title: How to display a text with matplotlib
body: <p>I would like to do this :</p>
  <p>I have this python code :</p>
  <pre><code>import numpy as np
  import pylab as plt
  
  a = np.array([1,2,3,4,5,6,7,8,9,10])
  b = np.array([7,8,6,3,2,1,5,8,4,15])
  c = plt.plot(a,b,'.')
  d = 5
  plt.text(2,3, &quot;d = &quot;+d) #This line is the problem because i have not the value of d !
  plt.show()
  </code></pre>
  <p>So actually I just want to display the value of d and also I want to display the value of d but relatively for instance at the bottom right but not with some coordinates. Is it possible to do this with Python ?</p>
