title: Module 'matplotlib.cm' has no 'Blues' member
body: <pre><code>import matplotlib.pyplot as plt
  
  x_value = range(1, 500)
  y_value = [x**3 for x in x_value]
  
  
  plt.style.use('Solarize_Light2')
  fig, ax = plt.subplots()
  ax.scatter(x_value, y_value,c = y_value,cmap = plt.cm.Blues, s = 5)
  
  ax.set_title('Square number', fontsize = 24)
  ax.set_xlabel('value', fontsize = 14)
  ax.set_ylabel('square of the value', fontsize = 14)
  ax.tick_params(axis = 'both',which = 'major', labelsize = 14)
  
  ax.axis([0, 540, 0, 125500000])
  
  plt.show()
  plt.savefig('otp.jpeg', bbox_inchs = 'tight')
  </code></pre>
  <p>The program runs correctly. it gives a blue color to the line but in the problems tab it shows that
  Module 'matplotlib.cm' has no 'Blues' member . so what is the possible solution</p>
