如何在GNUPlot图中的每个条上给出文本

Question

我想在我的图表中垂直地在每个栏上添加200,300,600,800等文字。这是我的代码。

set title font ", 25" 
set xlabel "FEATURE LENGTH"
set xlabel font ",25"
set ylabel "ACCURACY(%)"
set yrange [45:76]
set ylabel font ",25"
set ytics font ", 25" 
set boxwidth 0.98
set key spacing 3
set key font ",25"



set style fill pattern 10 border lt -1
set style histogram errorbars gap 1 lw 0 

set key inside top center horizontal font "Helvetica, 25" width 1.8
set style histogram clustered #gap 5 title  offset character 0, 0, 0
set xtics font ", 25" 
set xtics ("F1" 0, "F2" 1, "F3" 2, "F4" 3, "F5" 4, "F6" 5, "F7" 6, "F8" 7, "F9" 8)
set style data histograms

plot "best_feature_pos.dat" using 1 t "{/Symbol a}", "" using 2 t "{/Symbol b}"
set output 'best_feature_pos10.eps'
set terminal postscript eps enhanced black
replot

这是我的数据文件

72.9    73.6
73.9    72.8
70.6    70.9
64      64
66      65.4
59      0
57.4    0
45.8    0
64.8    0

任何人都可以帮我找到解决方案???

Answer 1

您可以使用set label在地块上定位文字，例如：

set label 1 '200' front at screen 0.15,0.5 rotate by 90 font "Arial,20"
set label 2 '300' front at screen 0.16,0.5 rotate by 90 font "Arial,20"
# etc. 

这需要一些手动调整才能将标签放在正确的位置。
