I suppose this is about the native DateTime values support. For the moment RadChart supports the OLE Automation date equivalent (which is double). This equivalent is easily retrieved using the DateTime.ToOADate() method. Adding native support for DateTime values would require significant changes in the control, while it would not actually add a feature which is completely missing at the moment. That said, native DateTime support is not in our plans for Q1 2009. Nevertheless, we will forward your feedback to our developers for future consideration.
We extend our apologies for not being able to meet all your needs and we hope that the OLE Automation date equivalent support in RadChart will suffice. Of course, we are ready to provide assistance whenever you may need it.
