In order to specify the route corresponding to the graph horizontal axis display order 85 that defines the display order on the graph horizontal axis 12, the display horizontal path order specification data input unit 40 of the horizontal axis information generation unit 20 sets the graph horizontal axis information 23. The route number 81 is interactively input as an identification number, and graph horizontal axis / route number correspondence data 84 composed of the horizontal axis number 85 and the route number 86 is generated. Next, the display route order change processing unit 182 of the graph horizontal axis information generation means 20 causes the graph horizontal axis / route number correspondence data 8 to be displayed.
The graph horizontal axis information 23 is regenerated as specified in 4.

Therefore, the display order on the graph horizontal axis of a plurality of routes displayed on the graph can be freely changed, and by defining the graph horizontal axis 12 closer to the main route axis 5 as a more important route, It is possible to arbitrarily weight each route on the display. First of this invention
FIG. 1 shows a network data display device according to a fifth embodiment.
This will be described with reference to FIGS. 6 and 7. 1, 6 and 7 are the same as those of the seventh embodiment. That is, the graph horizontal axis information generation unit 20 displays the graph horizontal axis information 23 that defines the expression of the graph horizontal axis 12 described in the first embodiment after inputting the graph described in the horizontal graph axis information 23. In the node number column 82 on the route, the graph horizontal axis 12
Node 1 displayed or not displayed on the network 1
Interactively input in the above route unit or node unit, and output the designated result to the graph horizontal axis information 23 as a node number sequence 82 on each route. Further, the network data display means 27 inputs the graph horizontal axis information 23 and the node data on the network 1, and is a main route on the network 1 constituted by the nodes 2 and the branch 13 and a branch route 4 from the main route 3. Of the graph horizontal axis information 2
A branch of the network 1 for the route and the node 2 described so as to be displayed as a graph in the node number column 82 of 3
The node numbers of the nodes on the network 1 are graduated and displayed on the graph horizontal axis 12 represented so that the connection and the form match, and at the same time, the graph horizontal axis information 23 of the node data on the network 1 is displayed. The node data connection line 8 that is connected according to the network connection state for the paths and nodes described in the node number column 82 as a graph is displayed.

Specifically, first, the graph horizontal axis information 23 including the horizontal axis number 87, the path number 81, and the on-route node number sequence 82 is interactively displayed by the graph horizontal axis information input unit 21 of the graph horizontal axis information generating means 20. It is assumed that the horizontal axis representation determining unit 181 of the graph horizontal axis information generating unit 20 has input the data or generated the network information 31 or the like. Next, the hidden node number deleting unit 1 of the graph horizontal axis information generating means 20.
Reference numeral 85 allows the operator to refer to the contents after inputting the graph horizontal axis information 23. Based on the contents referred to by the operator, the operator displays the non-display route of the graph horizontal axis information generating means 20 and the node designation data input unit 45. Thus, among the routes described in the graph horizontal axis information 23, a route which is not desired to be displayed as a graph is interactively input with the route number 81 of the graph horizontal axis information 23 as an identification number, and the non-display route number data 88 is generated. Further, a node number that is not desired to be displayed in the graph is interactively input in the on-route node number sequence 82 described in the graph horizontal axis information 23, and the hidden node number data 90 is generated. Next, the non-display node number deleting unit 185 of the graph horizontal axis information generating means 20 inputs the non-display route number data 88, and if the value is "2", for example, it is displayed as the graph horizontal axis information 23 at that time. The target node on the route with the route number “2” is not displayed in the graph, and only the remaining nodes on the route with the route numbers “1” and “3” are displayed in the graph. Further, the hidden node number deletion unit 185 inputs the hidden node number data 90, and if the value is “50”, for example, the route node that is the display target in the graph horizontal axis information 23 at that time. The graph horizontal axis information 23 defining the expression of the graph horizontal axis according to claim 1 for displaying a graph other than the node number of “50” in the number string 82 is updated and generated.
However, when the node having the value of the on-route node number column 82 is a branch node, it is excluded from the above processing targets. Next, the graph drawing data generation / editing / outputting unit 25 of the network data display means 27 inputs the graph horizontal axis information 23 and the network data 24, and outputs the network data in the same manner as described in the seventh embodiment. The graph is displayed and output on the display device 26.

