title: highcharts bubble chart legend with unique numbers
body: <p>Please have a look at <a href="https://imgur.com/nhQrNKy" rel="nofollow noreferrer">this bubble-chart picture</a>.</p>
  
  <p>You see I have 3 series <code>bundle</code>, <code>system</code> and <code>product</code>.
  Within these series a number makes them unique.
  Each bubble has a "name" which is very long unfortunately.</p>
  
  <p>Now I had the Idea, that I put that into the legend not into the bubble itself.</p>
  
  <p>Is this possible? </p>
