Create a Chart in PPTX - Java

Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);
    IChart chart = slide.getShapes().addChart(ChartType.ClusteredColumn, 0, 0, 500, 500);

    chart.getChartTitle().addTextFrameForOverriding("Sales by quarter");
    chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(NullableBool.True);
    chart.getChartTitle().setHeight(20);
    chart.setTitle(true);

    chart.getChartData().getSeries().get_Item(0).getLabels().getDefaultDataLabelFormat().setShowValue(true);

    int defaultWorksheetIndex = 0;
    IChartDataWorkbook chartDataWorkbook = chart.getChartData().getChartDataWorkbook();

    chart.getChartData().getSeries().clear();
    chart.getChartData().getCategories().clear();

    chart.getChartData().getSeries().add(chartDataWorkbook.getCell(defaultWorksheetIndex, 0, 1, "Series 1"), chart.getType());
    chart.getChartData().getSeries().add(chartDataWorkbook.getCell(defaultWorksheetIndex, 0, 2, "Series 2"), chart.getType());

    chart.getChartData().getCategories().add(chartDataWorkbook.getCell(defaultWorksheetIndex, 1, 0, "Category 1"));
    chart.getChartData().getCategories().add(chartDataWorkbook.getCell(defaultWorksheetIndex, 2, 0, "Category 2"));
    chart.getChartData().getCategories().add(chartDataWorkbook.getCell(defaultWorksheetIndex, 3, 0, "Category 3"));

    IChartSeries firstSeries = chart.getChartData().getSeries().get_Item(0);
    firstSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 1, 1, 20));
    firstSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 2, 1, 50));
    firstSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 3, 1, 30));
    firstSeries.getFormat().getFill().setFillType(FillType.Solid);
    firstSeries.getFormat().getFill().getSolidFillColor().setColor(java.awt.Color.RED);

    IChartSeries secondSeries = chart.getChartData().getSeries().get_Item(1);
    secondSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 1, 2, 30));
    secondSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 2, 2, 10));
    secondSeries.getDataPoints().addDataPointForBarSeries(chartDataWorkbook.getCell(defaultWorksheetIndex, 3, 2, 60));
    secondSeries.getFormat().getFill().setFillType(FillType.Solid);
    secondSeries.getFormat().getFill().getSolidFillColor().setColor(java.awt.Color.GREEN);

    IDataLabel firstDataLabel = secondSeries.getDataPoints().get_Item(0).getLabel();
    firstDataLabel.getDataLabelFormat().setShowCategoryName(true);

    IDataLabel secondDataLabel = secondSeries.getDataPoints().get_Item(1).getLabel();
    secondDataLabel.getDataLabelFormat().setShowSeriesName(true);

    IDataLabel thirdDataLabel = secondSeries.getDataPoints().get_Item(2).getLabel();
    thirdDataLabel.getDataLabelFormat().setShowValue(true);
    thirdDataLabel.getDataLabelFormat().setShowSeriesName(true);
    thirdDataLabel.getDataLabelFormat().setSeparator("/");

    presentation.save("chart-presentation.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}
