An adaptor class that converts any CategoryDataset into a PieDataset , by taking the values from a single row or column.

Usage

From source file:org.openfaces.component.chart.impl.plots.MultiplePiePlotAdapter.java

public MultiplePiePlotAdapter(CategoryDataset ds, TableOrder order, Chart chart, PieChartView view) {
    super(ds);/*from   w w w.jav a 2  s  . co m*/

    TextTitle seriesTitle = getSeriesTitle(chart);
    getPieChart().setTitle(seriesTitle);

    PiePlot piePlot = (PiePlot) getPieChart().getPlot();
    piePlot.setDataset(new CategoryToPieDataset(ds, order, 0));
