Create a SurfaceContour Chart in Excel using C#
Below is a complete, ready‑to‑run C# console application that creates a workbook, populates it with dummy three‑dimensional data, adds a SurfaceContour chart, customizes its appearance, and saves the result as an Excel file.
Explanation of the Code
| Step | What It Does |
|---|---|
| 1 | Creates a new Workbook and accesses the default worksheet. |
| 2 | Populates a 5 × 5 data grid together with X‑ and Y‑axis labels. |
| 3 | Inserts a SurfaceContour chart at the desired location on the sheet. |
| 4 | Defines the whole range (A1:F6) that contains the data and headers. |
| 5 | Assigns X‑axis (category) and Y‑axis (series) labels so the chart knows how to map values. |
| 6 | Optional formatting – gradient fill, legend positioning, and chart border styling. |
| 7 | Saves the workbook as an XLSX file that can be opened in Excel. |
Run the program, open SurfaceContourChart_Output.xlsx, and you will see a smooth color‑filled contour surface that visualizes the underlying data.
