title: How to customize marker/symbol properties in matplotlib?
body: <p>Example command:</p>
  
  <pre><code>prop = matplotlib.pyplot.scatter(x,y,s=s,c=c)
  </code></pre>
  
  <p><code>dir(prop)</code> shows set_edgecolor, set_edgecolors, set_linestyle, set_linestyles - why so many variations on the same thing?</p>
  
  <p>Also, how do I remove the edgecolors? Setting values to <code>None</code> does nothing. And how do I change the marker size after the plotting? There does not appear to be a markersize attribute that I can access...</p>
  
  <p><strong>Edit</strong></p>
  
  <p>If the symbols are generated through <code>plyplot.plot</code>, there is a markersize attribute to change it seems. But with <code>pyplot.scatter</code>, not present.</p>
