漏刻有时数据可视化Echarts组件开发(46)散点图颜色判断

series组件

series: [
        {
      name: 'Top 5',
      type: 'scatter',
      coordinateSystem: 'bmap',
      data: convertData(
        data
          .sort(function (a, b) {
            return b.value - a.value;
          })
          .slice(0, 6)
      ),
      symbolSize: 20,
      encode: {
        value: 2
      },
      showEffectOn: 'render',
      rippleEffect: {
        brushType: 'stroke'
      },
      label: {
        formatter: '{b}',
        position: 'right',
        show: true
      },
      itemStyle: {
        color:function(d){
          var a= d.data.value[2];
          console.log(d.data.value[2]);
          if(a % 2 == 0){
            return 'red';
          }else{
            return 'green';
          }
        },
        shadowBlur: 10,
        shadowColor: '#333'
      },
      emphasis: {
        scale: true
      },
      zlevel: 1
    }
  ]

核心代码

itemStyle: {
        color:function(d){
          var a= d.data.value[2];
          console.log(d.data.value[2]);
          if(a % 2 == 0){
            return 'red';
          }else{
            return 'green';
          }
        },
