This is my code:
public static void main(String[] args) {
//ExStart:CreatingNormalCharts
// The path to the documents directory.
// String dataDir = Utils.getDataDir(CreatingNormalCharts.class);
// Instantiate Presentation class that represents PPTX file
Presentation pres = new Presentation();
// Access first slide
ISlide sld = pres.getSlides().get_Item(0);
// Add chart with default data
IChart chart = sld.getShapes().addChart(ChartType.ClusteredColumn, 0, 0, 500, 500);
// Setting chart Title
// chart.ChartTitle.TextFrameForOverriding.Text = “Sample Title”;
chart.getChartTitle().addTextFrameForOverriding(“Sample Title”);
chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(NullableBool.True);
chart.getChartTitle().setHeight(20);
chart.hasTitle();
// Set first series to Show Values
chart.getChartData().getSeries().get_Item(0).getLabels().getDefaultDataLabelFormat().setShowValue(true);
// Setting the index of chart data sheet
int defaultWorksheetIndex = 0;
// Getting the chart data WorkSheet
IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
// Delete default generated series and categories
chart.getChartData().getSeries().clear();
chart.getChartData().getCategories().clear();
int s = chart.getChartData().getSeries().size();
s = chart.getChartData().getCategories().size();
// Adding new series
chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 1, “Series 1”),chart.getType());
chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 2, “Series 2”),chart.getType());
// Adding new categories
chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 1, 0, “7.10”));
chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 2, 0, “7.10”));
chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 3, 0, “7.10”));
// Take first chart series
IChartSeries series = chart.getChartData().getSeries().get_Item(0);
// Now populating series data
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20));
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 50));
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 30));
// Setting fill color for series
series.getFormat().getFill().setFillType(FillType.Solid);
series.getFormat().getFill().getSolidFillColor().setColor(Color.RED);
// Take second chart series
series = chart.getChartData().getSeries().get_Item(1);
// Now populating series data
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 2, 30));
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 2, 10));
series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 2, 60));
// Setting fill color for series
series.getFormat().getFill().setFillType(FillType.Solid);
series.getFormat().getFill().getSolidFillColor().setColor(Color.GREEN);
// create custom labels for each of categories for new series
// first label will be show Category name
IDataLabel lbl = series.getDataPoints().get_Item(0).getLabel();
lbl.getDataLabelFormat().setShowCategoryName(true);
lbl = series.getDataPoints().get_Item(1).getLabel();
lbl.getDataLabelFormat().setShowSeriesName(true);
// Show value for third label
lbl = series.getDataPoints().get_Item(2).getLabel();
lbl.getDataLabelFormat().setShowValue(true);
lbl.getDataLabelFormat().setShowSeriesName(true);
lbl.getDataLabelFormat().setSeparator("/");
// Save presentation with chart
pres.save(“C:\Users\User\Desktop\” + “AsposeChart.pptx”, SaveFormat.Pptx);
//ExEnd:CreatingNormalCharts
