title: Change y-axis scaling fontsize in pandas dataframe.plot()
body: <p>I am changing the font-sizes in my python pandas dataframe plot. The only part that I could not change is the scaling of y-axis values (see the figure below).</p>
  
  <p>Could you please help me with that?</p>
  
  <p>Added:</p>
  
  <p>Here is the simplest code to reproduce my problem:</p>
  
  <pre><code>import pandas as pd
  
  start = 10**12
  finish = 1.1*10**12
  y = np.linspace(start , finish)
  pd.DataFrame(y).plot()
  plt.tick_params(axis='x', labelsize=17)
  plt.tick_params(axis='y', labelsize=17)
  </code></pre>
  
  <p>You will see that this result in the graph similar to above. No change in the scaling of the y-axis.</p>
