Reports - Getting Nulls to Show as 0's In Report for Grouping Purposes

Looking to put together a report that displays various data points by month - like the number of opportunities closed, etc.

The problem with the Reporting module is that there seems to be no way for me to set it such that, if 0 opportunities were closed in April, show 0 instead of ignoring the April “group” altogether.

Does anyone know any solutions for this?

Having this functionality would hugely improve our data and graphs.

Unfortunately there is no way the reports can fill in missing Months. You can either develop a custom report based on your criteria or maybe try KReports which does allow to have custom queries where you can put 0 condition if not data found for the month.
