title: Automatically saving plot, python, matplotlib
body: <p>I'd like to save my plot after it's finished. I've tried something like this:</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import os
  
  plt.ion()
  x = []
  y = []
  home = os.sep.join((os.path.expanduser('~'), 'Desktop'))
  home1 = home + '\nowy'
  
  for i in range(0,20):
      x.append(i)
      y.append(i+2)
  
      plt.plot(x, y, 'g-', linewidth=1.5, markersize=4)
      plt.axis(xmin = 0,xmax = 200,ymin=0,ymax=200)
      plt.show()
      plt.pause(0.1)
  plt.pause(5)
  plt.savefig(os.sep.join(home1 + '1'),format = 'png') 
  </code></pre>
  
  <p>But it does not work. Thers is an error:</p>
  
  <pre><code>[Errno 22] invalid mode ('wb') or filename: 'C\\:\\\\\\U\\s\\e\\r\\s\\\\\\M\\i\\c\\h\\a\\l\\\\\\D\\e\\s\\k\\t\\o\\p\\\n\\o\\w\\y\\p\\l\\o\\t\\1.png'
  </code></pre>
  
  <p>Can anyone tell me how to save this plot exactly in direction "home1", please? I've serched for sollution for a while but nothing worked.</p>
