title: highcharts subtitle formatting
body: <p>I need to format  highcharts title/subtitle,  so change the color of some words and make some words bold. There seems to be no way to do this using the 'standard'parameters. The line of text is coming from a php variable.
  I've tried putting html formatting in the text but that has no effect.</p>
  
  <p>My skills are mostly in PHP and not java so if someone could point me to a piece of code i'd be very gratefull.</p>
