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

ruby-mathgl's Issues

can't find c++ header

Hi,

    % ruby extconf.rb
    checking for mgl2/type.h... yes
    checking for mgl2/data.h... no
    *** extconf.rb failed ***
    ...

The "mgl2/data.h" contains the line "#include ", this is a header file of C++, not C.

I don't know right way, but when I Add with_cflags(" -x c++ ") block, just fine.
Patch attached.
