Highcharts配置 之前已经将Highcharts的大致操作都讲了一遍，现在我来介绍下Highcharts的参数配置。 属性和事件 以下主要参考[参数配置](https://www.runoob.com/highcharts/highcharts-setting-detail.html) chart.events.addSeries：添加数列到图表中。 // // chart.events.click：整个图表的绘图区上所发生的点击事件。 // // chart.events.load：图表加载事件。 // // chart.events.redraw：图表重画事件，当点击图注显示和隐藏绘图时可以触发。 // // chart.events.selection：当图表曲线可选择放大时，当选择图表操作时，可以触发该事件。 // // chart.height：所绘制图表的高度值。 // // chart.inverted：图表中的x，y轴对换。 // // chart.polar：是否为极性图表。 // // chart.reflow：当窗口大小改变时，图表宽度自适应窗口大小改变。 // // chart.renderTo：图表加载的位置，是页面上的一个DOM对象。 // // chart.showAxes：在空白图表中，是否显示坐标轴。 // // chart.type

Is there any way to automatically calculate the axis labels' step size in Highcharts ?

由 ╄→尐↘猪︶ㄣ 提交于 2020-01-24 22:11:47
问题 I have 1000~ data labels on the xAxis and finding a way to automatically calculate the step based on the number of data labels and size of the charts. Based on the documentation , if I do not set the step property of xAxis.labels , it will be calculated automatically, But in my case it is not. Current output: Expected output: Currenlty the labels look as shown in the image. I'd expect the labels to drop automatically and do not show the ellipses. Any help would be much appreciated. Thanks. -I

问题 Is there any way to make completely custom tooltips in Highcharts diagrams? Not just with different data, or with coloured border, but to make it look different (for example, like a bubble with picture in it). 回答1: Try this: .... tooltip: { useHTML: true, formatter: function() { return 'here the html code'; } }, 回答2: Using the options/api you can only configure such things as border properties and colors (see tooltip options).
