Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a display/7 stem that displays a graph on the display based on a specified menu and data, and when there is a specification for reversing the graph, Coordinates are calculated in the processing program using a virtual coordinate system, and the pattern is reversed to create hardware order data for display, and the text is displayed in relative positions such as above, below, and to the top right of the text column. This invention relates to a graph reversal processing method for display display in which a position is specified.

[Prior art and problems]

FIG. 1 is a diagram showing an outline of a processing section for displaying a graph on a display, and FIG. 2 is a diagram showing a normal display and an inverted display of the graph. In FIG. 1, 1 is a control unit, 2 is a processing program, 3 is a hardware order data creation unit, 4 is a hardware order data storage unit, and 5 is a display output control unit.

Reference numeral 6 indicates a display, and 7 and 8 indicate external storage devices.When a graph is to be displayed on the display, a menu is first displayed on the display.

In the menu, for example, do you want the graph to be a bar graph?
Alternatively, there are options for specifying the graph, such as pie chart, line graph, bar O line graph, composition ratio graph, histogram, etc., as well as the color of the graph line, the color of each character, the display unit, etc. There are a lot of items on the menu, even small pieces. When the displayed menu is specified, a graph is created using the given data according to the specified contents,
displayed on the display. FIG. 1 shows an overview of the processing section that performs the processing. In FIG.

The external storage devices 7 and 8 store display data, graph Φ patterns, processing programs, etc., and are read into the control unit 1 as appropriate. The control section 1 displays a menu on the display 6 using the display output control section 5, and when each item of the menu is designated 1, the processing program 2 is operated according to the menu. The processing program 2 calculates the coordinates, and the noheidware order data creation section 3 creates characters and circles.

Nodeware order data for displaying graphs such as lines is created. The hardware order data is stored in the hardware order data storage section 4 and displayed on the display 6 through the display output control section 5. However, as shown in Figure 2 (α), 1
Not only when a digraph is displayed in the normal display format, but also when a reverse display is specified as shown in Figure 2 (h). )and(
As is clear from a comparison with (b), the Y-axis and Y-axis are swapped, the screen of the display 6 is longer horizontally, and the ratio of the display unit length of each coordinate axis is changed. For this reason, in the processing program 2, when calculating coordinates, it is necessary to always be aware of whether or not to perform inverted display as shown in FIG. 2<b>.

In particular, text reversal processing is complicated because the height of the text string must be considered in order to maintain the directionality of the text. hand.

When reversal is specified, the display position of the text is automatically adjusted, and the ninth coordinate calculation process for reversal is concentrated to simplify the processing program. The purpose is to provide a method.

[Structure of the invention]

To this end, the graph reversal processing method for display display of the present invention calculates coordinates based on the specified menu and data, creates lines and text for the graph to be displayed, and displays the graph on the display. In a display system that performs graph inversion processing, a virtual coordinate system setting means that sets a virtual coordinate system corresponding to the inverted coordinate system in a pattern in a normal display format; and a coordinate conversion means for converting into a coordinate system, and when the specified menu specifies to invert the graph, the virtual coordinate system setting means sets the virtual coordinate system and calculates the coordinates, Thereafter, the coordinates are converted to an inverted coordinate system by the coordinate conversion means to create graph lines, text, etc. to be displayed on the display, and the coordinates to be displayed in the text string specify the relative position of the text string and are inverted. This feature is characterized in that when the specified text string is specified, the relative position of the specified text string is moved.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a diagram showing the relative positions of text strings to which the present invention is applied, FIG. 4 is a diagram showing the relative positions of text strings in normal display and reverse display, and FIG. 5 is a diagram showing virtual coordinates to which the present invention is applied. FIG. 6 is a diagram illustrating the concept of a processing unit to which the present invention is applied. In FIG. 6, the same symbol as in FIG. 1 indicates the same thing as in FIG. 1, and 9 indicates a reversal subroutine.

The reversal process when displaying text will be explained with reference to FIGS. 3 and 4. In the present invention, when displaying text, the X and Y coordinates on the graph screen and the relative position of the text string that the coordinates mean are specified. That is, the relative positions of the text string include, for example, as shown in FIG. 3, the upper left, left, lower left, top,
These include middle, bottom, top right, right, bottom right, etc. When performing the reversal process, as shown in FIG. 4, the relative position shown in FIG. 3 can be shifted clockwise by two positions to complete the designation. The relative position of the text string shown in Figure 4 (α) is at the bottom, but if there is a reversal specification, the text string is shifted two positions clockwise from the bottom to the left, as shown in Figure 4 (b). Specifies the relative position of the text column. Therefore, for example, if the relative position of the text string is specified at the bottom left in FIG. 4(α), the relative position of the text string will be specified at the top left in FIG. Become.

The reversal process of coordinate calculation will be explained with reference to FIG. FIG. 5<a) shows the coordinate system of the graph before reversal. In the menu specified for displaying a graph, there is a menu that specifies the display range of the graph, and if you follow the specified display range, it will normally be displayed as shown in Figure 5 (,). . However, if there is a designation for reversal, the display will be as shown in FIG. 5(1). Therefore, although a virtual coordinate system is set as shown in FIG. 5(b) in which the coordinates can be uniformly mechanically converted to the coordinates shown in FIG. 5(6) after this reversal, this virtual coordinate system is By correcting the Y-axis of the coordinates and the ratio of the Y-axis using the pattern in the normal display format shown in FIG. 5(α), the setting can be performed with a relatively simple process.

All processing programs perform coordinate calculations using this virtual coordinate system. The present invention, together with a means for setting such a virtual coordinate system, converts the coordinates of n7 calculated in the virtual coordinate system shown in FIG. 5(b) into an inverted coordinate system as shown in FIG. 5(6). A means is provided to do so. As a result, the processing program can process the inversion table in the same pattern as the normal display format even when the table is inverted in red, and there is no need to make the processing program aware of the inversion. FIG. 6 shows an example in which a temporary coordinate system setting means and a means for converting coordinates into an inverted coordinate system are implemented by providing dedicated subroutines. In this way, by concentrating the virtual coordinate system setting process and the inverted coordinate conversion process in the dedicated inversion subroutine 9, the processing program does not need to be conscious of inversion, so the processing program can be simplified. .

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, since the display position of the text string is specified using the relative position of the text string, it becomes easy to reverse the text string, and when the text string is not reversed, Since the coordinates of the reversed graph are calculated through a virtual coordinate system with the same pattern as that of . Therefore, it is possible to increase the processing speed and improve the performance of the apparatus.
