+# How to set the background color for Excel Chart in C#?
+
+You can set the background color of a chart by customizing either the plot area or the chart area. XlsIO allows you to set the background color for both the PlotArea and ChartArea using the [ForeColor](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IFill.html#Syncfusion_XlsIO_IFill_ForeColor) property of the [IFill](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IFill.html) interface.
+
+
+The following code example illustrates how to set the background color for Excel Chart in C# (cross-platform and Windows-specific) and VB.NET.
