[Fixed]-Change color of Multibar chart in Django

Colors can be set per point.

series: [{
  data: [{y: 1, color: '#ff0072'}, 
         ...

Example: http://jsfiddle.net/sbphxhfs/

Other option is to set negativeColor and threshold

series: [{
  negativeColor: 'red',
  threshold: 3,
  ...

Example: http://jsfiddle.net/sbphxhfs/1/

Colors can be also set for series (using color setting), or whole chart (using colors array).
