C# Class Smrf.WpfGraphicsLib.Axis

Draws a linear axis with major and minor gridlines, major gridline values, and an axis label.

This can be used as either a horizontal x-axis (the default) or a vertical y-axis. For the latter, set IsXAxis to false.

The axis is meant to be docked below or to the left of the control to which the axis applies. If you set the to the render transform of the docked control, the axis will adjust itself as the docked control is zoomed or translated.

Call SetRange to set the range of values in the axis.
