title: Python & Matplot: how to set auto-offset?
body: <p>For example, when I try to plot points</p>
  <pre><code>points = [(0,0),(0,1),(1,1,),(1,0)]
  for point in points:
      plt.plot(point[0], point[1], 'o')
  plt.show()
  </code></pre>
  <p>It will display</p>

  <p>This makes the points hard to see. How can I make the <code>x</code>, <code>y</code> axis wider so the point would move to the center of the plot? Something like</p>

  <p>That is, how can I set the <code>offset</code> value of the points to the bounderies of the <code>plot</code>, so they won't be displaed at corners?</p>
