Hello Michael Stuart,
Thanks for the kind words! And the feedback. The background property is not working because we hardwired the white background into the template, something we didn't have the time to properly style for the release. We are working on removing such issues. As a WPF component, the chart can of course be fully customized by overriding its templates even right now, however, we are with you that it should allow for a much easier customization. We will be specifically targeting ease of use and customizibility this upcoming Q so you will see some big improvements there.
We wholeheartedly agree with you that although RadChart for WPF is the richest wpf chart on the market there is still a lot to be desired from this product. It's still a v1.0 and it will take great feedback like yours to make this a great product like the rest of the telerik rad controls.
Your telerik points have been updated.
All the best,
the Telerik team
