SSRS: Convert this matrix into a chart?

I have this SSRS report, which is basically a matrix, and it's composed of Sum(Fields!Down.Value) (report detail), EmpId (rows), andHour, Minute (columns). I've included a screenshot below.

As you can see most of the values are 0, so I would like to convert that into a chart that will display any differences in a 24-hour day. The graphic will display exactly the same  thing, but nicer. So, on a quick view, one can easily see that EmpId2A_1 had a red flag of 68 (anything value over 0) at 7:30. When I hover the cursor over2A_1 at 7:30, the user will see value 68.

Any help is appreciated.
