C# Excel Library to Create ConicalColumn3D Chart

Aspose.Cells for .NET is a comprehensive Excel manipulation library that lets developers create, edit, and format Excel workbooks without Microsoft Office. It supports a wide range of chart types, including ConicalColumn3D, which is not available in the standard Office Interop APIs.

Key advantages of using Aspose.Cells for chart generation:

  • Rich API – Full control over chart type, series, axes, legends, and formatting.
  • Zero Dependencies – No need for Excel installed on the server.
  • High Performance – Efficient handling of large datasets.
  • Cross‑Platform – Works on Windows, Linux, and macOS with .NET Core/5/6+.

Get started in three simple steps:

  1. Install the library via NuGet:
    PM> Install-Package Aspose.Cells
  2. Create a Workbook instance and populate data.
  3. Add a ConicalColumn3D chart, configure series, and save the file.

Create a ConicalColumn3D Chart in Excel using C#

Below is a complete, ready‑to‑run C# console program that demonstrates how to build a ConicalColumn3D chart. The code follows best practices, includes detailed comments, and can be compiled with .NET 6 or later.

Explanation of the Code

StepWhat It Does
02Instantiates a new Workbook and grabs the first worksheet.
03Writes sample sales data for two quarters into cells A1:C3.
04Adds a ConicalColumn3D chart object positioned at rows 5‑25, columns 0‑10.
05‑06Creates two data series – one for Q1 and one for Q2 – and links them to the worksheet ranges.
07Demonstrates optional customizations: axis titles, series fill colors, legend positioning.
08Saves the workbook to an XLSX file that can be opened in Excel, Google Sheets, or any compatible viewer.

Running the Sample

  1. Create a new .NET console project (dotnet new console -n ConicalColumn3DChartDemo).
  2. Add the Aspose.Cells NuGet package (dotnet add package Aspose.Cells).
  3. Replace the generated Program.cs with the code above.
  4. Build and run (dotnet run).
    The file ConicalColumn3D_Chart_Output.xlsx will appear in the project’s output folder.
