【问题描述】：
我正在使用 highchart 活动量表。但它的工具提示不会显示在悬停位置。它总是显示在中心。我想在悬停系列上显示工具提示。
这是 js fiddle 悬停在任何系列上。
// Uncomment to style it like Apple Watch
/*
if (!Highcharts.theme) {
Highcharts.setOptions({
chart: {
backgroundColor: 'black'
},
colors: ['#F62366', '#9DFF02', '#0CCDD6'],
title: {
style: {
color: 'silver'
}
},
tooltip: {
style: {
color: 'silver'
}
}
});
}
// */
/**
* In the chart render event, add icons on top of the circular shapes
