Lock Y axis for zooming

[David Moerman]

OK, granted I've been a little thick in the past.  But I've hunted enough and still haven't found a way to do this, so maybe this is a LabVIEW product improvement request.

I have a waveform graph with multiple Y axes and multiple plots.  In fact, 4 plots with each plot assigned to a different Y scale.  I would like to use the zoom and pan tools on ONLY ONE of the plots at a time, while the others stay in a fixed position (of course, I realize they would all have to change together in the X direction).  The current LabVIEW behaviour forces all the scales to change at the same time, but I would like to selectively lock individual Y scales.

Well I *could* build a bit of code that tracks the min/max of each Y axis, but is there some obscure property setting that allows me to do this?  If not, I think a button on the scale legend should be provided for this.

Thanks,
-Dave

Hi Dave,

I can see how convenient it would be to be able to zoom on only one Y-scale at a time, or maybe have the option to lock some of the Y-scales when zooming. However, this feature is not built into the current Waveform Graph, so the solution is (as you mention) to perform this functionality in code by using Property Nodes.

I like your idea, so don't forget to submit it as a product suggestion by using the "feedback" link on www.ni.com/contact.

Thanks!
