有没有办法在SVG容器之外如何将Highcharts工具提示放在鼠标上方？
现在工具提示有时显示在数据上，因为它不适合数据点上方的容器。

大！我找到了一个似乎在jsfiddle中工作的例子：http://jsfiddle.net/vbddw4r0
$(function () {
var chart;
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
min: 0
},
tooltip: {
enabled: true,
backgroundColor: "rgba(255,255,255,0)",
borderWidth: 0,
shadow: false,
useHTML: true,
formatter: function () {
return '<div class="tooltip"><b>' + this.series.name + '</b>' +
'<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '<br/>' + Highcharts.dateFormat('%b %e, %H:%M', this.x) + ': ' + this.y + '</div>';
}
