Link the "plot legend" checkboxes to individual booleans

Solved!
Go to solution

Hi all,

 

I'm saving DAQ data from a waveform graph (where different channels are displayed as differently-colored plots on the same chart) and I want "unchecked" plots in the legend to go unsaved.

 

Ideally there would be some kind of boolean value associated with each checkbox which I could then use to say "yes, record" or "no, don't record."

 

Is there any way to do this? Or is there a better solution than this?

I presume you are referring to the "Plot Visibility Checkboxes." You can use two property nodes for the graph: Active Plot and Plot Visible. Together those should get you the information you want.

I don't think those property nodes give the results I want -- those refer to the visibility of the checkboxes as a group. What I'm looking for is the boolean value associated with each checkbox.

It works for me. I am using LV 2014. I happened to have a VI with a graph with the checkboxes used so I added the property nodes as a test. The values in the boolean array follow the visibility checkboxes checked exactly.

 

Note: The array of clusters wired to the autoindexing tunnel is the data going to the graph. This tells the for loop how many plots exist.

Thanks, Lynn. I came back to tell you that I was mistaking and that I got it working, but your additional answer clarified things still futher.
