Hi,

I have showed the electrostatic potential map around a molecule using surface of electron density.  
Then, I want to show the color bar showing how much electrostatic potential each color shows.

Is there any way to do so?

Thank you very much

Kinoshita

At one point, there was an overlay for this, but I don’t see it in the development version. I’ll look into it for version 1.3
