I have a gnuplot gif file generation code:
set terminal pngcairo font 'DroidSerif'
set output "summary2.gif"
set xtics font ", 15"
set ytics font ", 15"
set key font ",18"
set key top right
set xlabel "Data width in bytes" font ",20"
set ylabel "Summary size" font ",20"
set title "Size comparison" font ",25"
plot "summary2.data" using 1:4 title "BF Complete" w lp, "summary2.data" using 1:3 title "Labeled" w lp, "summary2.data" using 1:5 title "Complete" w lp, "summary2.data" using 1:2 title "BF" w lap
The issue is that the plot titles are large so I need to add some spacing between them. How can I make it work?

set terminal pngcairo font 'DroidSerif,15'. You'll anyway need to make some adjustments, but maybe less. - Christoph
