Postprocessing Min=Max Voltage Range (albeit nonsensical) gets error

By accident I produced an error that would be quite expected. However, on the chance such an ill-formed input it has not been anticipated, I am reporting it so that, if desired, it might be caught before hand or handled otherwise.

After solving a problem (in case it matters, here is the fea):
human-elipsoid-in-tank-min-max.fea

if the postprocessing settings is set for Voltage with the specification of a range of equal min and max values:



then, when "Apply" is selected the plot does not include the voltage key,



a beep is heard, and an error window is displayed;



The full content of the error window:

v-equalRangeError.txt

As I said, I do not consider this a problem or bug necessarily, but thought you might like to know.

Kind regards,

Thank you for the report, all inputs aren't fully validated yet, and in this case as the error message indicates the Matlab caxis function only accepts a non-equal vector of length 2 hence triggering the error.
