title: How to track number of events per unique user on Google Analytics
body: <p>We have an application that tracks the event where a user marks a 'post' as a favorite. In Google Analytics, I can see how many times the favorite-event has been triggered, and I can find out how many unique users have triggered it. Let's say 2000 favorite-events were triggered, and 1000 unique users triggered them. That would mean an average of 2 favorites per user.</p>
  
  <p>I want to track/see how many favorite-events were actually triggered by the unique users, and group them by the number.
  Let's say that 2 of the users have triggered 50 favorite-events each, and the rest has 1 or 2 favorites.</p>
  
  <p>I need a list to see those numbers, for example like this:</p>
  
  <pre><code>[2 users]    [favorited] [50 times]
  [1000 users] [favorited] [1 time]
  </code></pre>
  
  <p>Is there a way to achieve this without having to use custom variables and/or dimensions?</p>
