@shernade Just load this code after loading the highcharts library. No need to implement anything else.

Unfortunatelly chart zooming doesn't works. I use highcharts 3.0.9 (i can update to 4.x) and settings chart: {type: 'scatter', zoomType: 'xy'} and zooming by pinch doesn't work. Without this fix - works. Tested in newest Chrome on Android (multitouch detected)

In v4.x (only tested with 4.1.4 on Android), pinch zooming doesn't work correctly. Fix for 4.x is in the following gist:
