Im plotting one picture with 4 different graphs using gnuplot. Labels for their x and y axes have the same meaning. If Im plotting it like this:

```
set multiplot layout 2,2 rowsfirst
set xlabel "x"
set ylabel "y"
set title offset -3,-3
set xrange [20:70]
set yrange [0:15000]
set title "Plot 1"
plot 'data5.list' u 2:1 w lp pt 7 lt 7 lc rgb 'red' notitle
set xrange [20:70]
set yrange [0:15000]
set title "Plot 2"
plot 'data5.list' u 2:1 w lp pt 7 lt 7 lc rgb 'red' notitle
set xrange [20:70]
set yrange [0:15000]
set title "Plot 3"
plot 'data5.list' u 2:1 w lp pt 7 lt 7 lc rgb 'red' notitle
set xrange [20:70]
set yrange [0:15000]
set title "Plot 4"
plot 'data5.list' u 2:1 w lp pt 7 lt 7 lc rgb 'red' notitle
unset multiplot
```

I have all four graphs and their labels, but I want to achieve to have one label for all four of them, as in this example .

I tried with unset label for other 3 plots, but I get labels only on first of them, while the other do not have labels at all.

# Best How To :

Instead of using `xlabel`

and `ylabel`

, you may want to go with `set label`

. For example,

```
#!/usr/local/bin/gnuplot
datafile='tmp.dat' # file to plot
set xlabel " " # no x-label
set ylabel " " # no y-label
# assuming all plots have same x and y range
set xrange [-2:2]
set yrange [-4:4]
# same setting for all graph titles
set title offset -3,-3
# puts x-label and y-label manually
set label 1 'x axis' at screen 0.49,0.02
set label 2 'y axis' at screen 0.01,0.5 rotate by 90
# now the graphs: notice that rowsfirst is given by default
set multiplot layout 2,2
do for [i=1:4]{
set title 'plot '.i
plot datafile u 2:1 w lp pt 7 lt 7 lc rgb 'red' notitle
unset label 1
unset label 2
}
unset multiplot
reset
```

If all plots can be done by the same line-syntax, then I recommend to use a do-loop (as in the example above) instead of copying it each time.

Notice that `gnuplot`

will put the labels 1 and 2 each time a graph is plotted. That is why I put `unset label 1`

and `unset label 2`

inside the do-loop, so the labels are placed just in the first iteration.

If you want to have something similar to the example you provided, then I recommend to use this script (explained through the comments):

```
#!/usr/local/bin/gnuplot
datafile='tmp.dat' # file to plot
# parameters to configure margins of each graph
x0=0.1 # left margin all graphs
y0=0.99 # top margin all graphs
lengthx=0.4 # horizonal length of each graph
lengthy=0.4 # vertical length of each graph
spacex=0.04 # horizontal space between each graph
spacey=0.04 # vertical space between each graph
# This is a macro: configure the top, right, left, and bottom margins of each graph.
# It will depend on the value of i and j.
set macro
i=0; j=0;
SETMARGINS = "set tmargin at screen (y0-i*(lengthy+spacey));\
set bmargin at screen (y0-i*(lengthy+spacey)-lengthy);\
set lmargin at screen (x0+j*(lengthx+spacex));\
set rmargin at screen (x0+j*(lengthx+spacex)+lengthx)"
# Assuming all plots have the same x and y range. If not, set it in each plot below
set xrange [-1.5:1.5]
set yrange [-4:4]
# general setting for plot titles
set title offset -3,-3
# don't worry about the axis labels for now
unset xlabel
unset ylabel
