Hi,
You will probably have to implement a function to find a sqrt (if it
exists) in terms of other higher level primitives.
See https://en.wikipedia.org/wiki/Square_root_of_a_matrix and

Hi,
I think I randomly ran into this same thing with sage-9.8 this week too.
My guess is that there is some sort of overflow bug in the computation of
the y-axis labels. It's probably one of the most severe bugs in sage ever,
since it is so likely to be randomly misleading...

Thanks Vincent!What version of Sage are you using? With sage-9.8 I get:
