Question

我不熟悉Highcharts，所以我可能在这里错过了一些东西。最近，我正在研究面积图，并且能够绘制该图，并且一切都非常完美，但是我有一个要求，我的面积图应该从x开头为0。有什么办法吗？我附上了屏幕截图和小提琴链接。这是小提琴链接：https://jsfiddle.net/shantanugade/9vwxm412/

Highcharts.chart('container', {
chart: {
    type: 'area'

    text: 'US and USSR nuclear stockpiles'

    labels: {
        formatter: function () {
            return this.value; // clean, unformatted number for year
        }
    },
    accessibility: {
        rangeDescription: 'Range: 1940 to 2017.'
    }
},
yAxis: {
    title: {
        text: 'Nuclear weapon states'
    },
    labels: {
        formatter: function () {
            return this.value / 1000 + 'k';
        }

您可以在图像中看到很小的间隙。

Answer 1

您需要减少xAxis.minPadding属性：

    xAxis: {
        minPadding: 0,
        ...
    }

高图。如何从y轴开始绘制面积线图？
