题目描述

echarts surface 曲面图 option 属性怎么配置；为什么自己写出来的和官网差距这么大； 是数据本身的原因， 还是因为自己什么属性没配置正确

题目来源及自己的思路

网上搜的相关代码看起来都很平滑，感觉像是自己的data没组对，试了几次都没什么大的差异；不知道究竟是什么原因
求大神指点下， 怎么配置才能使曲面看起来平滑一些

你期待的结果是什么？实际看到的错误信息又是什么？

你的代码中的数据组合不对，x y z各自循环 最后得到了很多个点，所以出来的图很奇怪。
我改了下你的代码，z不做循环了，最后想要展现的点就是z的值的个数，然后就可以展示了，是个平滑的曲面。
