Abstract

PURPOSE:To easily select the type of an optimum graph by outputting simultaneously and visibly the graph patterns when an original piece of numerical data is shown in plural graphs. CONSTITUTION:A graph production data storage area is provided to store the original numerical data for production of a graph together with a RAM 5 which contains a graph storage area to store the data transformed into a graph, and a ROM 3 which includes a storage areas to store the graph production programs A and B, etc. Then plural graphs of different types are produced a single type of graph production data and at the same time these graphs are simultaneously displayed on the same screen. Thus it is not required to repeat the graph displaying operations. Furthermore the comparison is possible on the same screen among different ways of showing graphs of different types via the same data. Thus the comparison can be carried out at a higher speed among the graphs of different types.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a data processing device capable of displaying graphs for Japanese desktop publishing systems and word processors.

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

Problems to be Solved by the Invention However, with the conventional methods described above, it is not possible to display different types of graphs simultaneously on the same screen, so it is necessary to select the optimal graph type for the data to be graphed. In order to do this, it was necessary to compare and select the types of graphs that the system had by repeatedly displaying and deleting them. 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 and compare them.

Means for Solving the Problem In order to solve this problem, the present invention provides a graph creation means for creating multiple types of graph data based on numerical data to be graphed, and a The apparatus includes display means for visually displaying graph patterns simultaneously, and means for indicating one of the displayed graph patterns.

Effect: With this configuration, graph patterns obtained when a single source numerical data is represented by a plurality of graphs are simultaneously output visually.

Embodiment Hereinafter, a data processing apparatus 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 a data processing apparatus according to this embodiment. Here, 1 is a keyboard for inputting character data, numerical data, commands, etc. 2 is a pointing device that generates pulses as it moves and updates coordinate data. Reference numeral 3 denotes a read-only memory (hereinafter referred to as ROM), which includes a control program storage area for storing a control program according to the flowchart shown in Fig. 2, and for graphing original numerical data when graphing. It has storage areas in which several graphing programs are stored, such as a graphing program A storage area and another graphing program B storage area.

4 is a display device composed of a CRT or the like for displaying characters and figures. Reference numeral 5 denotes a writable and readable random access memory, which includes a graphing data storage area for storing original numerical data for graphing, a graph storage area for storing graphed data, and a pointing device 2.
It has a coordinate data storage area that stores coordinate data that is updated according to the movement of the mouse cursor and becomes 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 character and graphic patterns to be displayed on the display device 4 are developed in the form of a bitmap. 7 is RO
In accordance with the control program stored in M3, it performs calculations for graphing processing and develops patterns in display memory 6.

The operation of the data processing apparatus configured as described above will be explained according to the flowchart shown in FIG.

First, in step 8, input is made from keyboard 1,
Among the data stored in the graphing data storage area, the designation of the data to be graphed now is accepted. Step B
Now, store the graphing data specified in step B in RAM.
Import into the work area of 5. In step C, RAM5
Convert the graphing data imported into graphing data into graphing data by graphing program A stored in ROM3,
It is stored in the graph storage area of RAM 'M5. When graphing by the graphing program A is completed, graphing is performed by the graphing program B and stored 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, the graph data created in step B is developed into a graph pattern and stored in the display memory 6. The plurality of graph patterns stored in the display memory 6 are displayed on the display device 4. Then, in step E, which of the plurality of displayed graph patterns has been indicated by the operator is identified based on 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 Then, the details of the specified graph are displayed, and the graph data of the graph is stored in the document memory, and the process ends.

FIG. 3 shows an example of displaying a plurality of graph patterns.

Effects of the Invention As described above, it is possible to generate multiple types of different graphs from one type of graphed data, and since these multiple graphs are displayed simultaneously on the same screen, it is no longer possible to select the optimal graph type as before. There is no need to repeat the operation of displaying a graph multiple times in order to select a graph, and the appearance of different graph types for the same data can be compared on the same screen, making it possible to compare graph types more quickly. It becomes like this.
