Sprint report shows flat red line even though issues are being closed within the sprint

[Vish Shetty]

Hi,

 I need some help in resolving/understanding why I am only seeing a flat red line for the sprint report.  The tickets have the estimates (story points) entered prior to starting the sprint, the issues are closed during the sprint but I still see a flat red line until the last day of the sprint when I close the sprint.

I checked the estimation configuration for the board, the estimation statistic is set for story points and time tracking to none. I verified that both the status and resolution is marked as done within the sprint.

Can someone give me pointers as to what I am doing wrong and what I need to look for to address this issue.

Thanks
