Create a Pie3DExploded Chart in Excel using C#

Below are two complete, runnable examples:

  1. Basic Pie3DExploded chart – Shows how to create the chart and explode the whole series.
  2. Customized Pie3DExploded chart – Demonstrates styling, exploding specific slices, and exporting to PNG.

Example 1 – Basic Pie3DExploded Chart

Explanation of key steps

StepCodePurpose
1new Workbook()Creates an in‑memory Excel workbook.
2sheet.Cells["A1"].Value = "Category"Fills the worksheet with category/value pairs.
3sheet.Charts.Add(ChartType.Pie3D, …)Adds a 3‑D pie chart to the sheet.
4chart.NSeries.Add("=Sheet1!$B$2:$B$5", true)Binds the series to the data range.
5chart.NSeries[seriesIndex].Explosion = 15Increases the distance between slices for a more pronounced effect.
6workbook.Save(...)Writes the workbook to an XLSX file.

Running the program produces Pie3DExploded_Basic.xlsx with a clean 3‑D exploded pie chart.

Example 2 – Customized Pie3DExploded Chart (Styling & Export)

What this example adds

  • Selective explosion – Only the “Bikes” slice is separated using ExplodePoints.
  • Custom slice colors – Directly accesses each point’s Area.ForegroundColor.
  • Data labels – Shows category name and value inside each slice.
  • High‑resolution export – Saves the chart as a 300 dpi PNG image (ToImage method).

Both examples compile with .NET 6+ and require only the Aspose.Cells NuGet package.
