Detailed Description

Handles an axis on a plot.

Manages the positions in a 2D plot. The axis can be logarithmic. getRelPos returns the relative position on the axis. If the point is between the start and stop of the range, this will be between 0 and 1.

The axis will determine a good position wrt the border. To determine where the axis starts and stops, you can provide other axis handlers. If you don't provide these, the border_ will be used. The border_ on the side of the axis will always be used. If you do use begin and end handlers, you'll have to call setRange() for all before using plotAxis().

The drawAxis will plot the axis. If LineStyle::Type is not LineStyle::None, grid lines will be drawn, too. If it is None, then still the color and size will be used for drawing the axis (the axis' style is always Solid).

Use AxisLayout (linear.h) to find 'nice' ranges, like: AxisLayout al( Interval<float>(start,stop) ); ahndlr.setRange( StepInterval<float>(al.sd.start,al.stop,al.sd.step) );
