On a project dashboard in JIRA, one of the default graphs is a Unresolved Project Issues by Priority graph. I would like to be able to display this same graph in Confluence through a JIRA gadget without having to setup and filters or write a custom gadget.
It seems JIRA already has a default filter enabled for this, however, it is not exposed as a current JIRA Gadget in Confluence.
Is there a way to tap into that existing filter or graph through the JIRA gadgets in Confluence or by some other means?
The top left graph in the image below is the one I am after.

As I have MANY projects, I don't want to have to setup a filter for each project if I can help it.
Thanks for the help.
