How can I switch channels on/off to be displayed in a waveform graph?

[keefa]

I have a VI which currently logs 15 analog channels to a data file and also displays these channels on a waveform graph. I would like to be able to switch channels on/off for the waveform graph during runtime but still continue to log them to the data file. Anyone know how I can do this?

hi keefa.
(first, please excuse me for my english, because I'm french 🙂 )
You can do what you want by displaying or not the curve on the graph.
I have made a light example with a 2D 8 chanels 5 points/chanel array.
After you have a "writing in a file" part.
You have both chanel display command on the front panel.
Test it, and ask me if some point are not very clear...

Hi Keefa

Here's another way which allows different numbers of channels.

nice one lanW.
An other good way to do it !

Thanks IanW and madness.
Both VIs worked a treat. I combined the best of both.
Many thanks
