title: Python matplotlib superimpose scatter plots
body: <p>I am using Python matplotlib. i want to superimpose scatter plots. I know how to superimpose continuous line plots with commands:</p>
  
  <pre><code>&gt;&gt;&gt; plt.plot(seriesX)
  &gt;&gt;&gt; plt.plot(Xresampl)
  &gt;&gt;&gt; plt.show()
  </code></pre>
  
  <p>But it does not seem to work the same way with scatter. Or maybe using plot() with a further argument specifying line style. How to proceed?
  thanks</p>
