堆积列不会在x轴上格式化到目前为止的时间戳

问题描述 投票：0回答：1

我创建了一个带有高图表的简单堆积柱形图。我在这里处理的数据相当于高图表示例：https://www.highcharts.com/demo/column-stacked唯一的区别是我在x轴上有unix时间戳问题：我的时间戳没有正确转换为日期格式：％Y-％m-％d这里是jsfiddle ：https://jsfiddle.net/marialaustsen/e8d5snzt/

您必须使系列数据结构适应Highcharts所需的格式。例如，您可以使用数组：data: [[0, 6], [1, 2]]，其中第一个值表示x，第二个值表示图表上的y：

所以，在你的例子中：

var timestamps = [-315622800000, -284000400000, ...];

...

var chart = new Highcharts.Chart({

    ...,

    series: [{
        name: 'Noneprobability',
        data: (function() {
            var data = [1.5, 1.5, ...];

            data = data.map(function(el, i) {
                return [timestamps[i], el]
            });

            return data
        })()
    }, ...]
})
