title: How to change plot properties of statsmodels qqplot? (Python)
body: <p>So I am plotting a normal Q-Q plot using <a href="http://statsmodels.sourceforge.net/devel/generated/statsmodels.graphics.gofplots.qqplot.html" rel="noreferrer">statsmodels.graphics.gofplots.qqplot()</a>.</p>
  
  <p>The module uses matplotlib.pyplot to create figure instance. It plots the graph well. </p>
  
  <p>However, I would like to plot the markers with alpha=0.3. </p>
  
  <p>Is there a way to do this?</p>
  
  <p>Here is a sample of code:</p>
  
  <pre><code>import numpy as np
  import statsmodels.api as sm
  import matplotlib.pyplot as plt
  
  test = np.random.normal(0,1, 1000)
  
  sm.qqplot(test, line='45')
  plt.show()
  </code></pre>
  
  <p>And the output figure:
