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.
