Question

I have a CPTTradingRangePlot with a CPTTradingRangePlotStyleCandleStick style.

I’m looking for a way to highlight a specific (or a few) candlesticks with a different fill color (or a glow, or something), but I can’t find a way to access individual candlesticks in a similar way that a CPTBarPlot has with -(CPTFill *)barFillForBarPlot:(CPTBarPlot *)barPlot recordIndex:(NSUInteger)index;

Am I missing something here?
Can I somehow maybe access a specific candlestick after the data load, and then change the fill color?

I was also thinking about adding an Annotation Layer, and maybe draw a circle around the specific candlestick(s), but I don’t want to use an image, since it will get stretched and pixelated when I’ll adjust it’s size.
Is there any way to draw a vector-based shape as an annotation around the candlesticks?

Thanks for any help!

You can put a request for that feature on the Core Plot issue tracker. In the meantime, you can achieve the same look by using more than one plot, one for each different style.
