If a bin size of 0 made it through, this could lead to infinite loops or divide-by-zero errors somewhere else. It looks like Axes.autoTicks has its own fallback for this so dummyAx.dtick won't be zero, which is why this works for now, but perhaps it would be better to use size0 = 1 instead so we don't have to depend on this behavior from autoTicks?
- for better protection from infinity loops in Axes.autoTicks

This case and the two below resulted in errors previously.
