实现效果： 关键代码 xAxis: [{type: 'category',axisTick:{show: false},axisLine:{show: false},axisLabel:{align:'center',},data: ['9-w2', '9-w3', '343','9-w2', '9-w3', '343']},{type: 'category',name: '排比变化',nameTextStyle: {verticalAlign: "left",padding:[24,0,0,0]},nameLocation: 'start',position: 'bottom',offset: 18,axisPointer: {type: 'none'},axisTick:{show: false},axisLine:{show: false},axisLabel: {interval:0,align: 'center'},splitLine: { // 新增代码，设置分隔线样式show: false,lineStyle: {type: 'dashed',color: '#999',width: 1}},data: ['9-w23', '9-ww3', '343','9-w2', '9-w3', '343']}]
