Detailed Description

Class for the grid in a cartesian plane.

The CartesianGrid interface is used for calculating and for drawing the horizontal grid lines, and the vertical grid lines of a cartesian 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.

Reimplemented in KChart::LeveyJenningsGrid.
