Trouble with Theming of Line and Area Charts

[Steven]

I am having problems with theming of line and area charts.  When I apply a custom theme and have a LineSeriesDefinition or some of the other line and area series definitions, I get an exception.  Leaving everything else the same, if I define the chart with a BarSeriesDefinition instead, it will work fine.  The error isn't helpful enough for me to debug the problem effectively.  The error is as follows:

I realize it's a long shot, but can someone shed some light on this problem?

Hi Steven,

Here is my answer copied from the other thread concerning the same issue:

When you have a custom theme applied to RadChart, there is one step in addition which needs to be done with the chart xaml. More information can be found in our help, and this help topic in particular. You need to add storyboards for your custom theme in the Chart.xaml file. Attached is its modified version.

Greetings,

Thank you for your prompt response.  This was exactly my problem.  I suppose I should RTFM...
