Hi Team,
Pie chart created using aspose slides is showing datalabels rounded off to whole value. Is it possible to show with decimal points as per original data? Below is my code.
Presentation presentation = new Presentation();
ISlide slides = pres.Slides[0];
// Add chart with default data
IChart chart = slides.Shapes.AddChart(ChartType.Pie, 247, 136, 375, 375);
chart.ChartTitle.AddTextFrameForOverriding("Sample Title");
chart.ChartTitle.TextFrameForOverriding.TextFrameFormat.CenterText = NullableBool.True;
chart.ChartTitle.Height = 20;
chart.HasTitle = true;
// Set first series to Show Values
chart.ChartData.Series[0].Labels.DefaultDataLabelFormat.ShowValue = true;
// Setting the index of chart data sheet
int defaultWorksheetIndex = 0;
// Getting the chart data worksheet
IChartDataWorkbook fact = chart.ChartData.ChartDataWorkbook;
// Delete default generated series and categories
chart.ChartData.Series.Clear();
chart.ChartData.Categories.Clear();
// Adding new categories
chart.ChartData.Categories.Add(fact.GetCell(0, 1, 0, "Category1"));
chart.ChartData.Categories.Add(fact.GetCell(0, 2, 0, "Category2"));
chart.ChartData.Categories.Add(fact.GetCell(0, 3, 0, "Category3"));
chart.ChartData.Categories.Add(fact.GetCell(0, 4, 0, "Category4"));
chart.ChartData.Categories.Add(fact.GetCell(0, 5, 0, "Category5"));
chart.ChartData.Categories.Add(fact.GetCell(0, 6, 0, "Category6"));
IChartSeries series = chart.ChartData.Series.Add(fact.GetCell(0, 0, 1), chart.Type);
// Now populating series data
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 1, 1, 71.44));
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 2, 1, 10.56));
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 3, 1, 5));
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 4, 1, 4.25));
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 5, 1, 1.75));
series.DataPoints.AddDataPointForPieSeries(fact.GetCell(defaultWorksheetIndex, 6, 1, 7));
series.Labels.DefaultDataLabelFormat.ShowLeaderLines = true;
series.Labels.DefaultDataLabelFormat.ShowPercentage = true;
series.Labels.DefaultDataLabelFormat.ShowCategoryName = true;
series.Labels.DefaultDataLabelFormat.TextFormat.PortionFormat.FontHeight = 11;
series.Labels.DefaultDataLabelFormat.Position = LegendDataLabelPosition.BestFit;
series.Labels.DefaultDataLabelFormat.Separator = ": ";
chart.HasLegend = false;
chart.HasTitle = false;
chart.Legend.TextFormat.PortionFormat.FontHeight = 11;
