title: remove main title from histogram in pandas
body: <p>I want to remove &quot;SalesPrice&quot; from the plot.
  and remove the borders (keep the x,y axes and remove the top border)
  and I want to convert the numbers to be written with (e).
  I will be grateful for any help.</p>
  <pre><code>salesHist = ames.hist(column='SalePrice', grid = False, edgecolor = 
  &quot;black&quot;, color = 'khaki')
  
  for ax in salesHist.flatten():
     ax.set_xlabel('home sale price')
     ax.set_ylabel('Density')
  </code></pre>
