更改Highcharts中特定数据点的工具提示的背景色 [英] Changing backgroundcolor of tooltip for a specific data point in Highcharts
问题描述
我有一个Highcharts折线图并启用了工具提示，但是，我只想更改图表上单个数据点的工具提示的背景颜色.
有可能这样做吗?
到目前为止我有什么
tooltip: {
formatter: function () {
return this.y;
},
backgroundColor: '#68BD49',
borderColor: '#000000',
borderWidth: '1'
},
I have a Highcharts line chart and have tooltips enabled, however, I would like to change the background color of tooltip for just a single data point on the chart.
Is it possible to do so?
What I have so far
tooltip: {
formatter: function () {
return this.y;
},
backgroundColor: '#68BD49',
borderColor: '#000000',
borderWidth: '1'
},
推荐答案
是的，可以使用HTML选项并定义自定义参数.显然，您可以使用CSS样式/类禁用填充/边距，但是以最简单的方式，您可以通过以下方式实现此目的:
Yes it is possible, by using HTML option and define custom parameters. Obviously you can use CSS styles / classes disable padding/margins, but in the simplest way you can achive this in this way:
tooltip: {
useHTML:true,
formatter: function() {
console.log(this);
if(this.point.customBck)
return '<div style="background-color:red;">The value for <b>'+ this.x + '</b> is <b>'+ this.y +'</b></div>';
else
return '<div>The value for <b>'+ this.x + '</b> is <b>'+ this.y +'</b></div>';
}
},
