class PieChartArea

extends ChartArea

A titled pie chart with legend exactly like PieChart2D with one difference. This chart does not keep the title near to it, when auto min sizing is disabled. In this scenario, the title would be near the top of the max size and the chart would be centered within the left over space. This is not desireable. PieChart2D forces the title as near as possible to the chart under unless explicitly set not to. PieChart2D uses this class. It creates one of these charts with min sizing enabled. That produces a chart that is where the title is forced near the chart, and the chart is centered in the middle of the area. But really, if any settings of the chart need to be changed they are generally changed here, or in one of its components available through a get method.

Returns the pie labels component of this chart in order to allow customization of it.

Returns:

The pie labels area.

resetPieChartAreaModel

void resetPieChartAreaModel(boolean reset)

Resets the model for this class. The model is used for shrinking and growing of its components based on the maximum size of this class. If this method is called, then the next time the maximum size is set, this classes model maximum size will be made equal to the new maximum size. Effectively what this does is ensure that whenever this objects maximum size is equal to the one given, then all of the components will take on their default model sizes. Note: This is only useful when auto model max sizing is disabled.

Parameters:

reset - True causes the max model to be reset upon next max sizing.

getPieChartAreaNeedsUpdate

boolean getPieChartAreaNeedsUpdate()

Indicates whether some property of this class has changed.

Returns:

True if some property has changed.

updatePieChartArea

void updatePieChartArea(java.awt.Graphics2D g2D)

Parameters:

g2D - The graphics context to use for calculations.

paintComponent

void paintComponent(java.awt.Graphics2D g2D)

Paints pie chart area components.

Overrides:

paintComponent in class ChartArea

Parameters:

g2D - The graphics context to use for calculations.
