Detailed Description

Class for the grid in a Levey Jennings plane.

The LeveyJenningsGrid interface is used for calculating and for drawing the horizonal grid lines, and the vertical grid lines of a Levey Jennings coordinate plane.

Member Function Documentation

void LeveyJenningsGrid::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().

Reimplemented from KChart::CartesianGrid.
