Is this plot typical of gnuplot? - gnuplot

Question

I have a look at https://stats.stackexchange.com/tags/data-visualization/info and it seems to me that maybe I can find an answer here... or maybe it is off-topic here too.
Is this plot typical of gnuplot?

Answer 1

It's not the default look of gnuplot.
But gnuplot is quite customizable, and the looks depend on the capability of the output device (terminal) used and the libraries it was built with.
It is not uncommon to have your own ~/.gnuplot or a site-wide /usr/local/share/gnuplot/<version>/gnuplotrc.
From the built-in help:
When gnuplot is run, it first looks for a system-wide initialization file
gnuplotrc. The location of this file is determined when the program is built
and is reported by show loadpath. The program then looks in the user's HOME
directory for a file called .gnuplot on Unix-like systems or GNUPLOT.INI on
other systems. (OS/2 will look for it in the directory named in
the environment variable GNUPLOT; Windows will use APPDATA).
Unless you are student that has to follow your institution's style guide, I would encourage you to develop your own style(s) based on the examples you can find online and your needs.
The information and examples available on gnuplotting.org is very valuable for that purpose.

As #Roland Smith said, gnuplot is quite customizable.
To help you see how customizable it is, see below a complete example which reproduces wanted plot.
reset
set encoding utf8
# ***** TERMINAL SETTINGS *****
set terminal wxt size 800,450 font "Consolas"
# ***** GENERAL SETTINGS *****
# tics, key, and border
set tics nomirror scale 1.5
unset key
set border 7
# linestyles
set style line 1 lc "black"
set style line 2 lc "red"
# margins
set lmargin screen 0.100
set rmargin screen 0.900
set bmargin screen 0.135
# xlabel, xrange, and (m)xtics
set xlabel "Time [sec]"
set xrange [0:2.2]
set xtics 0.2 tc ls 1
set mxtics 4
# ***** CREATING SOME DATA TO PLOT *****

# Storing on datablock
# First one
set table $FlowData
plot f(x, 80.0, 0.25, 0.15)
unset table
# Second one
set table $PressureData
plot f(x, 35.0, 0.75, 0.20)
unset table
# ***** THE PLOTS *****

set multiplot
# ***** FIRST PLOT SETTINGS *****
set ylabel "Flow [l/min]"
set yrange [-10:120]
set mytics 4
# Fist plot itself
plot $FlowData axes x1y1 w l ls 1 lw 2
# ***** SECOND PLOT SETTINGS *****
# Remove previous customizations
unset tics
unset xlabel
unset ytics
unset ylabel
# New customizations
set border 8 ls 2
set y2label "Pressure [mbar]" tc ls 2
set y2range [-5:60]
set y2tics tc ls 2
set my2tics 4
# Labels
set label "Compliance : 15 [ml/mbar]" at 0.95,100.0 offset 0, 0
set label "Resistance : 5 [mbar/l/sec]" at 0.95,100.0 offset 0,-1
set label "PEEP : 5 [mbar]" at 0.95,100.0 offset 0,-2
set label "Inspiratory Pressure : 30 [mbar]" at 0.95,100.0 offset 0,-3
# Second plot itself
plot $PressureData axes x1y2 w l ls 2 lw 2
unset multiplot
The result:

Answer 3

By default font usually looks different and axis titles are centered.
