  <p>My code for this was :</p>
  
  <pre><code>jacaardMatrix = 1.662887377173091485e-01    3.432835820895522305e-01    3.568320278503046006e-01
  5.065963060686015651e-02    3.160270880361173984e-01    3.374888691006233121e-01
  3.093987157034442520e-02    1.802120141342756221e-01    1.748178980228928259e-01
  
  
  fig2=plt.figure()  
  plt.title("Radius and FRC Jacaard Values for Scoring System: "+str(i))
  plt.xlabel('Radius')
  plt.ylabel('FRC Size')
  plt.imshow(jacaardMatrix)
