I'd like to have a bar graph in zoho reports of my service desk tickets whereby I can see two totals. First total is the number of tickets opened in the current month, which is easy. But in addition, I'd like to see the total number of tickets closed in the same month BUT regardless of whether or not they were opened that month.

For example 100 tickets are opened in October. That's the first total. The second total could be 120 tickets closed in October because 20 of those were opened in September. I want to limit the first total to tickets opened in a single month, but not the second total. The second total should be limited by tickets closed in a single month.
