Group by "changed by" in a pie chart

[mfouad]

I want to make a pie chart showing all people who closed an issue and then it was reopened.

The problem is the fields I see contains current assignee not the one who closed it before as I can do in the filter "Changed from a to b BY x".

I want to get this "x" as a statistic field in the pie chart. I also don't want to create a custom field for the issues since it can be changed by anyone and it is already exist in the data (I can filter with it)

You could use a custom field (e.g "Closer") and fill that in on the Post Function of the transition to Closed/Done. Use the Update issue custom field and the %%CURRENT_USER%% to fill in this custom field. Then you can use the custom field in the pie chart. Should work.
