Hello,

I'm using the evaluation version of the charting tool for SSRS.  When trying to preview a simple chart I'm receiving the following error message:

                                         NChart Rendering Failed.  Exception was: The object is not compatible with the data series type.

This is a line chart with times along the vertical axis, categorized by a process ID and labeled with a process name on the horizontal axis.  The time data is pulled from a stored procedure as Time(0) having the format of hh:mm:ss .  The vertical axis has the Sub Type set to DateTime (don't know if that's relavent).   

This works with a standard SSRS chart, but I'm not understanding where the object incompatibility exists.  Below is a screen shot of chart in development.  Interestingly, when I remove the "=" from the Start Time expression, the chart displays without data, and without error.

I'm relatively new to charting in general.  Any ideas or suggestions are most appreciated.

Thanks,

Joe
