How can I get the graphic of the a resistor-diode circuit's ID-VD graph?
Question
How to plot the I-V curve of a diode?

Answer
Setup


Results

I am testing a tunnel.  The current reading are too small to show clearly on only one continuous curve.  So I am plotting three separate curves:
(1) before negative resistance region,
(2) negative resistance region,
(3) after negative resistance region.
I also used the python matPlotLib plotting package to plot a single tunnel diode I-V curve, as shown below.
