be compared on the same screen. Further, by designating a desired graph, the graph can be selected, and the usability for the user is extremely improved.
