title: How to draw a dashed line using Matplotlib's ConnectionPatch?
body: <p>How can I change the linestyle of the line drawn by the ConnectionPatch? It would be best if the usual linestyles ":", "--", or "-" would work. The ConnectionPatch code I was using is:</p>
  
  <pre><code>con = ConnectionPatch(color=seas_col[iseas],linewidth=2,
     xyA=(mean_vals_1[isn,iseas],0), 
     xyB=(mean_vals_2[isn,iseas],3000), 
     coordsA="data", coordsB="data",
     axesA=axarr[0], axesB=axarr[1])
  </code></pre>
  
  <p>Both the arrowstyle and connectionstyle don't accept the above mentioned styles.</p>
