Instead of category, you should use datetime xAxis type and define x values as timestamps:

series: [{
    ...,
    data: [
        [17227780000, 15],
        [18523780000, 13],
        [19819780000, 14],
        [21115780000, 17],
        [22411780000, 12],
        [23707780000, 12],
        [25003780000, -12],
        [26299780000, -13],
        [27595780000, 21],
        [28891780000, 11]
    ]
}]

or use pointStart and pointInterval properties:

series: [{
    pointStart: 17227780000,
    pointInterval: 1000 * 60 * 60 * 24 * 15, // 15 days
    name: null,
    color: 'red',
    negativeColor: 'blue',
    data: [15, 13, 14, 17, 12, 12, -12, -13, 21, 11]
}]
