[opendx-users] boxing colormap from Autograyscale

[Michele Cercato]

Hi all
I'm using autograyscale to form an image of 2D data.
The colormap coming from autograyscale is the input for colorbar.
through "Collect" the colorbar is merged with the Autograyscale mapped data
to for the final output image. As I use a white background, I'd like to put
a frame on the edges colorbar. Can anyone suggest the way to do that?
Cheers
Michele
