You could use a dashboard to show each of the three metrics aligned over the same month/year combination. It isn't clear if the date ranges are supposed to be inclusive of the closed/opened events outside of the last 12 months.
I made a sample workbook with a dashboard to show one method of doing this. Note that I did this quickly and did not add in headers for each metric but instead just wanted to highlight a method of building a dashboard when trying to compile a view with different measures and conditions for each measure in the view.
