我有gnuplot直方图的问题。 我有文件数据,想手动创建xtics。 这是我的数据:
5 10 15 20 25 30 35
这是我的gnuplot:
set terminal pngcairo enhanced font "arial,10" fontscale 1.0 size 500, 350
set output 'histograms.2.png'
set boxwidth 0.9 absolute
set style fill solid 1.00 border lt -1
set key inside right top vertical Right noreverse noenhanced autotitles nobox
set style histogram clustered gap 1 title offset character 0, 0, 0
set datafile missing '-'
set style data histograms
set xtics border in scale 0,0 nomirror rotate by -45 offset character 0, 0, 0 autojustify
set xtics norangelimit font ",8"
set title "testing"
plot 'histogram2.dat' using($0):xtic("sdaf") title "Legend 1", \
'' using($2):xtic("sdasa") title "Legend 2", \
'' using($3):xtic("sdSs") title "Legend 3", \
'' using($4) title "Legend 4", \
'' using($5) title "Legend 5", \
'' using($6) title "Legend 6", \
'' using($7) title "Legend 7"
在我当前的图表中,第一行无法显示在图表中。 另外,我想在x轴上制作标签,并且所有条形图都有相同的颜色。
这是我当前的输出:

我希望我理解你的问题。您可以执行以下操作:
像这样安排你的数据文件(比如在file1.dat中):
"Legend 1" 5
"Legend 2" 10
"Legend 3" 15
"Legend 4" 20
"Legend 5" 25
"Legend 6" 30
"Legend 7" 35
然后在你的Gnuplot脚本中有以下内容:
file1 = "file1.dat"
set style data histogram
set style histogram clustered gap 1
set ylabel "Ylabel" font ",18" offset character 2.5,0,0
set grid y
set yrange[0:40]
set xtics border in scale 0,0 nomirror rotate by 90 offset character -1, -4, 0
set ytics (0, 10, 20, 30, 40)
set boxwidth 0.9 absolute
set style fill transparent solid 0.8 noborder
set key outside right top vertical Left
plot newhistogram , file1 u 2:xtic(1) t "My Legend" lc rgbcolor "blue" lt 1

也许问题在这里 - >使用($ 0):xtic(" sdaf")title" Legend 1", 将其设置为$ 1而不是$ 0
