Fix #446, #447 issues. 1) Only refresh the events bound by echart when the event changes. 2) If the style or classname changes, it's more reasonable to refresh the data after performing charts.resize first.

1. 仅事件变化时只刷新echart绑定的事件；
2. 如果style或者className变化，先进行echarts.resize再刷新数据更合理

另外，求帮忙加一个单侧，针对这个修改。

Pretty useful @iitodo 🚀. I've linked your repo in my project, and it works like charm when managing events.
