title: Two Gaussian distribution plot on the same axis
body: <p>I am trying to plot two Gaussian distribution both with mean zero, one with variance 1 and the other with variance 2 on the same axis. Here is my code.</p>
  
  <pre><code>X= 0 + 1.*randn(2,500);
  plot(X(1,:),X(2,:),'x');
  hold on
  %plot(m(1),m(2),'r*')
  Y= 0 + 2.*randn(2,500);
  plot(Y(1,:),Y(2,:),'gx')
  </code></pre>
  
  <p>Please check and see if i have done it correctly. I also want to have them in 2-D plot and superimpose.</p>
  
  <p>Thanks.</p>
