title: Set the number formatting in general for a Highcharts chart?
body: <p>I've been looking all over, and testing one million things now. I just can't get it to work. I want the numbers to show up as "99 999" instead of "99,999".</p>
  
  <p>Yes, I eventually found "thousandsSep", but it seems to be ignored completely. All my numbers show up as "99,999" even when I have "lang: { thousandsSep: ' ' }" and whatnot.</p>
  
  <p>Please help.</p>
