I'd like to request an additional chart. Our group basically uses a chart that tracks the total open issues (this includes re-opens, in progress etc...) vs. Resolved issues (this includes resolved and closed tickets).
In general the chart will look sort of like an X with a high number of Open issues and as the project nears completion, it will be near Zero whereas the Resolved Line will move toward the upper right hand corner of the chart.
I think this chart can be very similar to the Created v. Resolved issues Report with the exception that you can more accurately see how many tickets are still open for a particular release.
I've attached an example of the chart.
