Reference numeral 4 denotes a display device having a screen D, which displays a graph creation result, program processing designation, and the like.
In this embodiment, the screen D is regarded as, for example, A4 paper (paper) to create a graph. An input device 5 includes a keyboard K and a mouse M. Keyboard K
Various commands and numerical values are input from the mouse, and position data indicating the position of the cursor is input from the mouse M. Then, these input commands and position data are supplied to the CPU 1 via the control unit 6. The control unit 6 controls the display of the display device 4, performs key scanning of the keyboard K, and the like.

Reference numeral 7 is a storage device for writing / reading a data file, and 8 is a printing device. The printing device 8 includes an xy plotter PL and a page printer PP.
Is used. The storage device 7 and the printing device 8 are each connected to a bus via an interface.

Next, the structure of data used in this embodiment will be described. As shown in FIG. 2, when the vertical axis is plotted on a different scale, or when multiple graphs with one axis being the same and the other axis being different are simultaneously expressed for mutual comparison, etc. Then, the coordinate of one axis is defined with respect to the coordinate of the other axis. A plurality of such coordinate data (one may be defined) is defined as a group in this embodiment.

Here, the coordinate data in one group will be described. In FIG. 2, 10-1 to 10-n
(N is an integer), the x-axis is the same, and the y-axis is y1 ...
It is a graph with yn. The common x-axis coordinate is X0, X
, X2, ..., Xm (m is an integer), the y-axis coordinates of the corresponding graph 10-n are Yn0, Yn1, Yn2 ,.
… Ynm. The coordinate data of this group is defined by the following method.

FIG. 3 is an example of the coordinate data in FIG. In this figure, “data No.” is a number sequentially assigned to the coordinate data from 1. Among these, the coordinate data corresponding to 1 of "Data No." is a sequence of common x coordinates, and the coordinate data corresponding to 2 of "Data No." is the y1 axis of the graph 10-1. Coordinate data is data No. They are arranged in the order corresponding to 1. Similarly, the coordinate data corresponding to (n + 1) (n is an integer) of “Data No.” is the yn axis coordinate data of the graph 10-n. They are arranged in the order corresponding to 1. That is, there is only one data in which x-coordinates are listed in one group. Therefore, when there are n graphs, x-axis coordinate data and n y-axis coordinate data are prepared, so that (n + 1) coordinate data are prepared for one group. become.

Next, "group No." is a number used to identify a group. In FIG. 3, since the data is in the same group, the same “group No.” is assigned to “data No.”. Also,
“Plot No.” indicates a plot point shape when a graph for “Data No.” is drawn.
The coordinate data corresponding to 1 of "Data No." is
Since the position data has common x-coordinates, a plot point shape is not necessary, and "Plot No." is omitted. The order of "data No." is arbitrary. In this way, the coordinate data, the "group No.", and the "plot No." are set for the "data No.", respectively, and the plot data file 11 is configured by these.
In addition to "Plot No.", "line type", "pen (thickness, color)", "designation of drawing area", etc. are defined in the same manner, but the description thereof is omitted here.

Next, the operation of this embodiment will be described. First, when the power of this device is turned on (or reset), the CPU 1 initializes each unit, and the operation program of the flow shown in FIG.
Read from and start this operation program. As a result, the flow proceeds to step SP1.

At step SP1, the paper is vertically or horizontally arranged. Here, the operator selects either one using the mouse M or the keyboard K. This selection result is sent to the CPU 1 via the control unit 6.
Transferred to. The CPU 1 supplies the image data of the paper layout based on the transferred selection result to the control unit 6 to display the paper on the screen D. On the screen D, the paper of the layout selected by the operator is displayed.

After this display, the flow proceeds to step SP2, and the screen D displays the paper in the center and the main menu on the top. Various processing items correspond to this main menu, and more detailed processing is prepared in a layer below this processing item. In this embodiment, graph creation is explained as an example, so the flow advances to step SP3.

At step SP3, the operator determines whether to set various data. When setting various data, it is determined as "YES" and the flow proceeds to step SP4. When not setting various data, it is determined as "NO" and the flow proceeds to step SP5. When this operation program is executed and the process proceeds to step SP3 for the first time, it is necessary to set various data necessary for creating a graph, so the flow is step SP.
Go to 4.

In step SP4, "x, y axis setting", "coordinate data setting", "comment / parameter setting", and "frame / mesh setting" are performed.
First, "setting of x and y axes" will be described. Before creating a graph, it is necessary to set at which position on the paper the x and y axes that are the basis of the graph are arranged and how the x and y axes are drawn. Therefore, the operator moves the mouse M to specify the position where the coordinate axes are to be drawn on the paper displayed on the screen D, inputs the initial values of the coordinate axes, and inputs the maximum values of the coordinate axes. Enter the step size of each coordinate axis in mm, enter the scale step of each coordinate axis (increment of the scale per interval), and enter the title of each coordinate axis. The data input by these are transferred to the CPU 1 via the control unit 6. The CPU 1 arithmetically generates image data based on this data and supplies it to the control unit 6.
As a result, the coordinate axes set in the paper are displayed on the screen D.

