title: Simple 2D graph drawing - PostScript
body: <p>Can you tell me an easy way to draw <code>graph(2+x, sin(x), cos(x+3)/3.....)</code> in PS format?</p>
  
  <p>For example, I want to draw <code>f(x) = 2+x</code>, with the following values:</p>
  
  <pre><code>Table of values: 
  Value of X = -5 | -4 | -3 | -2 | -1 | -0 | 1 .....
  Value of Y = -3 | -2 | -1 |  0 |  1 |  2 | 3 .....
  </code></pre>
  
  <p>How to draw this graph? Draw lineto, draw polygon or use curve command?
  What do you think is the best solution?</p>
