Yes, I agree. What I was missing, and what Richard first mentioned,
was the log10 part. I was having trouble figuring how to round it up
to a "nice" value, and just didn't think of changing the axis system
(interesting how fortran programmers have a pragmatic view on these
problems).
Well, just would like to thank everyone for their (very!) useful
suggestions, I understood the idea how to do it. Now all I have to do
it is to get it to work without errors :-)
