Tool and Script to Plot Probe Values on a Graph

An interesting request came in today: Can I plot the values from my interactive query probe in a graph?

Good question. Currently, you can see the values reported next to the query probe in the viewport, and you can click on “display values” to get a window pop up with the values in tabular form. But, you can’t populate a Query for a Plotter and get a graph of the values.

Python to the rescue again. Through python, you have direct access to a list of those Interactive Probe Queries and their values. With that information, we can utilize Python to populate those values into a Query Register and make a Plotter (or graph) of them.

This small Python macro will create 4 queries actually: one for X coordinate vs Variable; one for Y coordinate vs. Variable, one for Z Coordinate vs. Variable; and one of Distance (from first probe) vs. Variable. The default plot is chosen as “Distance Vs. Variable”. However, the user can easily drag any of the other 3 queries into the plotter (or make their own plotter) in EnSight. Here is what it looks like when I have 6 probe values:

You can see that you have 4 queries generated, and 1 plotter.

Download the following python and setup as a macro perhaps (assign it to a memorable keystroke sequence) and be able to quickly and easily plot the values from your multiple interactive probes…. Voila.

Another option is a python tool that will do this.
