title: Matplotlib marker text changes size based on number of characters how can I figure out why
body: <p>marker font seems to have a sizing algorithm dependent on length. I want to research this myself BUT don't know where to start? The code line is below and I send about 12 symbols to it and the font size changes. How do I step through this problem and find the root cause for it please?</p>
  
  <pre><code>plt.plot(x,y,lw=2.5,color='g',linestyle='solid',marker=r"$\mathsf{%s}$" % symbol, markersize=30,
       markeredgewidth=1, markeredgecolor='k' , markerfacecolor= 'None')
  </code></pre>
  
  <p>here is the output from sending 12 different symbols to it ie AAPL, AIG,C </p>
