title: Sympy: Set aspect ratio
body: <p>I'm using Spyder's Ipython console to try to get some quick parametric plots of functions.  For now I'm focusing on x = cos(t), y = sin(t).  I ran the command </p>
  
  <pre><code>import sympy as sp
  sp.init_session()
  p = plotting.plot_parametric(cos(t),sin(t),(t,0,2*pi))
  </code></pre>
  
  <p>and I get an oblong plot of the curve.</p>
  
  <p>If I enter</p>
  
  <pre><code>p.aspect_ratio = (1,1)
  p.show()
  </code></pre>
  
  <p>nothing changes.  I try other aspect ratios and still nothing changes. </p>
  
  <p>After looking at this answer <a href="https://stackoverflow.com/questions/36505768/in-sympy-plotting-how-can-i-get-a-plot-with-a-fixed-aspect-ratio">In sympy plotting, how can I get a plot with a fixed aspect ratio?</a></p>
  
  <p>I tried following their instructions to try to leverage matplotlib and I get no errors.  But when I enter </p>
  
  <pre><code>plt.show() 
  </code></pre>
  
  <p>nothing shows.  </p>
