[Gnuplot-info] Trouble with labels in multiplot

[marcel1 <cemarcel@u.washington.edu>]

Hi users,
I am running gnuplot 4.2 patchlevel 5 on darwin 8.11.1, having a lot of
trouble adding labels to a 4-panel graph using multiplot. I have read the
manual, searched extensively online, still can't solve my problem. I would
like to: 

i) add labels A, B, C and D to the lower left corners of the four graphs in
my multiplot, in line with the y label
ii) annotate certain graphs with a message, like R^2 = 0.4 in the body of
the plots 

While my plots print out fine, I am experiencing behavior that i don't
understand with the labels. I can get labels to appear on all of the plots,
but I also get a "duplicate" label A that creeps in from the bottom of the
4x4 plot area, as I adjust the position of the desired "A" to the top left
graph. I have tried a variety of changes in the code to see where this comes
from to no avail. 

when I comment out labels that appear later in the code and use >show label
I get:
 label 1 "C" at (0.72, -33, 0) left not rotated back  font "arial, 16"
nopoint
 label 3 "A" at (0.72, 28, 0) left not rotated back  font "arial, 16"
nopoint 

which is what I would want. Strangely, when I do this, the figure also
displays an additional "C" and two misplaced "A"s in seemingly random
locations. Could anyone explain why this is happening and how to set the
labels as I would like them?

Many thanks,
Marcel

[Thomas S. <t.s...@fz...>]

labels are plotted each time a 'plot' command is executed, so
you if need one label per plot, define this (and only this) label
just before calling 'plot'. in your case it would be the best to
work with only one label, redefining it for each plot. and the
positioning should be done in axis-range-independent coordinates:

reset
set multiplot
set size 0.3,0.3
#
set origin 0.1,0.1
set label 1 "A" at graph -0.2,-0.2
plot sin(x)
#
set origin 0.5,0.1
set label 1 "B"
plot sin(x)
#
set origin 0.1,0.5
set label 1 "C"
plot sin(x)
#
set origin 0.5,0.5
set label 1 "D"
plot sin(x)
#
unset multiplot

That's almost certainly caused by a misunderstanding of what 'multiplot' 
  and 'set label' actually do.  The key is that a 'set label' command 
affects _all_ plots following it.  Yes, that means the label you set for 
the first plot of your multiplot will also appear in the other three, 
and so on.  Which you may or may not want.  In the case at hand, you 
don't want it, so you should turn off the labels between individual 
plots.  See 'help unset label'.

Actually, it's what you _don't_ want.

Using one label and redefining for each plot worked perfectly.

Thank you!
