Hi - 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 I will use Finance-Quote-Yahoo to get the quote data from Yahoo. thanks for all your help.

You might try the gnuplot package as interface to the gnuplot program. There was already someone who wanted to plot candle sticks: http://projects.haskell.org/pipermail/gnuplot/2010-April/000009.html
Can I just do cabal install gnuplot or should I use darcs to get the
candles version..

I am trying to compile demo.hs, but keep getting the error that
Paths_gnuplot could not be found. What/where is paths_gnuplot?? Sorry,
I am still a beginner..

The Hackage version should be up to date now.

I forgot to mention in the documentation that you have to install with $ cabal install -fbuildExamples gnuplot in order to get the Demo compiled and the example data file installed.

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!). Tim

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
