public void setMinimumArcAngleToDraw(double angle)

Sets the minimum arc angle that will be drawn. Pie sections for an angle smaller than this are not drawn, to avoid a JDK bug. See this link for details:

public void zoom(double percent)

A zoom method that does nothing.

Plots are required to support the zoom operation. In the case of a pie chart, it doesn't make sense to zoom in or out, so the method is empty.

Overrides:

zoom in interface Plot

Parameters:

percent - the zoom percentage.
