Waveform Graph Auto Property

[jspaarg]

Is there a way to select between auto scale and fixed scale from a waveform graph property node?

It is easy to find from the front panel properties, but I cannot seem to find it on the property node.

The goal is to allow the user to select a specific segment of a displayed waveform and enter min and max values for the scale.

Perhaps there is a better way to do this.

Cursors?

Also, can I display two different plots (with the same timebase) simultaneously.

Any help is appreciated.

Hi:

I've found a way to select the Autoscale property of a Waveform Graph. Please see the screenshot that is attached with this message. If you want to show more than one plot in the Waveform graph you need to input one of the multiplot datatypes that the Waveform Graph accepts. For your application one suitable may be a Cluster that contains an X0 Value, a Delta X value and a two dimensional array of Y data. Each row in the array represents a plot. Try to search in the Examples included in LabVIEW, look for an example called "Waveform Graph.vi" that is contained in an the gengrap.llb library. In my PC it's located at "C:\Program Files\National Instruments\LabVIEW 7.0\examples\general\graphs"

Hope this helps.

I saw that property, but it comes up as an integer as opposed to a boolean.

I just assumed that since auto is a checkbox on the control's front panel property that it would be a boolean in the block diagram property.

I will give it a try.

Thanks for the info on the multiple inputs.

I need to read up and try some cursors as well.
