I want to record some ECG tracings using the Ljstream with a labjack U3 but I would like to view two recordings at the same time in two differeny graphs. Please tell me how can I do that?
I would start with the example "U3 Stream Simple Example.vi". You can see that it passes a 2D array to the Waveform Graph. If you want 2 graphs instead, split this array as desired and pass the resulting 1D or 2D arrays to multiple graphs. I would look at the LabVIEW Help for graphs for some background info.
