title: multivariate numpy does not plot a normal distribution please help correct the mistake
body: <p>Multivariate numpy package numpy.random.multivariate_normal..does not return a normal distribution plot...the example given at the site.</p>
  
  <pre><code>import matplotlib.pyplot as plt
  x,y = np.random.multivariate_normal(mean,cov,5000).T
  plt.plot(x,y,'x'); plt.axis('equal'); plt.show()
  </code></pre>
  
  <p>When plotted does not give the normal distribution curve. I am new to numpy and I want to get a normal distribution curve..so please help.
  I want to plot x, y and normal pdf in 2-dimension. That is, I want to show that x and y follow , "multivariate" normal distribution.</p>
