  <p>I want to plot it:</p>
  
  <pre><code>df2[['width', 'height', 'depth']].head(20).plot.bar(figsize=(8, 8), fontsize=16)
  </code></pre>

  <p>Works great, but there I need increase amount of points of Y axis. I want to add numbers like 2400, 1900, etc. How can I do that? Why is there only 6 points on Y axis ?</p>
