Change Trend Report - Annual Period by Month Breakdown

[Gary Pallas]

Is it possible via the 'create new report' to create a report that articulates number of completed changes in a year period broken down with outcome status and values by month to obtain a trend (both of these will be custom fields)?  I can generate totals for the year via a dashboard but I'm keen to split this by month for trend reporting. 

I can't see any options to do this unless there is specific JQL query syntax (I'm very much a novice) that adds this configuration. 

Appreciate any help as I'm sure others have walked this path

Thank you all
