On the home page, there is a simple chart "Last 7 Days Requests" that shows Open (red) and Closed (green) requests for the last 7 days of the week.

Is it possible to change this chart to another Dashboard object?

And the customer would like a very, very simliar graph, but with 4 colors, for example: Overdue (red), unassigned (yellow), Assigned and Open (green) and Closed (blue). Or something of the sort. I haven't found a way to do this with the Reports and Dashboards.

Any suggestions? thanks -Ricardo
