Description

[Detailed Description of the Invention] [Summary] The present invention is a method for arranging a graphic element connection diagram consisting of graphic elements (symbols) and connection lines connecting them, and an input graphic element connection in which symbols are manually arranged. By rearranging input graphical element connection diagrams so as to focus on and align specific symbols in the diagram, the entire diagram is made easier to see without destroying the original image of the diagram.

[Industrial application field]

The present invention relates to a graphical element connection diagram arrangement method, and in particular, by arranging predetermined symbols and connection lines connecting them on a display screen, state transition diagrams, flowcharts, block diagrams, etc. are inputted. In the figure editing system to be edited,
This relates to an arrangement method for arranging symbols.

If you create a connected figure element diagram using the figure editing system mentioned above, if you enter or edit the drawing manually, the positions of each symbol may not be aligned, resulting in a drawing that is difficult to read. A function to rearrange symbols for easy viewing is required.

[Conventional technology]

Conventionally, as a method for automatically arranging symbols of graphical element connection diagrams, for example, the applicant of the present invention first proposed Japanese Patent Application No.
The automatic arrangement method disclosed in No. 17 is known.

This state transition diagram automatic arrangement method proposed by the present applicant is a graphic editing system that creates drawing data from data representing connection relationships between symbols. It consists of an arrangement section and an other symbol arrangement section that arranges each symbol other than the state symbol, and a law that determines the position at which a symbol representing a state should be arranged is determined in advance, and the state symbols are connected from the initial state. A level is determined for each state symbol according to the order, and a sublevel is determined according to the situation in which lower state symbols are to be connected between state symbols of the same level, and according to the above level and sublevel. The position of the state symbols is determined and placed according to the above rules, and when all the state symbols have been placed, the graphic data of the state transition diagram is created by placing the symbols between the state symbols. It is.

According to the method proposed by the present applicant, from state transition diagram data consisting only of symbol connection information without position information,
It is possible to automatically determine the placement of each symbol and create a drawing.

(Problems to be Solved by the Invention) According to the above-mentioned method proposed by the applicant, when automatically arranging symbols, the positional information originally possessed by the symbols is not taken into consideration, and the connection relationships between symbols, etc. Since the placement position of the symbol was determined solely by the method, the image of the original drawing was completely changed, and the problem was that it could become difficult to understand.

The present invention was created in view of the above points, and an object thereof is to provide a graphic element connection amount arrangement method that allows easy-to-read symbols to be arranged without damaging the image of the original drawing. .

[Means for solving problems]

FIG. 1 shows a basic configuration diagram of the present invention. The present invention provides a reference symbol selection unit in a graphic element connection amount arrangement method that generates drawing data (7) for determining the arrangement position of each symbol in a graphic element connection diagram from symbol data 1 having position information of symbols that are graphic elements. 2. Column determining unit 3, row determining unit 4
, a reference symbol arrangement section a 5 and an other symbol arrangement section 6.

The reference symbol selection unit 2 selects a specific type of symbol, which serves as a reference for arrangement, from the symbol data 1 as a reference symbol. The column determining unit 3 and the row determining unit 4 determine the columns to be arranged for each reference symbol at the back of each column and each row, which are divided into fixed widths in the vertical and horizontal directions of the graphic element connection diagram. and rows respectively.

The reference symbol arrangement unit 5 determines the arrangement position d of the reference symbol, and the other symbol arrangement unit 6 arranges the arrangement position of the square symbol between 19 symbols based on the data of symbols other than the reference symbol in the symbol data 1. stipulated in

[Effect]

The reference symbol extracted from the symbol data 1 by the reference symbol selection unit 2 has a column determining unit 3 determining the column in which it should be arranged, and a row determining unit 4 determining the row in which it should be arranged. Once the columns to be arranged and the rows to be arranged are determined in this way, the reference symbol arrangement section 5 determines the arrangement position of each reference symbol in the graphic element connection diagram based on these.

Further, other symbols are determined by the other symbol arrangement unit 6 to be located at positions that match or are extremely similar to the position information of the other symbols, and to be located at positions between the reference symbols.

In this manner, according to the present invention, after determining the area in which the reference symbol should be placed based on the position information that the reference symbol has in advance, out of the grid-like placement area defined by the rows and columns, other symbols can also be placed. Since the symbols are arranged in any of the grid-like arrangement areas between the reference symbols based on the position information they have in advance, the symbols are aligned in the vertical and horizontal directions.

〔Example〕

The operation of one embodiment of the present invention will be explained with reference to FIGS. 2 to 6. Now, let us assume that the graphic element connection diagram input manually is as shown in FIG. 2, and we will explain the case where this is rearranged according to the present invention. In FIG. 2, S- is a symbol representing a state, EV is a symbol representing an event, DE is a symbol representing a decision,
OtJ is a symbol representing output, TA
is a symbol that represents a task, and EX is a symbol that represents an exit (
CN is a symbol that represents a connector (con
This is a symbol representing ``nector''.

As shown in FIG. 2, in the subsequent graphic element connection diagram, the positions of the state symbols ST, which are main symbols, are not aligned with each other.

FIG. 3 shows the main part of the symbol data of each symbol constituting the graphic element connection diagram of FIG. 2. As shown in Figure 3,
The symbol data consists of the symbol type and the position coordinates (x, y) of the symbol, and the position coordinates (x, y) represent the position where the symbol is to be placed.

Based on this symbol data, the reference symbol selection section 2 extracts, for example, a state symbol ST as a reference symbol. The reference symbol selection unit 2 selects and extracts all of the state symbols ST+ to ST6 in FIG. 2 from the symbol data as reference symbols as shown in FIG. 4 (A>).

Next, the column determining unit 3 uses the above state symbols ST+ to ST6.
are arranged in ascending order with respect to the
The state symbols in the same divided area are grouped together to determine the column to be arranged as shown in FIG. 4(B).

On the other hand, the row determining unit 4 uses the above state symbols ST+ to STe.
are arranged in ascending order with respect to the
The rows to be arranged as shown in Figure (C) are determined.

Next, the reference symbol placement unit 5 determines common elements in each column and each row based on the column data obtained by the column determination unit 3 and the row data obtained by the row determination unit 4, and calculates common elements for each reference symbol. Columns and two rows of are determined as shown in FIG. As shown in Figure 5, the status symbol (here, the reference symbol)

Since ST2 and STa are in the same row, they are arranged in a straight line in the vertical direction in the drawing, and similarly ST4 and ST
Since s is also in another same column, they are arranged in a straight line in the vertical direction. Also, since the state symbols ST+ and ST4 are on the same row, they are arranged on a horizontal line in the drawing, and the state symbols ST2 . ST5 and STa are also arranged on another horizontal line.

Next, the state symbol ST

As a result, according to this embodiment, the symbols in the input graphic element connection diagram shown in FIG. 2 are rearranged as shown in FIG. 6. As can be seen from FIG. 6, the status symbols, which are reference symbols, are arranged in alignment, and the other symbols between them are also arranged in alignment, so that the entire drawing is neatly organized and easy to see.

〔Effect of the invention〕

As described above, according to the present invention, each symbol is arranged so as to be aligned by simply slightly moving it based on the positional information that each symbol has in advance, so that the image of the original input graphical element connection diagram is not destroyed. This feature has the advantage that the entire drawing can be arranged in an orderly manner without any confusion, and therefore the entire drawing can be easily viewed and each symbol can be neatly arranged.
