Hi, The rationale behind developing the plot package is a desire to target users as well as programmers. The plot interface provides monadic construction of figures, very similar in style to the way a gnuplot script or matlab script/function would be structured (especially with the Simple interface). I am looking forward to being able to use GHCi instead of matlab, and the plot-gtk companion package provides a way to incrementally update a plot on screen. I think that this is where the design difference occurs. Looking at the Chart interface, I was confronted with myriad data types and functions. Yes, the plots look nice, but, as I have been told, the Chart interface can be overwhelming for a mathematics user cf. haskell programmerr. Also, the plot package uses Pango, so unicode should work out of the box (for greek symbols and the like). Cheers, Vivian On 1 October 2010 18:24, Ivan Lazar Miljenovic wrote:

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. The plot 0.1.1 package supports candle and whisker charts.

http://hackage.haskell.org/plot

That URL should of course be http://hackage.haskell.org/package/plot

However, I'm curious: what is the rationale behind you developing plot rather than you helping Tim extend Chart?
