I'm not familiar with the PrimeFaces charting components, but from the stack trace, it looks like you haven't set any categories for it to plot. Categories are what appear (usually) on the horizontal axis of a bar or line chart. It sounds like the chart just doesn't have any data to work with.
 
I'm still in control here. LOOK at this tiny ad!
