关于Echarts的使用方法参考：vue2中echarts的使用_vue2中使用echarts-CSDN博客

实现效果：

代码：

var sysT = {"用采": '#2D9BFF',"营销系统": '#39BFFF',"ERP": '#76C2FF',"财务管控": '#5F57FC',"PMS": '#2D9BFF',"近源层_用采": '#92FFFF',"近源层_营销": '#ACFF96',"近源层_ERP": '#7583FF',"近源层_PMS": '#73C3FF',"近源层_财务管控": '#5477FE',"资产域": '#5F57F9',"客户域": '#7982FE',"财务域": '#4F78FE',"标准区_用采": '#2B9DFF',"标准区_营销系统": '#92FFFF',"标准区_ERP": '#38C0FF',"标准区_财务管控": '#74C3FF',"标准区_PMS": '#AAFF95',"分析层自建宽表": '#73C3FF'
