| PiePlot | | public class PiePlot extends Plot implements Cloneable,Serializable(Code) | | A plot that displays data in the form of a pie chart, using data from any
class that implements the
PieDataset interface.
Special notes:
- the default starting point is 12 o'clock and the pie sections proceed
in a clockwise direction, but these settings can be changed;
- negative values in the dataset are ignored;
- there are utility methods for creating a
PieDataset from a
org.jfree.data.category.CategoryDataset ;

visible - the flag.
See Also: PiePlot.getLabelLinksVisible() |
| setMaximumLabelWidth | | public void setMaximumLabelWidth(double width)(Code) | | Sets the maximum label width as a percentage of the plot width and sends
a
PlotChangeEvent to all registered listeners.
Parameters:
width - the width (a percentage, where 0.20 = 20 percent).
See Also: PiePlot.getMaximumLabelWidth() |
| setSectionOutlinesVisible | | public void setSectionOutlinesVisible(boolean visible)(Code) | | Sets the flag that controls whether or not the outline is drawn for
each pie section, and sends a
PlotChangeEvent to all registered
listeners.
Parameters:
visible - the flag.
See Also: PiePlot.getSectionOutlinesVisible() |
| setShadowXOffset | | public void setShadowXOffset(double offset)(Code) | | Sets the x-offset for the shadow effect and sends a
PlotChangeEvent to all registered listeners.
Parameters:
offset - the offset (in Java2D units).
See Also: PiePlot.getShadowXOffset() |
| setShadowYOffset | | public void setShadowYOffset(double offset)(Code) | | Sets the y-offset for the shadow effect and sends a
PlotChangeEvent to all registered listeners.
Parameters:
offset - the offset (in Java2D units).
See Also: PiePlot.getShadowYOffset() |
| setStartAngle | | public void setStartAngle(double angle)(Code) | | Sets the starting angle and sends a
PlotChangeEvent to all
registered listeners. The initial default value is 90 degrees, which
corresponds to 12 o'clock. A value of zero corresponds to 3 o'clock...
this is the encoding used by Java's Arc2D class.
Parameters:
angle - the angle (in degrees).
