Surface charts are useful when you want to find the optimum combinations between two data sets. As in a topographic map, the colors and patterns indicate the areas that are in the same range of values. A surface chart plots data on a three-dimensional surface, in a similar way that topographic maps plots elevation. The colors and patterns represent values within the same range. This chart type is especially useful for finding the optimum results when comparing two or more sets of data.
DsExcel supports the following types of Surface charts.
Chart Type | Chart Snapshot | Purpose |

Refer to the following code to add SurfaceWireframe chart.
public void SurfaceCharts()
{
// Initialize workbook
Workbook workbook = new Workbook();
// Fetch default worksheet
IWorksheet worksheet = workbook.Worksheets[0];
// Prepare data for chart
worksheet.Range["A1:D4"].Value = new object[,]
{
{null, "Q1", "Q2", "Q3"},
{"Mobile Phones", 1330, 2345, 3493},
{"Laptops", 2032, 3632, 2197},
{"Tablets", 6233, 3270, 2030}
};
worksheet.Range["A:D"].Columns.AutoFit();
// Add Surface Chart
IShape surfaceChartShape = worksheet.Shapes.AddChart(ChartType.SurfaceWireframe, 250, 20, 360, 230);
// Adding series to SeriesCollection
surfaceChartShape.Chart.SeriesCollection.Add(worksheet.Range["A1:D4"], RowCol.Columns, true, true);
// Configure Chart Title
surfaceChartShape.Chart.ChartTitle.TextFrame.TextRange.Paragraphs.Add("Annual Sales Record");
// Saving workbook to Xlsx
workbook.Save(@"25-SurfaceChart.xlsx", SaveFileFormat.Xlsx);
