Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a graphics device that is capable of displaying and copying a plurality of line graphs and is suitable as a device for comparing various data.

[Conventional technology]

In conventional graphics devices of this type, when a plurality of line graphs are displayed on the same coordinates, the trajectory of each graph can be easily identified by color-coding the graph lines using a color graphic display. However, if the hard copy device that draws and copies each graph line is monochrome, it is almost impossible to identify the trajectory of each graph even if the graphic image on the display is drawn as it is. For this reason, conventionally, graph lines A and B, as shown in FIG. 7, for example.

A means of making it possible to identify the type of C by drawing it as a solid line, a dashed-dotted line, a dashed-double-dotted line, or parallel to the vertical axis of the graph and equally spaced from the horizontal axis as shown in Figure 8. A method was used to record identification marks (symbols or characters) on each graph line to distinguish each graph line.

[Problem that the invention seeks to solve]

However, with the former method, if the interval between the curved points of each graph becomes as narrow as the interval between dots drawn on a hard copy device, the line drawn as a solid line and the one-dot chain line or the two-dot I
l! There was a problem that it was not possible to distinguish between the images drawn in III.

On the other hand, with the latter method, when a plurality of graphs overlap, the identification marks and graph lines are drawn in a more complex manner, overlapping each other, which may make it difficult to identify the graph trajectory.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a graphic device that can easily identify the locus of a plurality of line graphs on the same coordinates when the graphs are copied.

[Means for solving problems]

In order to solve the above problems and achieve the purpose, the present invention displays a line cursor movable in the horizontal axis direction parallel to the vertical axis on a display unit that displays a plurality of line graphs on rectangular coordinates, Each of the line graphs is identified based on the intersection between the line cursor and the plurality of line graphs, and the identified line graphs are copied by a copying section.

[Effect]

By taking such measures, the trajectory of each line graph can be made clear by moving the line cursor to a desired position.

〔Example〕

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the present invention. In the figure, reference numeral 1 denotes a controller that controls the entire graphic device, and an auxiliary storage device 2. Color graphic display (hereinafter abbreviated as display) 3. Hard copy device 4. Keyboard 5. An auxiliary input device 6 is connected. The auxiliary storage device 2 stores a plurality of line graph data and a display program, and according to the display program, line graphs, line cursors, graph identification marks (symbols or characters), etc. based on the line graph data are displayed. It is displayed on the rectangular coordinates of the display 3.

The hard copy device 4 copies the image displayed on the display 3, and the image is drawn in monochrome on copy paper. The keyboard 5 has the function of inputting a request to display a line graph on the display 3, the function of inputting a request for copying the display data displayed on the display 3 to the hard copy device 4, and the function of inputting a request to display a plurality of display data displayed on the display 3 to the hard copy device 4. It has a function of inputting a bias value to a predetermined line graph in order to reduce the overlapping portion of the line graph. As shown in FIG. 2, the auxiliary input device @6 includes a line cursor/calendar display request input means 61 for requesting the display of the line cursor, and a line cursor/calendar display request input means 61 for requesting the display of the line cursor, and this means 61 for inputting the display 3 on the display 3 based on the display program in the auxiliary storage device 2. A line cursor moving means 62 inputs a request to move the line cursor displayed above in the horizontal axis direction, and the graph identification mark is placed at the intersection of the line cursor moved to a predetermined position by this means 62 and each of the line graphs. and an identification mark display request input means 63 for requesting display of the identification mark.

Next, the operation of the present device will be explained with reference to FIGS. 3 and 4. At the start of this system,
The display program stored in the auxiliary storage bag R2 is loaded into the main storage section (not shown) of the controller 1, and processed according to the flowchart shown in FIG. 3 by the action of the controller 10. In other words, first of all, auxiliary storage! 2
The bias value of each line graph data stored in is initialized to O (step (hereinafter abbreviated as ST) 1), and the position of the line cursor is initialized, for example, on the vertical axis in rectangular coordinates (ST2> .

After the initial settings are completed, in response to a graph display request from the keyboard 5 and a line cursor display request from the auxiliary input device 6, the line graph data is displayed on the rectangular coordinates of the display 3, as shown in FIG. 4(a). The base line graphs A, B, and C and the line cursor L are displayed in a superimposed manner (ST3°4).

Next, use the keyboard 5 to input the bias value of a predetermined line graph (B in this case) so that the overlapping portion of each line graph A-C is minimized (ST
5). Then, the bias value of the predetermined line graph B is updated (ST6), and the displayed image on the display 3 becomes as shown in FIG. 4(b). Also, using the auxiliary input device 6, a request to move the line cursor L is input so that the line cursor L is positioned at a location where the line graphs A to C do not overlap (ST7). Then, the position of the line cursor L is updated (ST8),
For example, it moves to the position shown at Ll in FIG. 4(C). In this state, when a graph identification mark display request is input using the auxiliary input device 6 (ST9), the line cursor L
1 and each line graph A-C to identify each line graph (for example, "
``O'', ``△'', ``mouth'') are displayed (ST10).

After that, repeat ST5 to 5T10 to create each line graph A.
-Move the line cursor to multiple parts L2゜L3 where C does not overlap, and move the line cursor and each line graph Q-
A graph identification mark is displayed at the intersection with C. After making it easy to identify each of the line graphs A to C displayed on the display 3 as shown in FIG. 4(d) in this way,
A copy request is input to the hard copy device 4 using the keyboard 5 (ST11). Then, the image data on the display 3 is copied by the hard copy device 4 (ST12).

In this way, according to this embodiment, when multiple line graphs overlap, the bias value of each line graph is changed to reduce the overlapping portion, and furthermore, each line graph is placed on an appropriate graph that does not overlap. Since the graph identification mark is displayed, a copy image in which the trajectory of each line graph can be easily identified can be obtained using the hard copy device 4 with a simple operation.

Note that the present invention is not limited to the above embodiments.

For example, in the above embodiment, a graph identification mark is displayed at the intersection of the line cursor L and each line graph A-C, but as shown in FIG.
A graph identification mark may be displayed corresponding to the intersection position. In this way, each line graph A
The operation of changing the bias value of -C can be omitted, and there is no fear that the trajectory of the graph will be difficult to understand due to the identification mark. In addition, Fig. 6(a) to (
Display rectangular coordinates for each line graph as shown in C),
A similar effect can be obtained by moving the line cursor simultaneously for each coordinate and displaying a graph identification mark at the intersection of the line cursor and the line graph. moreover,
The graph identification mark may be displayed not only as a symbol but also as a character as in this embodiment. Further, in the above embodiment, the keyboard 5 has the function of inputting a line graph display request and the function of inputting a copy request to the hard copy device 4, but the auxiliary input device 6 may also have these functions. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[8 Bright Effects] As detailed above, according to the present invention, a line cursor movable in the horizontal axis direction parallel to the vertical axis is displayed on the display unit that displays a plurality of line graphs on rectangular coordinates. Then, each line graph is identified based on the intersection of this line cursor and the plurality of line graphs, and the identified plurality of line graphs are copied by the copying unit. It is possible to provide a graphic device that can easily identify the locus of a graph when a plurality of line graphs are copied.
