[Solved]-Highcharts & tooltip error-Highcharts

Highcharts expects the data to be presorted ascending on the X values.

   someData = [
        [1365895320000, 26],
        [1365895020000, 26.0625],
        [1365894720000, 26.0625],
        [1365894420000, 26.0625],
        [1365894120000, 26.125],
        [1365893820000, 26.125]            
    ];

    someData.sort();
