any **sample code** to help us figure it out?

> the node information cannot be obtained What is the "node information" ? Do you have sample code? The globe itself does not respond to clicks, it's a coordinate system...

There is no _markPoint_ for [surface](https://echarts.apache.org/en/option-gl.html#series-surface.type). But one can position text anywhere with [scatter3D](https://echarts.apache.org/en/option-gl.html#series-scatter3D.label).

The bug is related to _linesGL_. When series type is replaced with **"lines"**, there is no error.

@Siwuji, _textStyle.backgroundColor_ is undocumented, but it works.

@Ovilia mentioned custom series. Contour plots are doable with [custom.polygon](https://echarts.apache.org/en/option.html#series-custom.renderItem.return_polygon), see #18344.

As @plainheart said - good candidate for an extension, but not for an integral part of ECharts. There are two separate questions here: 1) how to **extract** contours and 2)...
