formatter一下，保留一位小数能解决echarts饼图的
相同数字不同百分比的情况，目前采取的是这种解决方式；如有更好的方法，请大佬告知。参数：option = {
title: {
text: "某站点用户访问来源",
subtext: "纯属虚构",
left: "center"
},
tooltip: {
trigger: "item",
// formatter:"{a} <br/>{b} : {c} ({d}%)"
formatter: function(data) {
const { name, value } = data.data;
const { seriesName, percent } = data;
return `${seriesName}<br/>${name}: ${value} (${percent.toFixed(1)}%)`;
}
},
legend: {
orient: "vertical",
left: "left"
},
series: [
{
name: "访问来源",
type: "pie",
radius: "50%",
data: [
{ value: 1048, name: "搜索引擎" },
{ value: 735, name: "直接访问" },
{ value: 580, name: "邮件营销" },
{ value: 300, name: "联盟广告" },
{ value: 300, name: "视频广告" }
],
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: "rgba(0, 0, 0, 0.5)"
}
}
}
]
};
