My boss found there was no way to view a history burn data chart on tfs 2013 through web access, only current data can be seen like the picture shown. So he wonders how to export history burn down chart, maybe last month chart or something.
I searched ways to export burn down chart, and found maybe i could use SQL Server Reporting Services. Later we found this from here
I wonder what is to generate a history burn down chart in excel or somewhere.
Thanks!
