title: How to reduce the space between barh plot while maintaining the width
body: <p>I cannot find the proper parameter to modify in Matplotlib documentation.</p>
  
  <p>I have this:</p>
  
  <pre><code>df.plot(kind='barh',x='Attributes',y='Counts', ax=ax1, color='#C0C0C0', width=0.3,legend= False)
  </code></pre>
  
  <p>which produces an horizontal bar plot.</p>
  
  <p>I want to mantain the width = 0.3 but reduce the space between the bars. </p>
