burndown chart zero points

[Lena M.]

Hi!

Though we estimate our stories, our burndown chart ist just constant zero. It stays like that the whole sprint and this doesn't change if we close the sprint. See the images attached.

We do not estimate subtasks. But at least some bigger steps should be shown, no?

Thanks in advance!

I found the culprit:

Boardconfiguration > Estimation > Time Tracking

after I chose "none" here, we have a normal burndown chart!
