echarts之雷达图实现

图表数据

var valueType = [
  { name: "sales", index: 0, value: 4300, ratio: 20, max: 6500 }, 
  { name: "Administration", index: 1, value: 4300, ratio: 20, max: 16000 }, 
  { name: "Information Techology", index: 2, value: 4300, ratio: 20, max: 30000 }, 
  { name: "Customer Support", index: 3, value: 4300, ratio: 20, max: 38000 }, 
  { name: "Development", index: 4, value: 4300, ratio: 20, max: 52000 }, 
  { name: "Marketing", index: 5, value: 4300, ratio: 20, max: 25000 }
];
var colorList = ['#007DFF', '#FE739D', '#FFA66F', '#8CE130', '#90D5F6'];
var DynamicRich = {};
valueType.map((m,n)=> {
    DynamicRich['a'+n] = {
        align: 'center',
        fontWeight: 'bold',
        fontSize: 16,
        color: colorList[n]
    }
