title: Modifying axis labels for pandas bar plot
body: <p>I'm having difficulties adding percentages to my y-ticks.  My total plot area includes 2 different plots, one is plotting percentages (df1), the other is not (df2).  I've tried a variety of solutions I've found here on stackoverflow and other sites, but haven't had any luck.</p>
  
  <pre><code>
  import pandas as pd
  
  df1 = pd.DataFrame([80.18, 50.0, 72.3, 90.1, 87.7])
  df2 = pd.DataFrame([1000, 2000, 3000, 4000, 5000])
  
  
  
  fig, axes = plt.subplots(nrows=1, ncols=2)
  
  df1.plot.bar(ax=axes[0], title = "this", figsize=(8,8), legend=False)
  
  df2.plot.bar(ax=axes[1], title="that", figsize=(8,8), legend=False)
  
  </code></pre>
  
  <p>Any help is appreciated</p>
