title: How do I increase the infinity symbol in matplotlib labels
body: <p>Consider the illustrative example below:</p>
  
  <pre><code>from matplotlib import pyplot as plt
  
  x=list(range(5))
  xticks=x.copy()
  xlabels=x.copy()
  xlabels[-1] = r"$\infty$"
  
  fig, axes = plt.subplots()
  
  axes.plot(x)
  axes.set_xticks(xticks)
  axes.set_xticklabels(xlabels, fontsize=20)
  </code></pre>
  
  <p>This produces the following figure</p>
  
  <p><a href="https://i.stack.imgur.com/EnKjF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EnKjF.png" alt="enter image description here"></a></p>
  
  <p>I want to make the infinity sign larger in relation to the numbers in the x labels. It is too small in the way matplotlib plots it. Everything that I've tried to increase its size also increases the sizes of the numbers in the label.</p>
  
  <p>How can I do that?</p>
  
  <p>Thanks</p>
