title: Tableau: stacked side-by-side bars with two different dimensions splitting the columns
body: <p>I am trying to create a stacked side-by-side bar chart over time with 2 measures:</p>
  
  <ul>
  <li>Total Calls (Split by type of a call)</li>
  <li>Requests (Split by type of a request)</li>
  </ul>
  
  <p>I have reached a point where I can get this view:
  <a href="https://i.stack.imgur.com/G9LDQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/G9LDQ.png" alt="Current chart"></a></p>
  
  <p>I am struggling with getting 'Calls' bar colored by the call type, and Requests by the its own type, to ultimately receive this:</p>
  
  <p><a href="https://i.stack.imgur.com/cK2et.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cK2et.png" alt="expected outcome"></a></p>
  
  <p>(purple colors: types of calls, red-orange-blue colors: types of requests. </p>
