I have a list of arrays as [x,y] for Highcharts. My x-values are timestamps in the format 2013-04-30 00:04:00
.
Here\'s an example of the Highchart options:
yes you can go with UNIX timestamp I mean the timestamp in milliseconds. highcharts accept them as direct integer input for date-time type of x-Axis.
ex: 30/04/2013 00:00:00:000 = 1367260200000
you can pass this value like
data: [[1367260200000, 30],[1367260260000, 32], ....]
Hope this will be of your use.
