I apologize my fuzzy question. I just dislike the look of (e7.1), and
using ytickformat with function seems very good idea. I appreciate
Vidar's function and Fanning's comments.
Please share the expenses of dinner in Oslo!

This whole discusssion reminds me of my favorite
pet peeve about technical support engineers. So many
of them (like I did) answer the *question* rather than
(like Stein Vidar did) solve the *problem*. And I suspect
many of them do it for the same reason I did: there are
not enough hours in the day to do everything that
needs doing. Answering questions is quite a bit easier
than solving problems. :-)
But the number one rule of technical support, it seems
to me, is that the question is almost always indicative
of confusion, not clear thinking. If most bright people
think clearly about a problem, they can usually solve
it on their own. Thus, just answering the question is
often not all that helpful. The best support engineers,
like Stein Vidar, anticipate the problem behind the question
and work to solve that. Often the problem is nothing more
than fuzzy (or incomplete) thinking on the part of the user.
In any case, I'll be happy to spring for dinner the next
time I'm in Oslo because no matter which question you answer--
the one asked or the one anticipated--I almost always
learn something worth knowing. :-)
Cheers,
David

Dave,
I just cancelled a previous post where I had written:

Now that I've re-read the original question, I see that Shimizu
did mention ytickformat:
> ...I don't like to use following style.
>> plot, [0, 1e4], ytickformat = '(e7.1)'
However, I think what he meant was he didn't like the look of
using ytickformat='(e7.1)', not that he wouldn't use ytickformat
at all.... how about a draw?
Regards,
Stein Vidar

Sure, it is easily possible with a function. But the
man said he didn't what to use the keyword. What can
I say? I stand by my statement and I accept the bet.
Dinner next time I'm in Oslo? :-)

Oh - wanna bet? :-)
Using the xtickformat to name a formatting function, this
can definitely be done. Try the following:
FUNCTION ytf,axis,index,n
IF n EQ 0 THEN return,'0' ;; Special case
ex = string(n,'(e7.0)')
pt = strpos(ex,'.')
first = strmid(ex,pt-1,1)
sgn = strmid(ex,pt+2,1)
exp = strmid(ex,pt+3,100)
;; Shave off leading zero in exponent
IF strmid(exp,0,1) EQ '0' THEN exp = strmid(exp,1,100)
IF sgn EQ '-' THEN return,first+'x10!A'+sgn+exp $
ELSE return,first+'x10!A'+exp
END
and then do
plot, [0, 1e5], ytickformat = 'ytf'
It appears that the "native" IDL tickmarks use a special
symbol for "times" - not simply an "x".... but that's
just about the only difference I can see!

Stein Vidar
