The ticks were recalculated twice per plotDive() call:
1) When updating the position of the axes in updateChangeLine()
2) After setting the bounds in plotDive() via setBounds()
Remove the first instance. updateChangeLine() is called in
only one place [from plotDive()] and therefore, the recalculation
is always redundant. Moreover, rename the function to setPosition(),
since it doesn't do any animation at all.
