Highcharts & tooltip error

Question

The problem with getting tooltips. You see only tooltip on the first point and the last over.

How to help output tooltip for all points on the graph?

var chart = new Highcharts.Chart(options);

Answer 1

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();
