[chimerax-users] color key

[Roberto Marabini]

Hi,

  Thanks for the information. Finally, I decided to write a small
python script that use"2dlabels" to create a kind of keybar. The
solution is not a generic one but works for me. I attach the output of
the python script to this email since it may be helpful for someone.
