| Type | Description |
|---|---|
| DataPointCollection | A DataPointCollection object that is the collection of customized data points. |
Remarks
To change the visual appearance for a specific data point in a series, add an item to the DataPointCollection collection with the index equal to an index of the selected data point and use the DataPoint properties to specify its appearance.
For a chart of the ChartType.Pie3D type, you can use the DataPoint.Explosion property to set the point explosion, as illustrated in the following code sample.
The example below demonstrates how to create the 3-D pie chart and rotate it around the Y-axis by 225° using the View3DOptions.YRotation property.
Worksheet worksheet = workbook.Worksheets["chartTask3"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Create a chart and specify its location
Chart chart = worksheet.Charts.Add(ChartType.Pie3D);
chart.TopLeftCell = worksheet.Cells["H2"];
chart.BottomRightCell = worksheet.Cells["N14"];
// Add the data series
chart.Series.Add(worksheet["E2"], worksheet["B3:B6"], worksheet["E3:E6"]);
// Set the explosion value for the slice
chart.Series[0].CustomDataPoints.Add(2).Explosion = 25;
// Set the rotation of the 3-D chart view
chart.View3D.YRotation = 255;
// Set the chart style
chart.Style = ChartStyle.ColorGradient;
