I am sending successive waveforms - as my measurement progresses - to the same plot window, where I display them together using the "next curve" pin.
Since at the end I will have A LOT of them (even 100 or more) I wanted to have each new one in a slightly different color, to see at a glance some changes...

Unfortunately I cannot find out how to do it! Any help?

I don't think you can control the color of an individual trace line during the execution of the code. Maybe there is another way of doing this, but as far as I know, there is not possible with native VEE.

Try this program. You need to add a "Traces" control pin to your X vs. Y plot first, then a record scalar containing TraceNum and Pen is fed to that pin.

  ouch! I went immediately to your file, but I fear I have a too old version of VEE (v.7.03)...
  After some warnings of interfaces in instrument config file not enabled (for GPIB-VISA, ASRL), I got a warning for +ignoring unknown keyword "eoiEnabled"+, and finally an error for +Mismatch error: expected property, got EnableColorCoding, error n.640+.
  
  I fear my version is just too old but - just in case - could you describe the procedure so that I can try to replicate it, since I know that the "traces" control pin is available ?

    Hi,
    I've cleared the program's instrument list as this isn't required here. I've also taken a screenshot of the program's detail view. Hopefully this will work for you.

    Right click on your chart and and a Control Input called Traces. That will allow you to select Pen color (See VEE help).
