I'm confused why adding the ymin and ymax optional arguments fixes the problem. They seem like independent behaviors. Also, I spoke too soon about it working on Sympy. I simply tried the Live Sympy cell online with the default arguments, where it does work. However, if you use sympy on the command line, it seems to have the same sort of bug. Your suggestion below suggests it is an upstream bug in matplotlib, right? Notice the label 1e-6 + 1, the offset option for matplotlib.
