RadCartesianChart background color defaults to White on iOS rather than Transparent

Hi Steve,

Yes, this is correct and is expected behavior due to the native platform differences as the Chart control is not a pure MAUI-only element. Instead they are three separate native chart controls, raised up to .NET MAUI through compatibility handlers.

So, in the case of iOS, the default background is indeed white, thus if you want it to be transparent, you can override it bey setting the BackgroundColor="Transparent":

<telerik:RadCartesianChart x:Name="MyChart" BackgroundColor="Transparent">
   ...
</telerik:RadCartesianChart>
