Plots as implemented are dual sweep. Please add the ability to only plot in one direction.

Thank you for this impressive application. I have the latest released version running under Python 3.7.2. My instrument is a 2602B. I have used the family of curves feature and the Vgs-Id feature.

Issue 1
The tests as implemented traverse "start voltage to end voltage and then back to start voltage". This is called a dual sweep and is used sometimes to show hysteresis where it exists. where hysteresis does not exist, the reverse direction only shows that the part is heating up and shows how much temperature coefficient exists.

It would be helpful to be able to only plot from start voltage to end voltage and then stop.

Issue 2

It would be helpful to be able to turn off plotting of gate current. Gate current is largely irrelevant for these plots.
It would be helpful to remove the "source current " plot. This data is largely irrelevant for most applications. If someone wants to know this information, they could add the drain current to the gate current.

A family of curves plot should only show drain current vs drain voltage and only from lower voltage to higher voltage and not in the reverse direction.

Once again, thanks for this application. Impressive work.

I would tear into this myself if I was a programmer but I know very little about Python. Just enough to build very simple applications.

I would be happy to discuss via email or a voice call.
