Histograms

data PlotHist x y

Constructors

PlotHist

Fields

• _plot_hist_title :: String

  Plot title

• _plot_hist_bins :: Int

  Number of bins

• _plot_hist_values :: [x]

  Values to histogram

• _plot_hist_no_zeros :: Bool

  Don't attempt to plot bins with zero counts. Useful when the y-axis is logarithmically scaled.

• _plot_hist_range :: Maybe (x, x)

  Override the range of the histogram. If Nothing the range of _plot_hist_values is used.

  Note that any normalization is always computed over the full data set, including samples not falling in the histogram range.

• _plot_hist_drop_lines :: Bool

  Plot vertical lines between bins

• _plot_hist_fill_style :: FillStyle

  Fill style of the bins

• _plot_hist_line_style :: LineStyle

  Line style of the bin outlines

• _plot_hist_norm_func :: Double -> Int -> y

  Normalization function

Instances

Default (PlotHist x Int)

Methods

def :: PlotHist x Int

histToPlot :: (RealFrac x, Num y, Ord y) => PlotHist x y -> Plot x y

Convert a PlotHist to a Plot

N.B. In principle this should be Chart's ToPlot class but unfortunately this does not allow us to set bounds on the x and y axis types, hence the need for this function.

defaultPlotHist :: PlotHist x Int

The default style is an unnormalized histogram of 20 bins.

defaultFloatPlotHist :: PlotHist x Double

defaultPlotHist but with real counts

defaultNormedPlotHist :: PlotHist x Double

defaultPlotHist but normalized such that the integral of the histogram is one.
