带有误差线的Gnuplot条形图 [英] Gnuplot Bar chart with error bars

问题描述

我有以下数据

Name   Value of the bar   Confidence interval
A      0.62               [0.59 0.63]
B      0.64               [0.54 0.72]
C      0.51               [0.46 0.67]
D      0.33               [0.25 0.36]

我试图将其绘制为条形图，其中A，B，C和D分别标记每个条形，并带有和错误条形.

I tried to plot it as a bar chart with A,B,C and D labeling each bar and with and error bar.

通过使用

使用1绘制"my.dat"图；带框的我只得到一个条形图.有人可以帮我吗?

plot "my.dat" using 1; with boxes I only get a bar chart. Can someone help me?

推荐答案

如果还需要错误栏，则必须添加第二张具有 yerrorbars 绘图样式的绘图.括号在数据文件中不是很方便，因此我用 sed 命令将其删除:

If you also want errorbars, you must add a second plot with the yerrorbars plotting style. The brackets aren't very handy in the data file, so I remove them with a sed command:

set style fill solid
set boxwidth 0.8
set yrange [0:*]
unset key
plot "< sed 's/[][]//g' my.dat" using 0:2:xtic(1) with boxes, \
     '' using 0:2:3:4 with yerrorbars lc rgb 'black' pt 1 lw 2
