Cumulative Flow Diagram showing downward band

Question

I am new to JIRA Cumulative Flow Diagrams and have reached a hurdle I can't seem to understand.

All the documentation I can find states there is something wrong with your diagram if you see "bands going down", and that somehow the diagram has not been constructed properly

This is a snapshot from our current CFD:

Can anyone help me understand what I need to look for to understand the downward bands in the above?

Hi @Niki Barile , i think I found a possible scenario where the graph is going down. It happens when you move Tickets back to where they were before. Jira counts that as sort of a subtraction.

I guess the same would apply when you completely delete a ticket. But I haven't tried that one.

Hope that helps also everyone else, having that "issue"

Conclusion: never move your tickets left! It messes up your CFD

Hi @Niki Barile , I'm experiencing the same and wonder when it is the case.

Have you found the answer? And if, how did you find out what was going on?

Cheers,
