我正试图在Boxes of the plot(绘制通过gnu情节)的中间写,但找不到一些优雅的方式。手动找到所有盒子的中间点是很繁琐的。请指导我搞清楚。

正如@Christoph在评论中提到的,plot ... w labels
是其中一个选项。唯一的额外成分"包括计算标签的位置。例如,可以举例如下:
set terminal pngcairo
set output 'fig.png'
fName='test.dat'
bw = 0.9
yMin = 50
yMax = 130
xMin = 2
xMax = 15
set boxwidth bw
set xr [xMin - bw/2:xMax + bw/2]
set yr [yMin:yMax]
#scale 0 makes sure that the tic marks don't "show up"
set format x "1 %.0f"
set xtics 2,1,15 rotate by -15 scale 0
set ytics 50,10,130 scale 0
set ylabel "TODO"
set xlabel "TODO"
set key top right
#place the labels in the "middle" with respect to the
#minimum on the y-axis
p \
100 t "Todo" lc rgb "black" dt 3, \
fName u 1:2 w boxes t "TODO" lc rgb "black", \
fName u 1:(($2-yMin)/2+yMin):(sprintf("%.0f", $2)) w labels t '' tc rgb 'dark-red'
假设数据文件test.dat
为:
2 100
3 75
4 74
5 76
6 74
7 78
8 92
9 98
10 75
11 105
12 118
13 120
14 122
15 122
