Handling unix timestamp with highcharts

Question

jsfiddle: http://jsfiddle.net/RjPRd/

Times & Labels are displayed incorrectly.

I think the timestamp should be multiplied by 1000 for Ja

Answer 1

An easy way to work with timestamp (milliseconds) in Highcharts is use the formatter. So first receive your time values as unix timestamp and then set one of the features below in the chart:

Using in xAxis labels:

xAxis:[{
  labels:{
     formatter:function(){
         return Highcharts.dateFormat('%Y %M %d',this.value);
     }
  }
}]

Using in tooltip:

tooltip: {
    readerFormat: {
        formatter: function(){
         return Highcharts.dateFormat('%Y %M %d',this.value);
     }
  },
    pointFormat: '{point.y} ms',
    shared: true
},
