Gnuplot - create high quality plot for publication

Open text editor and paste the following code and save the file as plot-gnu

#!/bin/bash

# Output file.pdf
file=trig

gnuplot << TOEND
# Setup output
set term postscript eps enhanced \
dashlength 4 \
linewidth 5 \
"Helvectica" 24\
color

set output "$file.eps"
#unset key
set yrange [-1.1:1.1]

set xlabel 'x'
set ylabel 'y'

# Format plot
p sin(x) t 'sin(x)'\
, cos(x) t 'cos(x)'

TOEND
epstopdf $file.eps
rm $file.eps



Make the code executable by running
chmod +x plot-gnu Run the code with
./plot-gnu You should now have a high quality plot in a file called trig.pdf A useful plot that shows all of the available (black and white) linetypes can be created with the following code. Follow the same steps as above. This code makes a file call linetypes.pdf. #!/bin/bash

# Output file.pdf
file=linetypes

gnuplot << TOEND
# Setup output
set term postscript eps enhanced \
dashlength 4 \
linewidth 5 \
"Helvectica" 24\
#color

set output "$file.eps"
unset key
set yrange [0:10]

set xlabel 'x'
set ylabel 'Linetype'

# Format plot

, 7 lt 7\
