绘制surface的问题 #319

Open kickasss opened 4 years ago

kickasss commented 4 years ago

请问使用echarts4.5.0和echarts-gl1.1.2绘制surface时曲面的两端会自动连接起来是什么原因？我用的data是grid 0001 0002

oxydaemon commented 4 years ago

I had similar issue with echarts 4.7, echarts-gl 1.1.2

This appears to be caused by software thinking "first" and "last" data is a surface, so you see it draw a line between them I solved by sorting my Z data input tuples

Try sorting your Z data - I sorted [(X,Y,Z)] by X -> Y -> Z and showed up correctly

Also if you don't include any code / sample data in your issue its hard for them to troubleshoot :-)

yes,i also meet with this problem.after sort x,y,z,and x must appear twice more ,it can be handled.

请问x出现两次是什么意思，我现在是每组十个数据，x轴的值从小到大，y轴的值不变，z轴的值不定，这样排序的

yunnuoyang commented 3 years ago

意思就是x轴数据你从小到大假如是：1，2，3，4，这样绘制不出来的，不符合成图形的条件吧，你的数据应该是1，2，3，4，1这种，至少x有重复的数据。
