Echarts y轴数据重复导致tooltip显示文字重复

原因是在同一时间有两条数据，处理方式在tooltip的formatter把数据放到set数组进行去重。

    tooltip: {
      trigger: 'axis',
      formatter: function (params) {
        const a = [];
        const b =[];
        const c =[];
        var res = "
"  + params[0].value[0] +"
";
for (var i = 0; i < params.length; i++) {
if (params[i].data != undefined) {
a.push(params[i].marker);
b.push(params[i].seriesName);
c.push(params[i].value[1]);
}
}
const seriesMakerList = [...new Set(a)];
const seriesNameList = [...new Set(b)];
const seriesValueList = [...new Set(c)];
for (let i = 0; i <3 ; i++) {
res += "
" +seriesMakerList[i]+ seriesNameList[i] + ":" + seriesValueList[i] + "
";
}
return res;
}
},
