Why doesn't our burndown chart show a "drop" when stories change from to-do to done ?

[Richard McGhee]

Our burndown chart is not responding to stories being completed.  Meaning, we are changing story status from "To Do" to "Done but see no "Drop in the burndown line.  Only see the trend line with no change in the actual burn down line. (it should be dropping as stories are completed., right?)

Hi @Richard McGhee 

And you have started the sprint?
And is the Done status the right-most column on your board?

Kind regards,
Dick

Hi @Richard McGhee

Is this board filter query will show done issues in result?
Is the board using the right estimation field?
