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!
