legends position multiplot gnuplot

Question

I am using Windows 10 and Gnuplot 5.0. I have a script to plot several graphs simultaneously:

GNUTERM = "wxt"
set terminal wxt
set termoption enhanced
set encoding iso_8859_1
set multiplot layout 1,3
set xtics out
set ytics out
set xtics nomirror
set ytics nomirror
set xzeroaxis linetype 2 linewidth 1.5
show xzeroaxis
# Graph1
set key center right
set xrange [3.3:9.0]
set yrange [-0.1:1.10]
set title "Title 1"
set xlabel "x"
set ylabel "y"
plot \
"results_1.dat" u 1:2:4 title "exp." with e pointtype 9 pointsize 0.5 linecolor rgb "red" , \
"results_1.dat" u 1:3 title "fit." with line linecolor rgb "black" linewidth 2 dashtype 2 smooth bezier
# Graph2
set xrange [3.3:9.0]
set yrange [-0.1:1.10]
set key top right
set title "Title 2"
set xlabel "x"
set ylabel "y"
plot \
"results_2.dat" u 1:2:4 title "exp." with e pointtype 9 pointsize 0.5 linecolor rgb "blue", \
"results_2.dat" u 1:3 title "fit." with line linecolor rgb "black" linewidth 2 dashtype 2 smooth bezier
# Graph3
set xrange [3.3:9.0]
set yrange [-0.1:1.10]
set key outside vertical top right
set title "Title 3"
set xlabel "x"
set ylabel "y
plot \
"results_3.dat" u 1:2:4 title "exp." with e pointtype 9 linecolor rgb "red", \
"results_3.dat" u 1:3 title "fit." with line linecolor rgb "black" linewidth 2 dashtype 2 smooth bezier
unset multiplot
pause 3
reread

However, instead of getting the legend outside only for the graph 3, all legends are shown outside the graphs (see attached image)

I want legends 1 and 2 inside the graphs and legend 3 outside. What's wrong in my script?

Any help is appreciated.

Give us your data files! But yo may try set key inside yourself first. — vaettchen

It's hard to say without being able to run your script, but if I had to guess I'd say that you request the legend to be outside for graph 3, and when you reread the script you don't put it back inside. Try something like

set key inside center top

for the first graph (or add a reset statement to the beginning of your script).
