[hobbit] Clarification: Change graphing on Trends link

[David Gilmore]

Ralph,

I gave your suggestion a shot today, and just when I think I am making
progress learning Linux, I get slapped in the face.  I found the
hobbitgraph.c and made the changes as you outlined below.  I then went to
the parent directory (hobbit-4.1.2p1) and ran make, but it errored out with
error:2.  I checked the mod date on the hobbitgraph.cgi file and it was
still set to the date that I originally compiled the program.  I am running
Hobbit on FC4.  Any suggestions?

Thanks,

Dave
