将误差线添加到gnuplot中的直方图 [英] adding error bar to histogram in gnuplot

问题描述

我有一个看起来像这样的数据文件

I have data file which looks like this

#col 1     2     3     4     5     6     7
#bench                 #these are max and min values 
#mark     #bar1 #bar2  #for the prevoius 2 values 
NOSHARE.2 43032 139412 100 45000 130000 140000
FALSE_SHARE.2 7035 24101 5000 7500 24100 25000
SHAREDVAR.2 11316 10248 10000 12000 10000 12000

我能够使用gnuplot生成一个像这样的图形

I am able to generate a graph using gnuplot which looks like this

我需要将最大值和最小值作为错误栏添加到每个栏

I need to add max and min value as an error bar to each bar

这里是我的gnuplot脚本

Heres my gnuplot script

set output "truevsfalse.png"
set title " TRUE VS FALSE SHARING "
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 5 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
set xtics  norangelimit
set ylabel "NUMBER      OF      SHARING"
set xlabel "BENCHMARK"
plot 'truevsfalse.dat'  using 2:xtic(1)  title "true(synced and nonsynced)sharing (both vcpus)" , '' u 3   title "false sharing (both vcpus)"

我尝试过

plot 'truevsfalse.dat'  using($0- .05):2:4:5:xtic(1) with boxerrorbars  title "true(synced and nonsynced)sharing (both vcpus)" , '' using ($0+0.25):3:6:7 with boxerrorbars  title "false sharing (both vcpus)"

但是失败了，我只是得到了没有直方图条的误差线，或者如果我尝试了一点修改，图像就损坏了.
我在做什么?

But failed , I either get just the error bars without histogram bars or if I try to modify a bit the image corrupts.
What am I doing wtong?

谢谢

推荐答案

基本上，您需要叠加直方图和误差线图，但是，我看到问题出在使用xtic(1)，这使得很难叠加误差线图在箱形图上.

Basically, you need to overlay histogram and error bar plot, however, I see the problem is using xtic(1), which makes it difficult to overlay error bar plot on the box plot.

set xtics ('NOSHARE.2' 0, 'FALSE_SHARE.2' 1, 'SHAREDVAR.2' 2)
set bs 0.2 # width of a box
plot 'junk' u ($0-bs/2):2:(bs) w boxes title "true(synced and nonsynced)sharing (both vcpus)", \
     'junk' u ($0-bs/2):2:4:5 w yerror notitle, \
     'junk' u ($0+bs/2):3:(bs) w boxes title "false sharing (both vcpus)", \
     'junk' u ($0+bs/2):3:6:7 w yerror notitle