Then, "setting of coordinate data" is performed. Manual input, which is an example of this setting, will be described. The operator is A. Specify which coordinate axis to assign the data to, and B. Plot No. Select (0-8), Enter the group number of the data to be defined, D. Enter the number of data to be input, and E. Enter coordinate data in order. The plot data input by A to E is stored in the RAM 3 via the control unit 6, and a plot data file 11 as shown in FIG. 3 is created in the RAM 3.

Next, "comment / parameter setting" is performed as necessary. A comment is character information displayed at any position on the graph, and a parameter is
It is a description such as a graph line and a plot point shape. In this setting, the position to start writing is designated on the sheet of screen D by the mouse M, and the character information is input by the keyboard 6. The input data is RA through the control unit 6.
The data being input is displayed on screen D while being stored in M3.

Similarly, "frame / mesh setting" is performed as necessary. Here, the frame is a line surrounding a graph or a comment, and the mesh is a mesh line parallel to the x and y axes. In the frame setting, the upper left and lower right points of the frame are designated by the mouse M, respectively. Similarly, the mesh setting is also designated by the mouse M. The data designated by the mouse M is stored in the RAM 3 via the control unit 6. In this way, in step SP4, various data necessary for creating the graph are set.

Next, in step SP5, step SP
It is asked whether or not to display a list of the data set in 4. If the operator needs to list the data, "YES" is selected and the flow is step SP.
On the other hand, if it is not necessary to display the list of data while proceeding to step 6, "NO" is selected and the flow proceeds to step SP7. At step SP6, the CPU 1 transfers the data necessary for creating the graph from the RAM 3 to the read control unit 6. As a result, the data itself is displayed on the screen D, so that the operator can know the setting status of the data.

At step SP7, it is asked whether or not the data set at step SP4 should be modified. If the operator needs to correct the data, the "Y
While "ES" is selected and the flow proceeds to step SP8, if the operator does not need to correct the data, "NO" is selected and the flow proceeds to step SP9. At step SP8, when data to be corrected is specified by the operator and new data is input by the keyboard K or mouse M, the CPU 1
Transfers the input data to the RAM 3 via the control unit 6. As a result, the data before correction is rewritten with the newly input data.

Next, in step SP9, it is asked whether to change the set value of the system. The set values of this system are "sensitivity of mouse M", "execution speed of CPU 1", and "drawing speed of printing device 7", "sensitivity of mouse M" is resolution, and "execution speed of CPU 1" is Calculation speed,
The "drawing speed of the printing device 7" indicates the pen drawing speed of the xy plotter PL. If it is necessary to change the system setting value, "YES" is selected and the flow proceeds to step SP.
Meanwhile, if there is no need to change, “NO” is selected and the flow proceeds to step SP11. Step S
At P10, the operator specifies a setting value to be corrected and inputs a new setting value with the keyboard K or mouse M. As a result, the CPU 1 transfers the input set value to the RAM 3 via the control unit 6. As a result, the setting value before correction is rewritten with the newly input setting value.

Next, in step SP11, it is asked whether or not to display a graph. When displaying a graph,
If "YES" is selected and the process proceeds to step SP12, if not displayed, "NO" is selected and step SP1.
Go to 3. At step SP12, the CPU 1 makes the RAM 3
The coordinate data of the group selected from the plot data file 11 is read out from the inside, converted into the coordinate axes on the screen D, and plotted in the plot shape designated by the "plot No.". As a result, the graph as shown in FIG. 2 is output based on the set data. The data corresponding to each y-axis (y1 to yn) is Δ, □,
It is plotted in a shape such as ◯, and these plot points are drawn with the set line type. The output destination is selected by the operator from the page printer PP, the xy plotter PL, or the display device 4.

At step SP13, the operator determines whether or not to create a file. There are two files, a plot data file and a file relating to the setting of coordinate axes. When it is not necessary to create the file, it is determined as "NO", and the flow is step SP1.
When it is necessary to create the file, it is determined to be "YES", and the flow proceeds to step SP14.

At step SP14, the CPU 1 has a RAM
A file is created from the data stored in 3 and stored in the storage device 7. As a result, it becomes unnecessary to set various data in step SP4 by reading the saved file at a later date. In this embodiment, the plot data file and the coordinate axis setting file can be stored separately.

At step SP15, the operator determines whether or not to refer to the manual. The manual here is textual information that explains how to use the program. When it is not necessary to refer to the manual, the operator determines "NO", and the flow proceeds to step SP17. On the other hand, when it is necessary to refer to the manual, "YES" is determined, and the flow proceeds to step S17.
Go to P16.

At step SP16, the CPU 1 executes the ROM
The manual file is read from the file 2 and transferred to the control unit 6. As a result, on the screen D, the usage method of the program is displayed for each item, and by specifying the item with the mouse M, the detailed usage method of the item is displayed. When this display is completed, the flow proceeds to step SP17.

At step SP17, the operator determines whether or not to end this program. If it is ended, it is determined to be "YES", and the flow is ended. If it is to be continued, it is determined as "NO", the flow returns to step SP2, and the program is continued.
