RE: Gradient on each bar rather than across entire graph

Yes, as you can see from the sample code the dataset index is passed in.
Then if you want to count what bar you are up to then you just have a member
var to do that, the class is called on every bar draw. I've done this when I
wanted the bar colour to change when I reached a 'future' date.