Therefore, in the graph display of the first embodiment, it is possible to eliminate unnecessary display of nodes of little interest on the displayed graph and improve the visibility of the graph. A network data display device according to a sixteenth embodiment of the present invention will be described with reference to FIGS. 1, 6 and 7. 1 (a), 6 and 7 are the first
0 is the same as the embodiment. In the sixteenth embodiment, a numerical value for logically classifying the node 2 displayed on the graph horizontal axis 12 and the hidden node 2 by the node number of the node 2 on the network 1 is input, Network 1 based on numerical values and predetermined numerical formulas
A graph horizontal axis information generation means 20 having a function of determining whether each of the above nodes 2 is a node to be displayed and outputting only the information to be displayed in the graph to the graph horizontal axis information is provided. The graph horizontal axis information generation means 20 interactively inputs a numerical value for numerically classifying the node 2 displayed on the graph and the hidden node 2 by the node number of the node on the network 1, and the numerical value and the value in advance are input. It is determined whether or not each node 2 on the network 1 is a node to be displayed from the determined numerical formula, and as a result of the determination, a node number string consisting only of the node numbers to be displayed in the graph is output to the graph horizontal axis information 23. . Further, the network data display means 27 inputs the graph information and the node data on the network 1, and among the main route 3 and the branch route 4 from the main route 3 on the network 1 constituted by the nodes 2 and the branch 13, The path and node described to be displayed in the graph in the node number column of the graph horizontal axis information 23 are represented so as to match the branching / connection of the network 1 and the form. Display the node numbers arranged on a scale,
At the same time, of the node data on the network 1, the node data connecting line 8 that connects the paths and the nodes described so as to be displayed as a graph in the node number column 82 of the graph horizontal axis information 23 in accordance with the network connection state.
Is displayed.

More specifically, first, the network information input means 30 is required to connect the nodes 2 and branches 13 constituting the network 1, the node (0) which is the node number of the starting point node for starting the data display, and the necessity. Accordingly, the network information 31 is generated by interactively inputting the node (40), which is the node number of the end node of the data display (not required in the example).

By the display node classification designation data input unit 46 of the graph horizontal axis information generating means 20, among the nodes 2 on the network 1 to be displayed on the graph, the nodes to be displayed on the graph and the nodes not to be displayed on the network 1 are displayed.

A node number string 82 consisting only of node numbers of nodes and a route number 81 of a route having a node number to be displayed on the branch route axis 7 are output to the graph horizontal axis information 23. As an example, when the numerical value “70” is used as the display node classification data 92, and the content of the numerical formula stipulates that a node having a node number greater than or equal to the display node classification data 92 is not displayed, the hidden node determination unit 186 determines that among the nodes on the network 1, only the node (70) is not displayed, and when the node (70) is not displayed, there is no node to be displayed on the horizontal axis of the third graph. On-path node number sequence 82 is (0), (10), (20), (30)
And a route consisting of (40) and a node number sequence 8 on the route
2 outputs the route number 81 and the on-route node number sequence 82 of the route of (0), (10), (50) and (60) to the graph horizontal axis information 23. Next, the graph drawing data generation / editing / outputting unit 25 of the network data display means 27 inputs the graph horizontal axis information 23 and the network data 24, and outputs the network data in the same manner as described in the seventh embodiment. The graph is displayed and output on the display device 26. Therefore, when the operator inputs the network information 31, it only has to consider how to assign the node numbers to the nodes that do not need to be displayed in the graph in advance, so that the operator can select the displayed nodes on the graph as in the case of the fifteenth embodiment. In the graph display of the first embodiment, it is possible to eliminate unnecessary display of nodes of little interest on the graph to be displayed and improve the visibility of the graph.
