title: Syntax for matplotlib parameters on a pandas hist
body: <p>According to the <a href="https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.hist.html" rel="nofollow noreferrer">docs</a>, the pandas hist method to create a dataframe can take a parameter <code>ax</code> to presumably pass some kind plotting parameters to the <code>ax</code> object. What I want to know is how I pass these parameters.  Here is some code:</p>
  
  <pre><code>import pandas as pd
  import numpy as np
  df = pd.DataFrame(np.random.normal(0,100,size=(100, 2)), columns=['col1', 'col2'])
  pd.DataFrame.hist(df,column='col1', ax={ylim(-1000,1000), set_title('new title')})
  </code></pre>
  
  <p>The above code seeks to modify the y-axis limits and title using the <code>ax</code> parameter, but I'm not sure of the syntax to use.</p>
