Hello Chimera developer,

I am rendering a PDB file colored according to B-factor value by  
"render by attribute" tool. How can I generate a color scale bar  
besides the structure labeling the color scale used?

Hi Yao,
There's no way to do this directly in Chimera now, though I am working on a tool that will make it easy to produce such a key -- but it's not ready yet.  For now you will have to use an external image-processing program such as GIMP or photoshop to add the key.  There is some basic advice for doing this in this message:  http://www.cgl.ucsf.edu/pipermail/chimera-users/2006-July/000878.html
