如何使用Apache poi 4.1.2在pie 3D图表中设置自定义颜色

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");

Drawing drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 5, 10, 15);
Chart chart = drawing.createChart(anchor);

ChartLegend legend = chart.getOrCreateLegend();
legend.setPosition(LegendPosition.BOTTOM);
ChartAxis bottomAxis = chart.getChartAxisFactory().createCategoryAxis(AxisPosition.BOTTOM);
ChartAxis leftAxis = chart.getChartAxisFactory().createValueAxis(AxisPosition.LEFT);
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);

ChartDataSource<Number> xs = DataSources.fromNumericCellRange(sheet, new CellRangeAddress(0, 4, 0, 0));
ChartDataSource<Number> ys = DataSources.fromNumericCellRange(sheet, new CellRangeAddress(0, 4, 1, 1));

ChartData data = chart.getChartDataFactory().createPieChartData(xs, ys);
data.setVaryColors(true);
chart.plot(data);

ChartSeries series = data.getSeries().get(0);
series.setFillColor(0, IndexedColors.RED.getIndex());
series.setFillColor(1, IndexedColors.GREEN.getIndex());
series.setFillColor(2, IndexedColors.BLUE.getIndex());

FileOutputStream fileOut = new FileOutputStream("output.xlsx");
workbook.write(fileOut);
fileOut.close();
workbook.close();
