Smarter automatic tick mark selection
Created by: btracey
I know tick mark selection is hard, but I think the current algorithm could be improved. If one generates 2-dimensional random numbers, and plots the result, the tick marks are at 0.3, 0.6, and 0.9. Given that the data is very close to being between 0 and 1, it seems more reasonable to me to have tick marks drawn at 0 and 1. If the minimum of the axis is changed to 0, then the ticks are at least 0, 0.3, 0.6 and 0.9
