More fun with Haskell plotting: Functions of functions

Posted 04-08-2013 at 12:56 AM by hydraMax (Bits and Pixels)

Code:
import Graphics.Gnuplot.Simple
f x a = (x + a) * (x - a) * (x + 2*a)
fs f l = map f [1..l]
main = plotFuncs
         [Key Nothing, Title "(x + a)(x - a)(x + 2a) for a over 1..10"]
         (linearScale 1000 (-10,10))
         (fs f (10 :: Double))
See attached graph.
