Gnuplot xtic 标签对齐调整

Question

我正在尝试为以下数据制作多图：

col,   col1 , col2, col3
20,    4.9, 17.1, 78.1 
25,    4.0, 22.0, 74.0 
30,    2.0, 17.0, 81.0 
35,   11.5, 21.7, 66.8 
40,    4.7, 18.0, 77.4 
45,    3.8,  8.9, 87.3 
50,    0.6, 17.3, 82.1 
55,    2.0,  3.4, 94.6 
60,    1.0,  1.3, 97.6

使用 Gnuplot 脚本

set terminal pngcairo
set output "num.png"
set style data histogram
set style histogram rowstacked
set style fill solid
set key outside
set boxwidth 0.5

set size 1,1
set origin 0,0

set datafile separator ","
set multiplot layout 4,1 
set size 1,0.25
set origin 0,0.25
set xtics border font ",6"
set lmargin at screen 0.1
set tmargin at screen 0.25
set bmargin at screen 0.1
set rmargin at screen 1
plot for [COL=2:4] 'num.bat' using COL:xtic(1) ti col
unset multiplot
exit

我得到了下面的图像。

我喜欢让 x 轴标签 20、25、30...更靠近 x 轴。我有多少尝试远离它。有人可以为此提出解决方案吗？
