Hello,

There is no reason not to be able to display gradient color for background.

Here is a screenshot of this and the xaml code:

<igCA:XamChart x:Name="XamChart1">

            <igCA:XamChart.Background>

                <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">

                    <GradientStop Color="GhostWhite" Offset="0"/>

                    <GradientStop Color="BlanchedAlmond" Offset="1"/>

                </LinearGradientBrush>

            </igCA:XamChart.Background>

            ...
