# Ruby/MathGL

Ruby wrapper of [MathGL](http://mathgl.sourceforge.net/), made using SWIG.

MathGL is a library for scientific data visualization developed by Alexey Balakin.

(This package is under construction.)

## Installation

1. Install MathGL2 library: http://mathgl.sourceforge.net/

2. Install Ruby/MathGL from source:

        ruby setup.rb config -- --with-mathgl-dir=/usr/local
        ruby setup.rb setup
        ruby setup.rb install

   Or install with gem:

        gem install mathgl -- --with-mathgl-dir=/usr/local

## Usage

Write a plot to PNG file:

    require 'mathgl'

    prc = proc{
      x = (0..100).map{|i| i*0.1}
      y = x.map{|i| Math.sin(i)}
      set_ranges(0,10,-1,1)
      box
      axis
      plot(x,y)
    }

    gr = MathGL::MglGraph.new
    gr.instance_eval(&prc)
    gr.write_png("test.png","",false)

Display a plot on Qt window:

    require 'mathgl'

    prc = proc{
      x = (0..100).map{|i| i*0.1}
      y = x.map{|i| Math.sin(i)}
      set_ranges(0,10,-1,1)
      box
      axis
      plot(x,y)
    }

    qt = MathGL::MglQT.new(&prc)
    qt.run
