Programmable Y-Axes in Waveform Chart

[MogaRaghu]

In an application, there is a need for me to display multiple trends of  parameters ( as selected by the user ) in the same waveform chart. Just see the enclosed sample VI.

In that for each of the 3 Channels in the Y-Axis, I want to programatically change the,

A. Span of the Y-Axis scale
B. The tick mark intervals

Have been exploring the property nodes but have not been able to make any progress. Maybe I am missing something. Can someone tell me if its possible at all to do what I want to do ?

( I am using  LV7.1 + Win_XP)

Thanks

Hi

Basically what you want to do is possible, using the property-node (see the example). The problem is that you have to create the y-scales manually, which is a little bit uncomfortable if you have a dynamic number of scales.

Anyway - you can create a new y-scale by right-clicking the first scale and select "duplicate scale".

In the example I create two additional scales, which can be toggled visible.

Hope this helps.

Hello,

Thanks for the guideline. I have enclosed the VI after a small addition to include the Span value.

I guess that this is the only way to change the scale parameters - one at a time by selecting that scale as the active one.

Maybe some more work will be needed to make it more user friendly.
