Abstract

PURPOSE:To obtain easy-to-see display such as a flowchart with simple constitution by calculating the number of characters, which can be displayed, in a displayed figure symbol, and displaying a label consisting of the small number of characters when a text character string exceeds the calculated number. CONSTITUTION:Display data such as figure symbol data and text character strings, which a producer inputs from an input part 1, are stored in a display data storage part 2. A figure symbol extractor 4 and a text character string extractor 7 extract figure symbol data and text character strings. A permissible character frequency decision part 6 decides the number of permissible characters, and a character frequency comparator 9 compares it with the number of characters recognized by a character frequency recognition part 8. When the decided frequency exceeds the latter frequency, text character strings are transmitted to a label affixing part 11. Then, the initial label, which is stored in a label control data storage part 12, is affixed, and an address of the text character strings is stored in the corresponding location of said storage part 12. A display controller 5 displays a figure symbol on a display 10, and displays a label on the symbol instead of the text character strings.

Description

[Detailed Description of the Invention] +a) Technical Field of the Invention The present invention relates to a graphic display system, and particularly to a character display control method that allows easy-to-read flowcharts and the like to be displayed.

(b) Background of the Technology Automatic program creation systems are being put into practical use for the purpose of reducing the man-hours required to create programs for electronic exchanges, electronic computers, etc. In this type of automatic program creation system, the creator sequentially inputs data showing the processing steps to be executed by the program to be created into the graphical display system in a predetermined format, thereby displaying a flowchart showing the processing steps of the program. A graphical display system is used that displays on the screen. In such a graphical display system, a creator inputs graphical symbol data indicating the processing format in each process and a text character string indicating the processing content, so that the graphical symbol data is displayed at a predetermined position on the display screen. A graphical symbol is displayed and a corresponding text string is displayed within the graphical symbol.

(C) Prior Art and Problems FIG. 1 is a diagram showing an example of a flowchart displayed by a conventional graphic display system. In FIG. 1, steps S1 to Sll are graphical symbols indicating the processing format of each process [for example, steps S1, S3, S5 and S8 are state i (STATE), steps S2, S6 and 3 are
11 is signal reception - (SIGNAL RECEIVE)
, step S7 is the signal transmission (SIGNAL 5END
), and steps S9 and SlO are the operation (OPER
] is displayed, and a text character string indicating the processing content is displayed within each graphic symbol. The size of each graphic symbol is determined in advance by the creator or based on the number of graphic symbols to be displayed on one screen, for convenience (hereinafter, the determined size will be referred to as mesh size). As is clear from FIG. 1, in conventional graphic display systems, regardless of the number of characters constituting a text character string, it is attempted to display the text within a corresponding graphic symbol. Therefore, text strings with a large number of characters, such as in steps S2 to S5, steps S9 and 310, cannot be accommodated in the corresponding graphic symbols, and furthermore, they overlap with adjacent graphic symbols, resulting in inconveniences such as difficulty in viewing. Ta. Although it has been considered to make the mesh size of each graphic symbol variable depending on the number of characters in the corresponding text string, this would require the graphic display system to be equipped with a complex display processing function, making it impractical.

(dl) OBJECTS OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the conventional character display control methods as described above, and to realize a means that enables a graphic display system to display easy-to-read flowcharts and the like.

(el) Structure of the Invention The object of the present invention is to provide a means for calculating the permissible number of characters that can be displayed in a graphic symbol to be displayed in a graphic display system that displays a plurality of graphic symbols containing text character strings within one screen; means for comparing the number of characters constituting a text string to be displayed in the graphic symbol with the permissible number of characters; means for adding an identification code to the text string consisting of a number of characters exceeding the permissible number of characters; This is accomplished by providing means for displaying an identification code and the corresponding text string, and displaying the identification code within the graphical symbol.

That is, in the present invention, when a text string cannot be accommodated in a corresponding graphic symbol, an identification code (hereinafter referred to as a label) consisting of a small number of characters added to the text string is Flowcharts etc. become easier to see by displaying them instead.

Further, the text string and the corresponding label can be displayed separately from the flowchart or the like.

(f) Examples of the invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing a character display control method according to an embodiment of the present invention, and FIG. 3 is a diagram showing an example of a flowchart displayed by FIG. 2. Note that the same reference numerals refer to the same objects throughout the plan. In FIG. 2, display data such as graphic symbol data and text character strings corresponding to each processing process inputted by the creator from the input unit 1 are stored in a display data storage unit 2. On the other hand, the mesh size determination unit 3 determines the mesh size based on a designation from the generation data or the number of graphic symbols to be displayed within one screen. In this state, the graphic symbol extraction section 4 extracts the graphic symbol data [STATE] corresponding to step S1 from the display data storage section 2, and transmits it to the display control section 5 and the allowable character number determining section 6. The allowable number of characters determining section 6 determines the number of characters that can be displayed in one line from the mesh size determined by the mesh size determining section 3, and also determines the number of lines that can be displayed within the graphic symbol based on the graphic symbol notified from the graphic symbol extracting section 4. By doing so,
Determine the allowable number of characters that can be displayed within the graphical symbol.

