echart可以动态修改每个数据的label 代码如下：
data: type == '01' ? this.yList[0].data.map((item, index) => {
console.log(item, '11111');
this.yList[1].data.map((res, it) => {
if (index === it) {
if (Number(item) < Number(res)) {
judgeFlag = true;
}
}
console.log(res);
});
console.log('zuihou');
return {
value: item,
label: {
show: true,
position: judgeFlag ? 'bottom' : 'top',
distance: 2,
offset: judgeFlag ? [0, -8] : [0, 8],
color: '#181716',
fontSize: 30,
// backgroundColor: '#fff',
backgroundColor: { image: judgeFlag ? this.topArrow : this.bottomArrow },
borderColor: 'rgba(0,0,0,0.31)',
// shadowColor: 'rgba(0,0,0,0.31)',
fontFamily: 'Bebas',
// shadowBlur: 6,
padding: judgeFlag ? [12, 8, 6, 8] : [4, 8, 10, 8],
lineHeight: 40,
borderRadius: 4,
formatter: (params) => this.numberConvert(params.value)
},
};
// eslint-disable-next-line no-loop-func
}) : this.yList[1].data.map(item => {
