[Solved]-HighCharts is only displaying the Title-Highcharts

I think the json data from the url may be not in the right format for the High Charts. Try to include the onError function on the getJSON function and check the error.

Problem is in your date/time. You should multiply your times with 1000

I had wrapped the data series, which were properly in curly brackets, with an outer curly bracket. It should be a square bracket since it's returning an array of objects. Thanks for the help folks. So when you need to send multiple series that have multiple parts (date and time, or a start and end range) to Highcharts through JSON, you want:

[{name:my1stSeries, data:[[1,2],[3,4],...,[m,n]]},{name:my2ndSeries, data:[[5,6],[7,8],...,[o,p]])]
