Description

log(0) is not a real number, so we can't actually plot it on the axis.

It's not as simple as removing this line in WAxis::mapToDevice, though:

u = std::max(s.renderMinimum, u);

This is because other functionality does not deal correctly with non-finite results of mapToDevice, and some functions explicitly call it with value 0.
