//定义两个上下箭头的矢量路径 var up = 'path://M286.031,265l-16.025,3L300,223l29.994,45-16.041-3-13.961,69Z'; var down = 'path://M216.969,292l16.025-3L203,334l-29.994-45,16.041,3,13.961-69Z'
series: [ { "name": "", type: 'pictorialBar', symbol: function(data,params){ if(data2[params.dataIndex]>0){ return up }else{ return down } }, symbolSize: [20, 30], symbolOffset: [0, -40], color:'orange', symbolPosition: 'end', label: { show: true, position: "top", formatter: function(params){ return data2[params.dataIndex] }, fontSize: 30, fontWeight: 'bold', color: '#34DCFF' }, data: data1 }, { name: '直接访问', type: 'bar', barWidth: '40%', data: data1 } ]
重点代码：
symbol: function(data,params){ if(data2[params.dataIndex]>0){ return up }else{ return down } }
DONE!
