How to show the Year Report where Month wise Job Run count should display

How to show the Year Report where Month wise Job Run count with status of Jobs should display.
I tried to use Group by …But some months have 31 days some months have 30 days, So I cant put 30d in Group By, How to handle this?
I used Postgresql as Data Source

Kindly Please help.

Thanks,
Rajesh

Here Group by Interval I have put 31d, However different months will have different number of days like 30d, 29 days…So please let me know whether we have option to show month basis count …
like Group by time(1Month,none)

Thanks,
Rajesh
