plotly.js
1

Only title is shown https://jsfiddle.net/rdmd9mab/ yet I want to see the legend and have axis named. How to do such thing for 3d plots?

Axis properties have to be wrapped inside a scene object in 3D graphs. See patched version:Edit fiddle - JSFiddle - Code Playground

Not all trace types can have associated legend items. At the moment, surface and mesh3d don’t support legend items unfortunately.

Any updates on this: Not all trace types can have associated legend items. At the moment, surface and mesh3d don’t support legend items unfortunately.

Is it still unsupported?

This would be possible with next minor version.