Further, the text character string extraction unit 7 extracts the text character string [TALK (C)] corresponding to step Sl. The character number identifying section 8 identifies that the text string extracted by the text string extracting section 7 is composed of seven characters. The character number comparing section 9 compares the number of characters identified by the character number identifying section 8 with the allowable number of characters determined by the allowable character number determining section 6, and if it identifies that the number is less than the allowable number of characters, it transmits the text string to the display control section 5. The display control unit 5 is a display 10
Graphical symbols are displayed at predetermined positions on both sides, and text strings are displayed within the graphical symbols. Next, the graphic symbol extraction section 4 and the text character string extraction section 7 perform step s.
Graphic symbol data corresponding to 2 [signal reception (SIGN
AL RECEIVE)) and text string [A:W
When extracting KUP (CMPO, B)),
As in step S1, the allowable character number determining unit 6 determines the allowable character number, and the character number identifying unit 8 identifies the number of characters constituting the text string as twelve. Further, the character number comparison section 9 compares the number of characters identified by the character number identification section 8 with the allowable number of characters determined by the allowable character number determination section 6, and when it is determined that the number of characters exceeds the allowable number of characters, transmits the text string to the display control section 5. It is transmitted to the Rahel applying section 11 without any problem. The label display unit 11 adds the first label (consisting of a label display column and a number indicating the order) stored in the label management data storage unit 12 to the text string transmitted from the character count comparison unit 9. Ll is added and transmitted to the display control section 5, and the address of the text character string in the display data storage section 2 is stored in the label L1 corresponding section of the label management data storage section 12. The display control unit 5 displays a graphic symbol at a predetermined position on the screen of the display 19, and also displays a label L1 in the graphic symbol instead of a text character string.
Display. Thereafter, in the same manner, the graphic symbol extraction section 4 and the text string extraction section 7 sequentially extract the graphic symbols and text strings corresponding to steps S3 and subsequent steps from the display data storage section 2, and the number of characters constituting the text string is If the number of characters that can be displayed within the graphic symbol is less than or equal to the allowable number of characters (steps S6, S7, S8, and 5ll), the text string is displayed within the graphic symbol, and the number of characters that make up the text string is within the graphic symbol. exceeds the allowable number of characters that can be displayed (steps S3, S4,
In S5 and S9, the labels L2 to L6 given to the text character strings are displayed within the graphic symbol. In addition, in the label management data storage section 12, each /'7 bell L
Steps S3, S4, S5, S9 corresponding to 2 to L6
and the address in the display data storage unit 2 of the text string corresponding to SIO is stored. As a result, as shown in FIG.
A flowchart in which L6 to L6 are reliably accommodated is displayed. Note that if the creator inputs a predetermined command from the input unit 1 requesting the display of a text string to which the label LL is attached, the label display unit 13 refers to the label management data storage unit 12 and displays the text corresponding to the label L1. extracts the address of the text string stored in the text string, and extracts the text string [A: WKUP (CMI) 0
．． B)) is extracted and transmitted to the display control unit 5 along with the label L1. The display control unit 5 displays the label L1 and the text string at a predetermined position on the screen of the display 10. Note that when the creator inputs a predetermined command requesting the display of all labels, the label display section 13 displays all the labels.
The display control unit bk displays text character strings corresponding to L6.
7+- and display on the display 11410 screen.

As is clear from the above description, according to this embodiment, when displaying the text strings corresponding to each step S1 to 311, the number of characters constituting each text string is compared with the allowable number of characters of the corresponding graphic symbol. However, if the allowable number of characters is exceeded, labels L1 to L6 consisting of a small number of characters are displayed instead, so as shown in Figure 1, the text string cannot be accommodated in the graphic symbol, and even the adjacent Overlapping text strings are reliably prevented and an easy-to-read flowchart is displayed. Note that the correspondence between labels 1 to L6 and text character strings can be displayed at any time.

It should be noted that FIGS. 2 and 3 are only one embodiment of the present invention, and the display target is not limited to the flowchart as shown, and many other modifications may be considered. In either case, the effects of the present invention remain the same. Further, the configuration of the graphic display system is not limited to that shown in the drawings, and many other modifications may be considered, but the effects of the present invention will not change in any case.

(g) Effects of the Invention According to the present invention, the graphic display system can display easy-to-read flowcharts, etc. without having to have a complicated display processing function, improving convenience for the creator and reducing errors. do.
