does

gruff is pretty nice, but doesn’t do the log scale out of the box. It  
shouldn’t be hard to do the log bit yourself though. There’s also  
scruffy, but I haven’t used that one

this works for me, the basic idea is generate xml on server side and  
use a flash program on the client to build the plot.

There is also some plugins around that do the same … but they work  
with the same flash library and ideas.

gdchart (see [http://raa.ruby-lang.org/project/gdchart](http://raa.ruby-lang.org/project/gdchart)) is quite good  
although no longer actively maintained.

gruff ([http://nubyonrails.com/pages/gruff](http://nubyonrails.com/pages/gruff)) also look promising  
and its website as also an ‘Other graphing software’ section.
