I'm still working through using the RadChart in my application and when I bring in DateTime values on the X axis I find that the values haven't got any bearing on reality. The DateTime values that are displayed should be at 1 hour intervals and with only 5 samples I can see that the DateTime value displayed is incremented by 1 day instead of 1 hour. I have carefully inspected the values that I am inserting and they vary by 1 hour, however they are displayed incorrectly in the chart. After reviewing the Forum, I found this thread and I found a post that sounded similar, but I needed to clarify it. Is this http://www.telerik.com/community/forums/silverlight/chart/radchart-tooltip-axisx.aspx
post describing a similar problem? The RadChart really can't display the correct DateTime based on a OLE formatted value?
