  <p>I want to do three things to get it to show like 
  <a href="https://i.stack.imgur.com/isjCZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/isjCZ.png" alt="Expected outcome"></a></p>
  
  <ol>
  <li>Remove the Trend line on the scatter portion</li>
  <li>Show distinct demarcations of bars on the histogram plot</li>
  <li>Remove the curves on the histogram plots.</li>
  </ol>
  
  <p>Adding 'edgecolor' only demarcates the circles on the scatter plot, not the histogram.</p>
  
  <p>Any help is appreciated.</p>
