title: ECDF in python without step function?
body: <p>I have been using ECDF (empirical cumulative distribution function) from statsmodels.distributions to plot a CDF of some data. However, ECDF uses a step function and as a consequence I get jagged-looking plots. </p>
  
  <p><img src="https://i.stack.imgur.com/tTZM7.png" alt="enter image description here"></p>
  
  <p>So my question is: Do scipy or statsmodels have a ECDF baked-in without a step function? </p>
  
  <p>By the way, I know I can do this:</p>
  
  <pre><code>hist, bin_edges = histogram(b_oz, normed=True)
  plot(np.cumsum(hist))
  </code></pre>
  
  <p>but I don't get the right scales.</p>
  
  <p>Thanks!</p>
