Graph only for outstanding tickets

Graph only for outstanding tickets

Hi all,

I am still trying to get my head around SDP, but I am looking at creating a simple 2D Bar graph with the following fields.

Any ticket that is not resolved or closed up to 30 days
Same as above but is between 31 and 60 days
Same as above but is between 61 and 90 days
Same as above but is greater than 91 days

Grouped by Technician.

Thank you for any feedback.
