title: remove white background from the matplotlib graph
body: <p>I am trying to plot the transparent graph, but some boxes are appearing in the background and outer frame is not coming. How can I remove the white background from the plot and make it transparent and put outer frame? </p>
  
  <pre><code>from matplotlib import pyplot
  pyplot.scatter(Neural_Net, y_test)
  pyplot.xlabel('Actual', fontsize=15)
  pyplot.ylabel('Predicted', fontsize=15)
  pyplot.show()
  </code></pre>
