jquery - Highcharts 刻度间隔为5天

我似乎无法弄清楚如何正确设置刻度间隔。
需要在X轴上有5天时差的价格变动。我想显示x轴，例如“ 3月1日，3月5日，3月10日，3月15日”等

Fiddle Example

下面给出的Java脚本

            <script type="text/javascript">
            $(function () {
            $('#container').highcharts({
                chart: {
                    zoomType: 'x'
                },
                title: {
                    text: 'USD to EUR exchange rate from 2006 through 2008'
                },
                subtitle: {
                    text: document.ontouchstart === undefined ?
                            'Click and drag in the plot area to zoom in' :
                            'Pinch the chart to zoom in'
                },
                xAxis: {

最佳答案

您可以随时使用tickPositioner，演示：http://jsfiddle.net/96x5dz5c/2/

xAxis: {
    type: 'datetime',
    tickInterval:24 * 3600 * 1000 * 5,
    tickPositioner: function(min, max){
         var interval = this.options.tickInterval,
             ticks = [],
             count = 0;

        while(min < max) {
            ticks.push(min);
            min += interval;
            count ++;
        }

        ticks.info = {
            unitName: 'day',
            count: 5,
            higherRanks: {},
            totalRange: interval * count
        }


        return ticks;
    }
},
