View source for OCaml tutorial

== Intro ==

The [http://caml.inria.fr OCaml] bindings for PLplot provide three means of accessing PLplot's functionality through three modules, Plplot, Plplot.Plot and Plplot.Quick_plot.  In versions 5.9.6 and later the OCaml sections of the [http://plplot.sourceforge.net/documentation.php PLplot documentation] includes a tutorial which introduces each of these modules.  This tutorial is meant to expand on that material and allow for a simpler process for contributing improvements.

== Using the Quick_plot module ==

The main OCaml PLplot module is meant to be open'd:

  open Plplot

From here, one can try out a quick plot of sin and cos:

  Quick_plot.func [sin; cos] (-3.14, 3.14)

which gives output which looks something like this:

That's great, but it would be even better if there were labels so that we know what the axes mean and a legend to show which line corresponds with which function. We can do that:

  Quick_plot.func
    ~labels:("Angle (radians)", "Amplitude", "A few functions")
    ~names:["sin"; "cos"]
    [sin; cos] (-3.14, 3.14)

with output which looks something like this:

Much better, and much easier to interpret!
