堆叠列未在 x 轴上格式化时间戳到日期

Stacked column does not format timestamp to date on x axis

我用高图创建了一个简单的堆叠柱形图。我在这里处理了相当于高图表示例的数据: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 这是jsfiddle: https://jsfiddle.net/marialaustsen/e8d5snzt/

您必须调整您的系列数据结构以适应 Highcharts 要求的格式。例如,您可以使用数组:data: [[0, 6], [1, 2]],其中第一个值表示图表上的 x,第二个值表示 y

因此,在您的示例中:

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
        })()
    }, ...]
})
