#2808 — Re: axis range wrong in multiplot - multiplot.gp (1/1)

This seems to be still broken in 4.6

Sam-OConnors-MacBook-Pro-84:dump sam$ /opt/local/bin/gnuplot --version
gnuplot 4.6 patchlevel 4

(using png output)

I don't think that is correct.  The problem described earlier in 
this thread was fixed in 2012 and therefore the fix should have first
appeared in version 4.6.1 (Sep 2012).
Maybe you are seeing a different problem?

On my machine, gnuplot --version says "gnuplot 4.6 patchlevel 4".
Does that mean its 4.6.4?

The following plot results in both y-axes having 10 at the bottom and 0 at the top:

set terminal png;
set multiplot layout 2,1;
set yrange [10:0]; plot (5);
set yrange [0:10]; plot (5);

Adding the "noreverse" option to the second yrange fixes the problem:

set terminal png;
set multiplot layout 2,1;
set yrange [10:0]; plot (5);
set yrange [0:10] noreverse; plot (5);

Ah, I see.  That is not exactly the problem I thought you
meant.  Yes, the "reverse/noreverse" option was (IMHO) a
total mess up to and including version 4.6   It was reworked
for version 5 and now only affects autoscaling.  See the
release notes and User Manual section on "Changes in version 5".
The nutshell summary:

%%%
The reverse keyword of the set [axis]range command affects only autoscaling.
It does not invert or otherwise alter the meaning of a command such as
set xrange [0:1]. If you want to reverse the direction of the x axis in
such a case, say instead set xrange [1:0].
