Ok, the option is to add the color bar through the ISL:
http://www.unidata.ucar.edu/software/idv/docs/userguide/isl/ImagesAndMovies.html

looking for "Add a color bar to an image".

It is my first time seeing this warning, I think it is something related to 
your openGL setting. No need
to worry.

When the offscreen is set to true, the user interface will not be generated and 
will not be shown in your result. 
This is the design, not a bug.

Point cloud display uses one of the variable, if you don't want it to be 
altitude, you 
can change it in the display control.

By the way, you may want to change the background of the display to white or 
something lighter.
