gnuplot-0.5.6: 2D and 3D plots using gnuplot

Graphics.Gnuplot.Simple

Description

This is a simple monolithic interface to gnuplot that can be used as is in GHCi or Hugs. We do not plan to support every feature of gnuplot here, instead we provide an advanced modularized interface in Graphics.Gnuplot.Advanced.

This was formerly part of the htam package.

data LineAttr Source #

Be careful with LineTitle which can only be used as part of gnuplot's plot command but not as part of set. That is,

plotList [LineStyle 0 [LineTitle "foobar"]] [0,5..100::Double]

will leave you with an invalid gnuplot script, whereas

plotListStyle [] (defaultStyle {lineSpec = CustomStyle [LineTitle "foobar"]}) [0,5..100::Double]

does what you want.

The Int types would be better enumerations but their interpretations depend on the gnuplot output type. :-(

epspdfPlot Source #

Arguments

:: FilePath 
-> ([Attribute] -> IO ())

Drawing function that expects some gnuplot attributes.

-> IO () 

Redirects the output of a plotting function to an EPS file and additionally converts it to PDF.

inclPlot Source #

Arguments

:: FilePath 
-> ([Attribute] -> IO ())

Drawing function that expects some gnuplot attributes.

-> IO String 

Creates an EPS and a PDF graphics and returns a string that can be inserted into a LaTeX document to include this graphic.

Different from GHCi, Hugs doesn't output a return value from an IO monad. So you must wrap it with a putStr. Nevertheless this implementation which returns the LaTeX command as string is the most flexible one.
