Colormap legend for 3D panel

[eeyrw]

I can colorize point cloud through settings here:

But no legend of the colormap is on the panel.

Hello @eeyrw thanks for the input. Just to confirm, you mean that you miss like a visual component that shows the color map values on the panel?

something like that?

Exactly. I prefer left one. I tried to generate an image of legend of colormap but the max and min of colorization is set from panel settings rather than receiving from point cloud message. So it is not a practical way to achieve the legend like this. Without legend colorizing point cloud just makes point fancy but no clear semantics especially colormap like rainbow and turbo.
