HLearn.Models.Distributions.Visualization.Gnuplot

This module contains the functions for plotting distributions using Gnuplot.

Main interface

plotDistribution :: PlottableDistribution dist => PlotParams -> dist -> IO ()

Call this function to plot your distribution. You can create the PlotParams manually, or you can use default parameter creating function below.

Plot parameters

Internal

class (Plottable (Datapoint dist), Plottable (Probability dist), Num (Probability dist), PDF dist, MaybeShow (Datapoint dist)) => PlottableDistribution dist where

In order to plot a distribution, it must be an instance of this class. You shouldn't need to know the details.

Methods

samplePoints :: dist -> [Datapoint dist]

plotType :: dist -> PlotType

pdfL :: dist -> [Probability dist]

plotdata :: dist -> String
