I am looking for a sample of Javascript code to visualise pictures in a tooltip of a pie chart from Highcharts.
I would like to see different pictures according to the sectors I am navigating on...
Thanks in advance.

根据文档,tooltip.formatter
是:
... HTML 的一个子集。除非
useHTML
为 true,否则工具提示的 HTML 会被解析并转换为 SVG,因此这不是一个完整的 HTML 渲染器。支持以下标签:<b>
,<strong>
,<i>
,<em>
,<br/>
,<span>
.
Span 可以使用style
属性设置样式,但仅处理与 SVG 共享的与文本相关的 CSS。
所以你应该像这样设置工具提示:
tooltip: {
useHTML: true,
formatter: function () {
return '<b>' + this.point.name + "</b>: " + this.point.percentage + "%<br/>" +
"<img src='" + this.point.img + "'></img>";
}
},
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Favorite Fruits'
},
tooltip: {
useHTML: true,
formatter: function () {
return '<b>' + this.point.name + "</b>: " + this.point.percentage + "%<br/>" +
"<img src='" + this.point.img + "'></img>";
}
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
name: 'Fruits',
colorByPoint: true,
data: [{
name: 'Apple',
y: 50,
img: "https://i.imgur.com/MmK9Xkc.png"
}, {
name: 'Banana',
y: 25,
img: "https://i.imgur.com/0G6GXWf.png"
}, {
name: 'Orange',
y: 15,
img: "https://i.imgur.com/Dv4KoD5.png"
}, {
name: 'Watermelon',
y: 10,
img: "https://i.imgur.com/2LN8PfD.png"
}, ]
}]
});

您可以使用 tootlip 格式化程序和 useHTML,然后返回您定制的内容,包括图像。
