I want show data labels with cell. what can I do

@ximoon,

I have observed your comments and shared sample code with you. This will help you to show data labels. If there is still an issue than please share your requirements in form of sample. We will investigate on our end to help you out.

using (Presentation pres = new Presentation())
{
IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Pie, 100, 100, 500, 400);
IChartSeries series = chart.ChartData.Series[0];
series.Labels.DefaultDataLabelFormat.ShowPercentage = true ;
series.Labels[0].DataLabelFormat.ShowValue = true;
series.DataPoints[2].Label.DataLabelFormat.ShowSeriesName = true;

            pres.Save("Presentation.pptx", SaveFormat.Pptx);
        }
