Usage

From source file:ca.sqlpower.wabit.swingui.chart.ChartSwingUtil.java

/**
 * Creates a chart that displays multiple 3D pie plots that have a GradientPaintTransformer.  
 * The chart object returned by this method uses a {@link MultiplePiePlot} instance as the plot.
 *
 * @param title  the chart title (<code>null</code> permitted).
 * @param dataset  the dataset (<code>null</code> permitted).
 * @param order  the order that the data is extracted (by row or by column)
 *               (<code>null</code> not permitted).
 * @param legend  include a legend?/*from   w  w w .j a va2s .co  m*/
 * @param tooltips  generate tooltips?
 * @param urls  generate URLs?
 *
 * @return A chart.
