Example 36 with PiePlot

use of org.jfree.chart.plot.PiePlot in project SIMVA-SoS by SESoS.

the class PieChartTest method testReplaceDatasetOnPieChart.

/**
 * Using a regular pie chart, we replace the dataset with null.  Expect to
 * receive notification of a chart change event, and (of course) the
 * dataset should be null.
 */

Example 37 with PiePlot

use of org.jfree.chart.plot.PiePlot 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.
