Selecting plot in a Wave Chart

[George7893]

Hi everyone,

I'm new in LabView, and I'm trying to plot several signals adquire by an adquisition device in a Wave Chart. I want to have different checkboxes in order to be able to select which signals are supposed to be represented. I made lots of test but it doesn't work in any of them. Now I have a structure event which uploads the Visible property of the chart with the value of the cluster of checkboxes (saw in a NI forum). In the while loop, the chart is continuously updating, but It doesn't plot the signals indicated by the cluster.

Thank in advance!

I give a capture of the actual design.

Why do you attach an image of your code? We cannot edit/debug/run images with LabVIEW!

Next time attach your VI...

Why don't you use the plot legend of your WaveformChart? Just display (and use) the plot visibility checkboxes!

Note:

I think, it is not easy to find this feature. That's why a picture. Right-click on a plot description, not into the legend picture:

The problem is that if I use the checkboxes from the legend then I couldn't use the signals of that checkboxes for anything else. So my idea was to make external checkboxes.

I attach you the VI

Well, you could read the plot visibility property.

This will give you the value of those plot legend checkboxes!
