Detailed Description

Plot layer implementing a y-scale ruler.

If align is set to mpALIGN_CENTER, the ruler is fixed at X=0 in the coordinate system. If the align is set to mpALIGN_TOP or mpALIGN_BOTTOM, the axis is always drawn respectively at top or bottom of the window. A label is plotted at the top-right hand of the ruler. The scale numbering automatically adjusts to view and zoom factor.
