This is my first time using a RadHtmlChart and I have almost exactly what I need, but the final piece of the puzzle is eluding me. Below is what I'm trying to achieve. It's the red line I'm trying to get. Ideally I would also like the line labeled "Target", but I can live without that. I don't care how it's done. Turning the 90% line red, adding a line over the 90% line, adding another field to my SQL query if that would work, or pretty much any solution that will get me there.
