    chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(NullableBool.True);
    chart.getChartTitle().setHeight(20);

    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().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));
