set autoscale fix; set logscale y2

[Petr M. <mi...@ph...>]

There are wrong tics on the y2 axis if the following is set:
	set autoscale fix; set logscale y2
The problem was discovered in one of graphs produced by Octave.
The problem is in gnuplot since version 4.0.


reset
set ytics
set logscale y
set yrange [1:100]

set y2tics
set logscale y2
set y2range [1:100]

plot 1+x*x

pause -1

set autoscale fix
replot


I don't see any reason why AUTOSCALE_FIXMIN causes double-exponentiation of 
the y2 axis. Any idea?

***

Observation by John W. Eaton:

When I execute the following commands in gnuplot, the y2 tick marks appear
to be linearly spaced and the y2 tick labels do not appear:

  set logscale y2
  plot sin (x) axes x1y1, exp (x) axes x1y2

but after executing

  set logscale y
  replot

they do appear, but then the y1 axis is also log scaled.  Is is possible to
set them independently?
