I am keeping track of bug fixing for multiple projects, and would like to create graphs that show the total amount of created vs. the resolved issues on a weekly basis.
By total, I mean not just the amount of created vs resolved bugs during that week (like in the "created vs resolved graph"), but over the lifetime of the project. So for example, if the project had 100 created and 50 resolved bugs before the shown period in the graph, the graph should start with 100 created and 50 resolved bugs and show the progression from there throughout the shown period.
This way we could see how many bugs are in our database and how many of those are yet to be fixed, so we can easily see how much focus we should put on bug fixing.
Alternatively, I suppose I could use a graph that shows the amount of Open or Unresolved issues per day, although this wouldn't show the quantity of bugs being processed.
Is either of this possible?
