Burn Charts

Am I completely lost or does Agile Accelerator not have release burn up charts?  If that is the case, any plans to add this functionality?  Or has anyone created their own that they can share details around?

Also, has anyone had an issue with the Sprint Burn Down charts?  When I access the sprint burn down from Work Manager, I get a nice, accurate graph.  However, when I use the Sprint Wall and open the charts, the graph is empty (or appears to plot all 0's).
