Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interactive plotting device that determines the recording position of an axis label for a graph drawn on a recording surface by the interactive plotting device and records the axis label at the appropriate position. be.

Conventionally, there has been an interactive plotting device that inputs plotting information from a keyboard in an interactive manner with a processor using a microprocessor, etc., and plots a desired bar graph, line graph, etc. according to a predetermined plotting program. . FIG. 1 shows an example of a conventional interactive plotting device of this type particularly equipped with a CRT display. In FIG. 1, 1 is a keyboard consisting of letters, numbers, symbols, and various function keys; 2 is a processor;
3. Programs related to drawing etc. were memorized.
ROM (Read Only Memory), 4 is RAM (Random Access Memory) that can store input information etc. as needed and read the stored data;
Reference numeral 5 represents a display for displaying messages and the like to guide input of drawing information, 6 represents a CRT, and 7 represents a recording device such as an X-Y plotter.

The processor 2 executes the drawing program stored in the ROM 3, and when requesting input of drawing information, causes the display 5 to display an input request message.
The operator inputs appropriate information from the keyboard 1 in response to this message. This message and information input is performed step by step, and a drawing based on the information thus input is drawn on the CRT 6. In this case, the display position of figures, characters, etc. can be determined by controlling the movement of, for example, a cross-shaped indicator (hereinafter referred to as a cursor) displayed on the CRT 6 screen using the keyboard 1. When recording a so-called axis label such as a numerical value to be attached, the desired axis label can be easily displayed by specifying the label position using this cursor. The graph drawn on the CRT 6 can be hard-copied using the recording device 7.

However, although such devices are suitable for drawing precise technical drawings, etc., they not only require extremely complicated operations, require specialists or skilled workers, and are expensive. It is not suitable as a device for drawing relatively simple graphs.

Therefore, recently, in the configuration shown in Figure 1, CRT
An easy-to-operate, inexpensive interactive plotting device has emerged in which the plotting function has been reduced to only the plotting function of graphs, etc. However, such simple devices are configured to draw graphs directly on the recording device, and do not have a CRT monitoring function like the device shown in Figure 1, so axis labels must be recorded at appropriate positions. It was extremely difficult to do so, and if a mistake was made, the paper had to be replaced and the drawings had to be started all over again.

In view of these points, the present invention attempts to provide an interactive plotting device that can position and record axis labels at appropriate positions with a simple operation in a CRT plotting display interactive plotting device. It is.

The present invention will be explained in detail below using the drawings. FIG. 2 is a block diagram of an interactive drawing device according to the present invention. In FIG. 2, 1a is a keyboard consisting of function keys such as letters, numbers, symbols, and axis labels; 2a is a processor; 3a is a program for locating axis labels and calculating numerical values of the labels; 4a is a RAM, 5a is a display, and 7a is a recording device; these are, for example, the third
As shown in the figure, it is constructed in one piece to improve operability.

When drawing a graph with such a configuration, draw the axis, graph, and axis label in this order. The plotting of axes and graphs is performed in the same manner as in a normal plotting device, but since this operation has little direct bearing on the present invention, its explanation will be omitted here, and only the operation of axis label recording will be explained next.

FIG. 4 shows the operating procedure; the left side shows the operation keys of the keyboard 1a, and the right side shows the display on the display 5a that appears in response to key operations.
First, press the "axis label" key on the keyboard 1a. As a result, the processor 2a starts executing the axis label writing program in the ROM 3a, and instructs the display 5a to display "JIKU LABEL Gaki". Next, press the "Input" key, and display 5 will appear.
The display "X Tab Interval=" appears in a.
Tab interval means how many divisions the label is recorded for the division of the X-axis. For example, in the graph shown in Figure 5, the division of the X-axis is 6.
When "1" is keyed in as a parameter from the keyboard 1a, "X tab interval=1" is set, which promises to record the X-axis label on a one-to-one basis for each data. In addition, “X Tab Kankaku =
0" has a special meaning, and is automatically labeled as 0, 1, 2, . . . , n.

Next, when you press the ``input'' key, a message ``Y tab change='' will appear regarding the Y-axis label. On the other hand, if you enter the parameter "0", "Y tab interval = 0" will be generated, and the label scaled between the maximum value and minimum value of the data will be
Apply to the shaft.

Subsequently, the processor 2a determines the position of the X-axis label. For example, in the case of a line graph, the position is set at twice the height of the label character below the X-axis line under each scale. In addition, in the case of a bar graph, as shown in Figure 5, the height of the characters should be 2
Determine the axis label position (corner frame part in the figure) at the double position. When the positioning of the first X-axis label is determined in this way, a message "X label 01=" appears on the display 5a, and the label characters are input from the keyboard 1a. For example, if you want to record "April", you may input Kirakuta "4" and "Month" in sequence.

After finishing recording the first label, press the "Enter" key. "X Label 02=" will be displayed, so change the character of the second label (for example, 5
month). At this time, under the control of the processor 2a, "May" is recorded from below the leading edge of the second bar as shown in FIG.

From then on, record the X-axis label using the same procedure.
The Y-axis label is positioned at a position five times the label character size from the origin of the graph, as shown in FIG. 5, so that a four-digit numerical label can be written.

When label recording is finished, press “Enter” on keyboard 1a.
The user presses the key to notify the processor 2a of the end of recording, and the axis label recording operation is ended with the display 5a displaying "DICLABEL OWARI". In this way, the axis label can be recorded at an appropriate position with a simple operation. The means for controlling and executing the axis label recording 2 in this way, that is, the axis label recording control means, includes the processor 2a, the ROM 3a,
It is provided in the part consisting of RAM4a. The program to record axis labels as above is
The program is stored in the ROM 3a and executed by the processor 2a. Also keyboard 1
Input information (parameters) from a as necessary
It is appropriately stored in the RAM 4a and referenced by the processor.

In the example, only the case where the axis label is recorded from the determined position is explained, but
If a space key, half-step space key, back step key, etc. are provided, even more precise positioning will be possible on both the X and Y axes.

Further, although the display on the display 5a is in katakana text, the display is not limited to this, and may be displayed in other formats such as English text.

Furthermore, the Y-axis label is automatically scaled from the maximum value (Ymax) and minimum value (Ymin),
In other words, (Ymax-Ymin)/Number of Y-axis divisions is taken as one step, but it can be applied not only to the Y-axis but also to the X-axis, and other calculated values or input data from the keyboard can also be recorded. can.

As explained above, according to the interactive plotting device of the present invention, the axis label positions related to the plotted graph are automatically determined by the simple operation of inputting parameters from the keyboard, and the information input is easy. This allows the desired axis label to be recorded at the determined position without error, which is highly effective in practical use.
