title: Adding percent sign in middle of a label while using scientific styling
body: <p>I am trying to put a y-label on my plot for titanium oxide, my label has to be like this: <a href="https://i.stack.imgur.com/CXWGR.png%7D" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CXWGR.png%7D" alt="Desired plot label"></a></p>
  
  <p>How do I manage to keep the scientific styling while putting the percent sign, I have tried the following which doesnt seems to work</p>
  
  <pre><code>plt.ylabel('{0} %\n'.format('$TiO_2 (wt') + ')$')
  </code></pre>
