相信大家在工作中，经常会用到echarts，今天我说下我在工作中浪费时间较长的坑
先来看看我的终极需要实现的图吧：
相信以上效果对于常用的小伙伴来说并不困难，
在此我只说option的配置，关于数据，就不在此赘述了，毕竟大家的情况都不太相同，处理就起来也不太一样。
option : {

我想说的是关于series的设置，一定要把，横坐标或者是纵坐标对应好，不然的话就很容易出现如下问题
‘type is undefined‘ 我的是报这个错喽，具体你的是什么错，我就不知道了，但是如果你的数据没有问题，图表不出来的话，就是 gridIndex ，yAxisIndex， xAxisIndex 没有对应好
