我目前正在研究 gnuplot bar-stacked with patterns。我必须用颜色组合创建图案，但我想让边框保持黑色。怎么设置的？据我所知gnuplot在做
lc rgb "#006600" lt -1 fs 模式 1，\
和边框颜色也使用
液晶显示器
.
这是我的数据：
CS 31.73 18.32 20.78 22.88 1.97 1.29 0.90 2.01

这是我的 gnuplot 文件：
set term pos eps font 20
set style data histogram
set style histogram rowstacked
set key invert reverse above
set boxwidth 0.8
set format y "%.0f%%"
set border 3
set yrange [0:100]
set size 0.9 , 1.8
set label 1 "1092" at -0.3,103 font "Times-Roman, 17"
set label 2 "500" at 0.7,103 font "Times-Roman, 17"
set label 3 "1000" at 1.8,103 font "Times-Roman, 17"
set label 4 "500" at 2.8,103 font "Times-Roman, 17"
set label 5 "1000" at 3.8,103 font "Times-Roman, 17"
set label 6 "500" at 4.8,103 font "Times-Roman, 17"
set label 7 "500" at 5.8,103 font "Times-Roman, 17"
set output 'aspect.eps'
plot 'a3b-aspect' \
using($2):xtic(1) t "pattern 1" lc rgb "#006600" lt -1 fs pattern 1, \
'' using($3) t "pattern 2" lc rgb "#006600" lt -1 fs pattern 2, \
'' using($4) t "pattern 3" lc rgb "#330000" lt -1 fs pattern 3, \
'' using($5) t "pattern 4" lc rgb "#000099" lt -1 fs pattern 4, \
'' using($6) t "pattern 5" lc rgb "#000099" lt -1 fs pattern 5, \
'' using($7) t "pattern 6" lc rgb "#000099" lt -1 fs pattern 6, \
'' using($8) t "pattern 7" lc rgb "#000099" lt -1 fs pattern 7, \
'' using($5) t "pattern 3" lc rgb "#660000" lt -1 fs pattern 3, \
'' using($6) t "pattern 3" lc rgb "#990000" lt -1 fs pattern 3
这是我的输出：
如何使我的所有图案的边框颜色都是黑色的？谢谢
