Take a look at 'xgraph' in the contrib distribution.
It has linear/log options for x and y axes, zoom with the mouse
and hardcopy output.

That is exactly the name of the existing  program.

It is a standalone program that (in fact) uses only Xlib (no toolkits)
and is very nice.
It is available via anonymous ftp from expo.lcs.mit.edu (18.30.0.212) in
contrib/xgraph-11.tar.Z

Be sure to set binary mode when copying it.
