title: Edit the width of bars using dataframe.plot() function in matplotlib
body: <p>I am making a stacked bar plot using:</p>
  
  <pre><code>DataFrame.plot(kind='bar',stacked=True)
  </code></pre>
  
  <p>I want to control width of bars so that the bars are connected to each other like a histogram.</p>
  
  <p><em>I've looked through the documentation but to no avail - any suggestions? Is it possible to do it this way?</em></p>
