title: Display users online using a pivot chart based on login and logout
body: <p>I have the following table:</p>
  
  <pre><code>Id      Status     Date    
  A      Log in   01.01.2018  01:44:03
  A      Log out  01.01.2018  02:57:03
  C      Log in   01.01.2018  01:55:03
  C      Log out  01.01.2018  01:59:03
  </code></pre>
  
  <p>This table is inserted in a pivot table and I've tried to find out how many users are online within a certain timeframe. In our example, at 01:56 there are 2 user online (A and C). In the pivot table I did the following: In "Axis Field" I added the Id and Date and on the "Legend Field" the Status (Login and Logout). I added the data into a line chart and I have 2 lines, one for log in and one for log out. However, I can see the time where a user has logged in/out, but I can not see how many user are online. Any idea how I can fix this? Thanks!</p>
  
  <p>For example these lines represents log in and log out </p>
