    series: [{
        name: 'Category I',
        data: [
            [Date.UTC(2014, 5, 14), 20],
            [Date.UTC(2014, 5, 15), 30],
            [Date.UTC(2014, 5, 16), 25],

您可以尝试使用stacking 并在series 中使用stack 进行一些操作，但您的图 TableView 会发生变化。

$(function () {
    $('#container').highcharts({
        chart: {
            type: 'column'
        },
        title: {
            text: 'Stacked bar chart'
        },
        xAxis: {
            type: 'datetime',
        },
        yAxis: {
            min: 0,
            title: {
                text: 'Testing'
            }
        },
        plotOptions : {
           column: {
                stacking: 'normal'
           }
        },
        series: [{
            name: 'Category I',
            data: [
                [Date.UTC(2014, 5, 14), 20],
                [Date.UTC(2014, 5, 15), 30],
                [Date.UTC(2014, 5, 16), 25],
                [Date.UTC(2014, 5, 19), 10],
                [Date.UTC(2014, 5, 20), 15]
            ],
            stack : 0
        }, {
            name: 'Category II',
            data: [
                [Date.UTC(2014, 5, 14), 25],
                //[Date.UTC(2014, 5, 15), 10],
                [Date.UTC(2014, 5, 16), 35],
                [Date.UTC(2014, 5, 19), 25],
                [Date.UTC(2014, 5, 20), 5]
            ],
            stack : 0
        }, {
            name: 'Category III',
            data: [
                [Date.UTC(2014, 5, 14), 10],
                [Date.UTC(2014, 5, 15), 20],
                [Date.UTC(2014, 5, 16), 35],
                //[Date.UTC(2014, 5, 19), 25],
                [Date.UTC(2014, 5, 20), 15]
            ],
            stack : 2
        }]
    });
});
