Hmm, that certainly should not be happening, not sure quite why things
would be going like that. If you can, I would try slowing down the update
rate of the plot, to easily catch one of those instances and post some code
here if you can for us to try and replicate.
Another suggestion would be to set the invalid points to numpy.nan instead
of float("inf") and see if that gets better behavior; I think that was the
value we were originally looking for.
