Graphics.Rendering.Chart.Easy

Description

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]))

line :: String -> [[(x, y)]] -> EC l (PlotLines x y) Source

Constuct a line plot with the given title and data, using the next available color.

points :: String -> [(x, y)] -> EC l (PlotPoints x y) Source

Construct a scatter plot with the given title and data, using the next available color and point shape.

bars :: (PlotValue x, BarsPlotValue y) => [String] -> [(x, [y])] -> EC l (PlotBars x y) Source

Construct a bar chart with the given titles and data, using the next available colors

setColors :: [AlphaColour Double] -> EC l () Source
