Uneven tick spacing #14
Description
Because of rounding, the tick spacing can be uneven. Let's say you try to fit a range of 0, 10, 20, 30, 40, 50 in a height of 8 characters, some ticks will have a spacing of two characters, and some will have a spacing of a single character. See here:
I can implement a method which you can call to adjust the axis to include a bit more space so that the tick spacing is a bit reduced in some places but even over the whole range. The tick spacing should be reduce to an integer number. BUT: what to do when zooming? In that case the tick spacing will quickly become uneven again. Should we then set a flag and call the 'rounding down' method for every zoom action?
