What are the libraries to use in Haskell to generate a stock candlestick chart like http://stockcharts.com/h-sc/ui?s=SPY&p=D&b=5&g=5&id=p05007254056
The chart library: http://hackage.haskell.org/package/Chart doesn't currently have support for candlestick charts, but adding support would be straightforward - a patch would be most welcome (hint, hint!).
I have a patch for Chart, adding candles as a new plot type. Patch attached, together with a PNG of some demo output. (patch containing demo/test to follow.) Regards, Malcolm
