Hi, I'm trying to do some custom skinning to a line chart and am wondering if this is possible. We want to have all of the points along a line series be different colors based on the y value. It looks like when setting the pointstyle in seriesAtIndex delegate method, that I can only set a universal style per series. To help explain what I'm looking to do, I've attached an image of our mockup for this graph. Any advice would be appreciated. Thanks.
