Question

我对Highchart有疑问。

我使用xrange图表。

您可以在图片中看到系列之间的空白

未缩放的图表

当我缩放图表时，如您在图片中看到的，空白空间消失了，它出现了一系列。如何使其始终显示系列？我在做什么错了？

放大的图表

我的代码：

var chart = Highcharts.chart('container', {
    chart: {
    	height: 240,
      zoomType: 'x',

您有什么想法吗？

Answer 1

您可以使用minPointLength选项设置列的最小宽度：

series: [{
    type: 'xrange',
    minPointLength: 2,
    ...
}]

高图不显示小系列
