Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graph distributed processing method, and particularly to a method for displaying a graph (such as a business graph) on a graphic display device of a workstation in an information processing system having a host computer and a workstation. This paper relates to a graph distributed processing method for drawing.

[Conventional technology]

Conventionally, an AP (Application
In the method in which a graph is drawn on a graphic display device on a workstation using the ion program (application program), the following processing is performed.

The AP is based on various numerical data, etc. (including data necessary for drawing graphs in which individual numerical data has been aggregated and sorted) and graph editing information indicating the graph format, layout, etc. Create a graph image using graphic display control code.

Next, the AP transmits the graph image to a predetermined workstation via a communication line (communication means), and draws a graph related to the graph image on the graphic display device on the workstation under direct control. do.

Here, the programmer who creates the AP that draws the graph as described above needs to understand the C0B, which is difficult to visually grasp the graph.
The AP had to be written in a programming language such as OL.

[Problem to be solved by the invention]

In the conventional method described above, it is necessary to write an AP that draws graphs using a programming language such as C0BOL, which is difficult to visually grasp graphs.
This has the disadvantage that the efficiency of creating P becomes poor.

In addition, since graphs are drawn on the graphic display device on the workstation under direct control from the AP on the host computer (originally, drawing graphs that should be done visually by Workstersion users, the AP The problem is that the workstation user cannot interactively edit (correct, etc.) the graph while viewing the graphic display device.

Furthermore, since the graph image based on the graphic display control code must be sent from the host computer to the workstation, the length of the message sent from the host computer to the workstation increases, resulting in poor communication efficiency.

In view of the above-mentioned points, an object of the present invention is to separate graph drawing processing from AP description and realize distributed processing related to graph drawing), and to improve efficiency and simplify creation of an AP related to graph drawing. A graph that enables workstation users to edit graphs interactively while viewing a graphic display device, and shortens the length of messages sent from the host computer to the workstation, improving communication efficiency. The object of the present invention is to provide a drawing processing method (graph distributed processing method).

[Means to solve the problem]

In the graph distributed processing method of the present invention, a host receives plotting data from an AP, optimizes the plotting data, starts a workstation graph utility, and sends graph data, which is optimized plotting data, to the workstation graph utility. A graph service subroutine on a computer receives graph data from the graph service subroutine, and displays the graph graphically based on either catalog information related to the graph drawn using the graph data or specified values of graph editing information related to the graph. The workstation graph utility on the workstation that draws the graph on the device, edits the graph in an interactive manner with the workstation user, and registers graph editing information that reflects the edited graph as new catalog information. and has.

[Effect]

In the graph distributed processing method of the present invention, the graph service subroutine on the host computer receives plotting data from the AP, optimizes the plotting data, starts the workstation graph utility, and uses the optimized plotting data for the workstation graph utility. When certain graph data is sent, the workstation graph utility on the workstation receives the graph data from the graph service subroutine, and either the catalog information related to the graph drawn by the graph data or the specified value of the graph editing information related to the graph Based on this, the graph is drawn on the graphic display device, the graph is edited in an interactive manner with the workstation user, and graph editing information reflecting the edited graph is registered as new catalog information.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the graph distributed processing method of the present invention. The graph distributed processing method of this embodiment includes a host computer 11, a communication means (communication line) 15, and a workstation 16.

The host computer 11 has a data file 12 and a

The workstation 16 includes a workstation graph utility 17, a catalog file 18, and a graphics display device 19.

Referring to FIG. 2, the processing of the graph distributed processing method of this embodiment includes a data manual step 21, a data addition step 22, a drawing data generation step 23, a drawing data acquisition step 24, and a drawing data optimization step. step 25, workstation control step 26, graph data sending step 27, graph data receiving step 28
, catalog information presence/absence determination step 29 , specified value manual step 30 , catalog information input template 31 , graph drawing step 32 , and editing request presence/absence determination step 3
3, a graph editing step 34, and a catalog information registration step 35.

Note that steps 21 to 23 are processes performed by the AP 13, and steps 24 to 27 are processes performed by the graph service subroutine 1.
Steps 128 to 35 are the processes and determinations performed by the workstation graph utility 17.

Next, the operation of the graph distributed processing method of this embodiment configured as described above will be explained.

The AP 13 written in a programming language such as C0BOL on the host computer 11 inputs data (numerical data) from the data file 12 in which various numerical data are stored (step 21), and inputs data for sorting, aggregation, etc. is processed (step 22), and plotting data representing data necessary for plotting (drawing) a graph in a predetermined format is generated in an information table (not shown) in memory (step 23).

The graph service subroutine 14 on the host computer 11 is called by the AP 13 when it is necessary to draw a graph during the process of the AP 13, and performs the following processing.

The drawing data generated in the information table in step 23 is acquired from the AP 13 (step 24), and the drawing data is processed (aggregation and counting of numerical data in the drawing data, etc.) and edited (numerical data necessary for drawing). digit alignment, etc.) (step 25).

Next, control is performed to start the workstation graph utility 17 on the workstation 16 (step 26), and the graph data, which is the drawing data optimized in step 25, is transmitted to the communication means 15 to the activated workstation graph utility 17. Send via (
Step 27).

The workstation graph utility 17 on the workstation 16 performs the following processing.

First, graph data is received from the graph service subroutine 14 via the communication means 15 (step 28).

Next, it is determined whether the catalog information @ (cataloged graph editing information related to the graph drawn using the graph data) has already been registered in the catalog file 18 (step 29).

If the catalog information is not registered in the catalog file 18 in this judgment, the default value of the graph editing information (the default value of the graph editing information set according to the type of graph) is manually set in step 30). , the graphic display device N19 draws the graph using the default values.
(Step 32).

If the catalog information is already registered in the catalog file 18 as determined in step 29, the catalog information is input (step 31), and the layout of the graph and the values of each part are determined based on the catalog information, and the graphic display device The graph is drawn for No. 19 (step 32).

Furthermore, in order to modify the graph in an interactive manner with the workstation user, the workstation user issues an editing request instructing the modification of the graph drawn on the graphic display device f19. (Step 33).

If it is determined that an editing request has been issued, the graph on the graphic display device 19 is edited based on the editing request (step 34).

Finally, update the graph editing information @ (default value of graph editing information or catalog information) input in step 30 or 31 to reflect the graph edited in step 34,
The updated graph editing information is registered in the catalog file 18 as new catalog information (step 35).
