Example 42 with RectangleInsets

use of org.jfree.chart.api.RectangleInsets in project ES-LEI-2Sem-2022-Grupo-1 by tmrbo-iscte.

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}. ie if value1 >
 * value2 then the section will be in green (unless
 * {@code greenForIncrease} is {@code false}, in which case it
 * would be {@code red}). 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} 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 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,

 *                          displayed in green (decrease red) if true.
 * @param legend  a flag specifying whether or not a legend is required.
