Trying to use "View work items as charts" feature. In our filter view we are able to create charts based on "Story points" but I don't see "Original Estimate" and "Remaining Estimate" fields in the drop down menu and hence I'm not able to create charts based on these data points. These fields are set to visible in issue screens, I can see them in the filter table but it still doesn't appear in the "Chart settings" column drop down menu. Any pointers to fix this issue is much appreciated.
