Example 36 with StandardPieSectionLabelGenerator

use of org.jfree.chart.labels.StandardPieSectionLabelGenerator in project SIMVA-SoS by SESoS.

the class ChartFactory method createPieChart.

/**
 * Creates a pie chart with default settings that compares 2 datasets.
 * The colour of each section will be determined by the move from the value
 * for the same key in <code>previousDataset</code>. ie if value1 &gt;
 * value2 then the section will be in green (unless
 * <code>greenForIncrease</code> is <code>false</code>, in which case it
 * would be <code>red</code>). Each section can have a shade of red or
 * green as the difference can be tailored between 0% (black) and
 * percentDiffForMaxScale% (bright red/green).
 * <p>
 * For instance if <code>percentDiffForMaxScale</code> is 10 (10%), a
 * difference of 5% will have a half shade of red/green, a difference of
 * 10% or more will have a maximum shade/brightness of red/green.
 * <P>
 * The chart object returned by this method uses a {@link PiePlot} instance
 * as the plot.

 *
 * @param title  the chart title (<code>null</code> permitted).
 * @param dataset  the dataset for the chart (<code>null</code> permitted).
 * @param previousDataset  the dataset for the last run, this will be used
 *                         to compare each key in the dataset
 * @param percentDiffForMaxScale scale goes from bright red/green to black,
 *                               percentDiffForMaxScale indicate the change
 *                               required to reach top scale.
 * @param greenForIncrease  an increase since previousDataset will be
 *                          displayed in green (decrease red) if true.
 * @param legend  a flag specifying whether or not a legend is required.
 * @param tooltips  configure chart to generate tool tips?
 * @param urls  configure chart to generate URLs?
 * @param subTitle displays a subtitle with colour scheme if true
 * @param showDifference  create a new dataset that will show the %
 *                        difference between the two datasets.
 *
 * @return A pie chart.
