Help with Monthly Data Entry

Help with Monthly Data Entry

I want to be able to view expected revenue by month on a graph in Creator, but I noticed that when I make a graph view, it plots by specific date.

Is there a way we could change add a feature to the graph report that will capture all data for a given month and create a vertical bar for "August" rather than one bar for August 12 and another bar for August 25?

Thanks.
