Category Data Labels on Pie Chart

[Brian]

I''m trying to create a pie chart with labels for each section of the pie along with the associated value. And I would pefer that it not be in a lengend. With my code shown below I am not able to get it to show the category labels. My data has a label in column B and the value (percentage) in column C. Is there something that I am doing wrong? Any suggestions would be great. Thanks, Brian

IChartShape chart = _CurrentWorksheet.Charts.Add();
chart.ChartType = ExcelChartType.Pie_3D;

chart.Series.Add();
chart.Series[0].CategoryLabels = _CurrentWorksheet.Range["B22:B27"];
chart.Series[0].Values = _CurrentWorksheet.Range["C22:C27"];

chart.IsLegendVisible = false;
chart.LabelsSeparator = " ";
chart.IsLabelsCategory = true;
chart.IsLabelsValue = true;

Hi Brian, Sorry for the delay in responding to you. Please use the following code for displaying values and labels in series.

IChartDataPoint point = chart.Series[0].DataPoints.DefaultDataPoint;
IChartDataLabels labels = point.DataLabels;
//Setting labels in series.
labels.IsCategoryName=true;
//Setting value in series.
labels.IsValue = true;

Here is the sample for your reference:Chart_labels.zip Regarding setting labels in series, currently there are some issues in it. I will consult with the development team regarding this and send you an update as soon as possible. Please let me know if you have any other concerns. Thanks, Bharath.
