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
