title: Is there a python equivalent for "Screen Reader" in Origin Software?
body: <p>I am plotting two graphs on the same curve. Code goes something like this :</p>
  
  <pre><code>x = np.array([86,14,19,24,30,55,41,46])
  y1 = np.array([96,86,82,78,80,101,161,32])
  y2 = np.array([54,54,48,54,57,76,81,12])
  y4 = np.concatenate([y2.reshape(8,1),y1.reshape(8,1)],1)
  plot(x,y4)
  </code></pre>
  
  <p>I need values at some points other than in <code>x</code> array. For example:
   for values 30,50 and 78.</p>
  
  <p>There is an option to read the data from graph in Origin using "Screen Reader" (i.e. when I point in the graph, I get the value.).</p>
  
  <p>Is there an equivalent in python?</p>
  
  <p>.plot is matplotlib.plot</p>
