Code and Documents



This VI shows how to use and to programmatically modify multiples Y scales.



This VI could be used to programmatically modify waveform chart multiples Y scales using two property nodes.

The property node used are "ActY Scale" and "Y Scale Maximum", the first one is used to select on which scale operate while the second one is used to change the maximum Y value.



  • LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Run VI
2. Look at graph scales

Nice VI, thank you!

Just connect the error reference of the property nodes to achieve a good setting in the graphic.
