title: Finding coordinates of a point in a graph
body: <p>I have generated a scatter plot using python.</p>
  
  <p>How to find out the coordinates of a point?</p>
  
  <pre><code>from matplotlib import pyplot as plt
  
  x = [min(max(L2.real, 0.2), 0.3) for L2 in L]      
  
  y = [min(max(L2.imag, 0), 0.004) for L2 in L]
  
  plt.scatter(x, y)
  
  plt.show()
  </code></pre>
