HP QC 11.0 -> Dashboard -> Analysis View -> Progress Graphs are not working

Dear,

I am facing this issue in HP QC 11.0 -> Dashboard -> Analysis View -> Progress Graphs. When creating Progress Graphs and trying to view the results, it is throwing Warning Message:

Data could not be retrieved for some of the selected projects. The graph may display partial data.

Failed to get data from Project "Project_Name" in domain "Domain_Name" dure to an unexpected error. Contact your administrator for more details.

Please advice me on this.

Thanks,

Tanmay
