標簽在gnuplot中重疊

Question

有一個數據文件，我想在條形圖中添加標簽，但不幸的是標簽覆蓋在第一個條形上方，我無法弄清楚如何為每個標簽添加偏移量：

set xrange[0:30]
set y2tics font "Arial,8" mirror
#set y2tics rotate # rotating the y2ticks alongside with the y-axis
set xtics font "Arial,6"
#set datafile separator "\t"
set boxwidth 0.5 absolute # balkengroesse
set bmargin 0.6
set tmargin 0
set lmargin 0.9
set rmargin 0
set title "RTF History Analysis" font"Arial,9"
set ylabel "Max RTF" font"Arial,9" noenhanced
#set xlabel "Timestamp" font"Arial,9" noenhanced
#set xtics rotate 90 # turn the text to the vertical position
set style data boxes  # boxplot
set style fill solid 0.5 noborder 
set multiplot layout 3,1 # 3x vertical 1x horizontal

set grid xtics y2tics
set logscale y
set grid my2tics
set yrange[0.001:6500]
set logscale y2
set my2tics 10
unset ytics
set format "10^{%L}"
set xtics rotate by 50 offset -4.5,-3.00
set format y
plot "history_file.txt" u 7:xticlabels(2) w boxes lc rgb"blue" notitle, \
     "history_file.txt" u 7:2:3 w labels rotate left font "Arial,6" lc rgb"blue" notitle

Answer 1

嘗試

plot 'data' u  7:xticlabels(2) w boxes, '' u (column(0)):(.5):3 with labels

將標簽與盒子放在相同的高度（y = 0.5）。

要讓標簽跟隨盒子的高度，請嘗試

plot 'data' u  7:xticlabels(2) w boxes, '' u (column(0)):(0.01 +$7):3 with labels
