drawGrid()

void CartesianGrid::drawGrid ( PaintContext *  context )

overridevirtual

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 KDChart::AbstractGrid.

Reimplemented in KDChart::LeveyJenningsGrid.
