I've installed this mod on a client's site and it's working well except for 1 small issue. I noticed that on most of the sample sites posted in this thread, hovering over the different rows in the chart changes the background color of the selected row. That's not happening with my install and I don't see how it's different.
Here's a sample item:

Any idea what might be happening?
