Graphing Shortest Paths
You can compute the shortest distance between two selected nodes on a graph and then examine the available scalar values within that interval. Results can be exported in the comma-separated values file (*.CSV extension) format.
Choose Utilities > Graph Shortest Path on the menu bar to open the Graph Shortest Path dialog, shown below.

How to Graph a Shortest Path
- Pick a path-starting vertex and a path-ending vertex with the Pick
tool. - Choose a measurement in the Edge measurement drop-down menu.
- Click the Compute path button.
- The shortest path between the selected vertices is computed automatically and the Edge LUT measurement is updated to highlight the computed path, as shown below.
In addition, specific measurements extracted from the edges within the path appear in the Graph Shortest Path dialog. These include the total of the selected measurements, the minimum, maximum, and mean values, as well as the variance.
- Add graph additional paths, if required.
To graph an additional path, pick new Start and End Indexes as required and then click the Compute path button.
- If available, you can choose other edge measurements for a path in the Current slot drop-down menu, as shown below.
- Export your results to a comma-separated values (*.CSV extension) file, if required.
To export your results to CSV, click the Export
button.
