[Solved]-redraw piechart with Highcharts using JSON data-Highcharts

To update dynamically you have to use setData, like the following.

var json = jQuery.parseJSON(response),
    protocols = json.services.protocols,
    data = [];

for(var i=0; i<protocols.length; i++) {
    var tmp = protocols[i].prot;
    data.push({tmp: protocols[i].byte_len});
}

chart.serie[0].setData(data);
