ECharts实现折现图的拐点为空心圆圈

效果：

let option = {tooltip: {trigger: 'axis',axisPointer: {type: 'cross',crossStyle: {color: '#999'}},formatter: function (params) {return '';}},grid: {left: 10,right: 40,bottom: 10,top: 45,containLabel: true},legend: {top: 30,right: 40,itemWidth: 10,itemHeight: 10,textStyle: {color: '#aaa'},data: [{name: '当前',icon: ''},{name: '同比',icon: ''},{name: '日均',icon: 'line'},]},xAxis: [{type: 'category',data: ['2022-10-25'],axisPointer: {type: 'shadow'},axisLabel: {color: '#838383',fontSize: 12,interval: 0,// rotate: 35},axisTick: { show: false },axisLine: {show: true,lineStyle: {color: '#eee',}}}],yAxis: [{type: 'value',axisLine: {show: true,lineStyle: {color: 'transparent'}},axisTick: {show: false},splitLine: {show: false},axisLabel: {formatter: '{value}%',color: '#B2BCCB',fontSize: 10},position: 'left',splitLine: {show: true,lineStyle: {color: '#F5F5F6',type: 'dashed'//虚线}}}],series: [{name: '当前',type: 'line',data: [{symbol: 'emptyCircle',symbolSize: 8,value: 0}],itemStyle: {color: '#8ED53B',deccal: {symbol: 'rect',}},},{name: '同比',type: 'line',data:  [{symbol: 'emptyCircle',symbolSize: 8,value: 0}],itemStyle: {color: '#438AFE'},},{name: '日均',type: 'line',data:  [{symbol: 'emptyCircle',symbolSize: 8,value: 0}],itemStyle: {color: '#D0D5DB',opacity: 0,},lineStyle: {type: 'dashed'}},]};

在option-》series-》data-》symbol设置为emptyCircle
