You can stack the plots, a build-in feature, each plot can have it's own scale.
Or if you have LabVIEW 2011, you can show/hide individual curve with the build-in check -box.
Or you can do show/hide with property node in earlier version of LabVIEW.
Zou, thanks very much for your quick response. I got the stack plot, what is property node or where can I find it? I have been using 2010 just since yesterday....
Many thanks in advance!
谢谢zou,您真是大好人
