Abstract

PROBLEM TO BE SOLVED: To eliminate the overlapping of item names displayed on the X axis in the case of displaying a graphics by deciding the arrangement of the item names whose overlapped indication is to be eliminated when the overlapping of display of the drawn item names takes place and revising the display arrangement of the item names based on the arrangement. SOLUTION: A control means 11 allows a character string check means 6 to check an overlapping degree of an X axis item name character string based on data from a graphic data entry means 5. The character string check means 6 extracts data of the item name added to the X axis required for graphic display among the data to check the overlapping off character strings. A display method decision means 7 decides whether the character string of the item names is to be displayed in a single lateral way, in the indication of plural lateral strings, in longitudinal indication or in skip indication based on the check result. An item name generating means 8 revises the arrangement of the item names according to the display method. Thus, the overlapping of the item names displayed on the X axis in the case of graphics display.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing the configuration of an embodiment of the present invention, a graph generating apparatus 1 includes an input device 2 for inputting data for drawing a graph, an output device 3 for displaying and outputting a graph, and an X-axis. Graph generation unit 4 that optimally displays the item names of
And, including. The graph generator 4 controls the operation of the graph generator 4 according to a graph output instruction from the user, and the graph data input device 5 receives data from the input device 2.
Then, from the data, character string check means 6 for extracting the data of the item name to be added to the X-axis necessary for the graph display and checking the overlapping of the character strings, and the item name of the item name based on the check result. Display method determining means 7 for determining whether the character string is displayed in a single horizontal display mode, a plurality of horizontal display modes, a vertical display mode, or a skip display mode, and the arrangement of item names is changed according to the display method. Item name generating means 8, a graph image generating means 9 for generating a graph image based on the changed array item names and unit data, and a graph image outputting means 10 for outputting the graph image to the output device 3.
And. The output device 3 receives the graph image from the graph image output means 10 and outputs the graph displayed on the screen.

Next, the operation of this embodiment will be described.

Referring to FIG. 2 showing the flow of operation of the control means 11, first, the control means 11 causes the graph data input means to acquire data for graph output (step 2).
1) Based on the data, the character string checking means 6 is caused to check the degree of overlap of the X-axis item name character strings (step 22). The control means 11 causes the display method determination means 7 to determine the display method based on the result (step 23).
According to the determined display method, the control means 11 causes the item name generation means 8 to change the X-axis item name character string array (step 24) and causes the graph image generation means 9 to generate a graph image (step 25). Further, the graph image output means 10 causes the output device 3 to display and output the graph image (step 26).

Next, referring to FIG. 3 showing a flow of the operation of the character string checking means 6 for checking the overlapping condition of the X-axis item name character strings, the character string checking means 6 indicates the X of the graph.
The area allocation size per item name is calculated based on the drawing area size of the axis (step 31), the size and the number of characters of the item name are compared for all the item names (step 32), and all the item names are drawn. When the size fits within the allocated size, the overlap flag is set to 0, and the process ends (step 3
3), if one of the item names does not fit in the allocated size (NO in step 33), the area size that can display all the item names on the X axis is calculated (step 3).
4) Then, the overlap flag is set to 1 and the process ends.

Further, referring to FIG. 4 showing the operation flow of the display method determining means 7 for determining the display method, if the result of the character string check is that the overlap flag is 0 (step 41).
YES) The display method is determined to be single horizontal display (step 4
2) If the overlap flag is not 0 (N in step 41)
O), if the area size for drawing all the item names is less than twice the drawing allocation area (YES in step 43),
The display method is determined to be two-stage horizontal display (step 44), and if it is less than 3 times (YES in step 45), the display method is set to 3
If horizontal display is determined (step 46), and the display method is less than 4 times (YES in step 47), the display method is determined to be four horizontal display (step 48), and if it is less than 5 times (step 4).
(YES of 9), the display method is determined to be a 5-step horizontal display (step 50). If the drawing allocation area is five times or more, or if the area size required for the number of X-axis items x 1 character display is smaller than the drawing allocation area (YES in step 51), the display method is determined to be vertical display (step 52). If it cannot be displayed even in the vertical display (NO in step 51), the item names are thinned out and the skipped display with a space is determined (step 53).
The process ends.

[0013]
