title: Setting Yaxis in Matplotlib using Pandas
body: <p>Using Pandas to plot in I-Python Notebook, I have several plots and because Matplotlib decides the Y axis it is setting them differently and we need to compare that data using the same range.
  I have tried several variants on: (I assume I'll need to apply the limits to each plot.. but since I can't get one working... From the Matplotlib doc it seems that I need to set ylim, but can't figure the syntax to do so.</p>
  
  <pre><code>df2250.plot(); plt.ylim((100000,500000)) &lt;&lt;&lt;&lt; if I insert the ; I get int not callable and  if I leave it out I get invalid syntax. anyhow, neither is right...
  df2260.plot()
  df5.plot()
  </code></pre>
