How do I make sure that my burn down charts only reflect the issues in the respective sprint?

[Johannes Klaiber]

When I look at my burndown charts the left axis of the chart (amount of story points remaining) shows all tickets that I put in any sprint so far and adds them up. 
e.g. the sum of story points of my sprint is 70. So I expect the burndown chart to start at 70 and then go down accordingly. However this number is around 300 which is approx. the sum of all story points of all tickets ever worked on. 

See screenshot attached:

It seems to me that the burndown chart is taking the wrong statuses into account - or somehow my tickets are never "done" although they are.

Thanks for help!

Hello @Johannes Klaiber

Thank you for reaching out.

Indeed, the Burndown Chart should only consider the Story points of the issues added in the Sprint you selected for being displayed, not the issues from different Sprints. 

That being said, I believe you might be missing the conclusion of your issues when finishing your sprints, so the issues are being dragged to the next sprint although you moved them to its final status.

To properly diagnose it, I suggest you try the following:

1 - Go to your Issue Navigator page and run the following query, replacing "Sprint1" with the current Sprint you are selecting in your Burndown Chart:

Sprint = "Sprint1"

2 - Make sure you followed the steps below for the issues returned when moving them to "resolved":

1 - Moved the issues to the right-most column of your board, as described in this documentation:

The Burndown Chart is based on your board's column mapping. An issue is considered to be 'To Do' when it is in a status that has been mapped to the left-most column of your board. Similarly, an issue is considered to be 'Done' when it is in a status that has been mapped to the right-most column of your board. 

2 - Added them with a valid resolution, which you can confirm by adding the parameter "Resolution is not empty" in the query.

Let us know if you have any questions.
