推荐答案

您需要配置按钮如果您想要范围选择器

You need to configure buttons if you want the range selector

xAxis: {
    events: {
        afterSetExtremes: function(e) {
            var minDistance = 36 * 30 * 24 * 3600 * 1000; //36 months time
            var xaxis = this;
            if ((e.max - e.min) < minDistance) {
                var min = e.max - minDistance;
                var max = e.max;
                window.setTimeout(function() {
                    xaxis.setExtremes(min, max);
                }, 1);
            }
        }
    }
}
rangeSelector: {
    selected : 1,
    buttons: [{
        type: 'month',
        count: 36,
        text: '36m'
    }, {
        type: 'month',
        count: 42,
        text: '42m'
    }, {
        type: 'month',
        count: 48,
        text: '48m'
    }, {
        type: 'month',
        count: 54,
        text: '54m'
    }, {
        type: 'all',
        text: 'All'
    }]
}
