在gnuplot中设置图标题之间的间距

Question

我有一个gnuplot gif文件生成代码：

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

问题是情节标题很大，所以我需要在它们之间添加一些间距。我怎样才能使它发挥作用？

Answer 1

试试set key spacing <some number>。增加<some number>的值应该会增加标题之间的距离。
