How to Change Waveform Charts’ Scales Programmatically In LabVIEW

First, disable auto-scaling property of the waveform chart by editing Chart Properties Scales->Y-Axis and the uncheck Autoscale ;

Then, in the VI’s diagram, use property Y Scale –> Range –> Maximum and Minimum.  We can change these values in program and by this way, we can change waveform chart’s scales during runtime.

It doesn`t work for an input signal witch changes in time very fast.

@Tecu,
Yes, it doesn’t work for such signal, in such situation, a fixed scale is recommanded.
