I have the following code to generate a pie chart.
Everything works fine but i’m not able to get leader lines although it’s value has been set to true.
Presentation presentation = new Presentation();
// Access first slide
ISlide slides = presentation.getSlides().get_Item(0);
// Add chart with default data
IChart chart = slides.getShapes().addChart(ChartType.Pie, 100, 100, 400, 400);
// Setting chart 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();
// Adding new categories
chart.getChartData().getCategories().add(fact.getCell(0, 1, 0, "First Qtr"));
chart.getChartData().getCategories().add(fact.getCell(0, 2, 0, "2nd Qtr"));
chart.getChartData().getCategories().add(fact.getCell(0, 3, 0, "3rd Qtr"));
// Adding new series
IChartSeries series = chart.getChartData().getSeries().add(fact.getCell(0, 0, 1, "Series 1"), chart.getType());
// Now populating series data
series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20));
series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 50));
series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 30));
series.getLabels().getDefaultDataLabelFormat().setShowValue(true);
series.getLabels().getDefaultDataLabelFormat().setShowCategoryName(true);
series.getLabels().getDefaultDataLabelFormat().setPosition(LegendDataLabelPosition.OutsideEnd);
series.getLabels().getDefaultDataLabelFormat().setShowLeaderLines(true);
series.getParentSeriesGroup().setColorVaried(true);
chart.setLegend(false);
presentation.save(dataDir + "Sample2.pptx", com.aspose.slides.SaveFormat.Pptx);
