Burndown chart is not displaying the estimations .

[mallikarjun kalal]

We have started a sprint without  estimations after start of the sprint we changed the estimations . So burndown chart is not displaying the estimations .

Is there any troubleshooting steps to get proper reports for all estimations?

If we close the  existing sprint  and if We start another sprint with same Start Date: and End Date of sprint as existing sprint . also moving all issues to new sprint from  existing sprint. Will those Original Estimates reflect in the new sprint ?

 or 

 Is there any other better solution to get proper report for below issue ?

I suggest closing that Sprint and just start a fresh new one. The old one will be unusable anyway.
