Member Function Documentation

◆ drawGrid()

void RadarGrid::drawGrid ( PaintContext * context)

Doing the actual drawing.

Every derived class must implement this.

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.
