Create Excel Chart in C# and VB.NET
The following example shows how you can create an Excel chart in C# and VB.NET and select data for it using the GemBox.Spreadsheet component.
Excel charts are supported in XLSX, HTML, PDF, XPS, and image formats. In HTML, charts are converted to images.
To convert an existing workbook with charts into another file format, use Convert example.
For more information about charts, see the Charts help page.

Excel combo chart
An Excel combo (combination) chart is a special chart type that combines two or more chart types in a single chart.
The following example shows how you can create an Excel combo chart in C# and VB.NET and select data for it using the GemBox.Spreadsheet component.
As all other chart types, combo chart is also supported in XLSX, PDF, XPS, and image formats.
