Detailed Description
Class for the grid in a polar plane.
The PolarGrid interface is used for calculating and for drawing the sagittal grid lines, and the circular grid lines of a polar coordinate plane.

Doing the actual drawing.
Every derived class must implement this.
- Note
- When implementing drawGrid(): Before you start drawing, make sure to call updateData(), to get the data boundaries recalculated. For an example, see the implementation of CartesianGrid:drawGrid().
Implements KChart::AbstractGrid.
