Multiple Plots with USB-4761 Relay and Keithley 2450

[m943]

Hi,

I have written a vi (attached) that sweeps voltage from a Keithley 2450 in conjuction with an Advantech USB-4761 relay to automate the measurement of various devices in order. I want the current/voltage measurements from all device to be graphed on one plot in distinguishing colors but have not been able to find a way to do so. They are all being graphed as the same color. I tried adding and displaying multiple plots to my XY-graph (Plot 1 is red, Plot 2 is green, etc.) but all my graphs still registered as Plot 0 despite this change, and I was not able to distinguish one device's measurements from another. I also experimented with the Mixed Signal Graph option and had similar issues. Does anyone have any suggestions?

Thank you!

Does anyone have any ideas?

Here is a forum post that goes through a very similar situation.  The hardware is likely different, but since the issue is in the graph that should not matter.

Also, here is a paper and an example that can be helpful.
