[PyMOL] show color bar with b-factor

[sunyeping <sun...@al...>]

Dear all,
I am trying to map b factor onto a structure by gradually changing color. I use the following command: 
pymol>spectrum b, blue_white_red, byres=1It seems to work. But I don't know how to make pymol show a color bar presenting the range of b factor. Could you help me? Thanks.Yeping Sun
