Graphics.Rendering.Chart.Easy

A high level API for generating a plot quickly.

Importing the Easy module brings into scope all core functions and types required for working with the chart library. This includes key external dependencies such as Control.Len and Data.Colour. The module also provides several helper functions for quickly generating common plots. Note that chart backends must still be explicitly imported, as some backends cannot be built on all platforms.

Example usage:

import Graphics.Rendering.Chart.Easy
import Graphics.Rendering.Chart.Backend.Cairo

signal :: [Double] -> [(Double,Double)]
signal xs = [ (x,(sin (x*3.14159/45) + 1) / 2 * (sin (x*3.14159/5))) | x <- xs ]

main = toFile def "example.png" $ do
    layout_title .= "Amplitude Modulation"
    plot (line "am" [signal [0,(0.5)..400]])
    plot (points "am points" (signal [0,7..400]))
