Hi Anton

My matplotlib version is 1.5.1. Can I solve this problem by updating the matplotlib package?

I came out another way to get around with this bug. I built a system that has same sites except it is 2-d. Then I plot the wavefunction calculated by 3-d on the 2-d system. It seems works, but I'm not sure whether this is a right way to do. Is this accurate?

Thanks

Sincerely,
Liming

Hi Liming,

I believe this is related to a known outstanding bug:

What version of matplotlib you are using?

Best,
Anton
