在gnuplot的条形图上添加误差线 [英] Adding error bars on a bar graph in gnuplot

问题描述

我要使用gnuplot条形图绘制以下文件:

I have the following file I want to plot using gnuplot bar graphs:

Function X X-ERROR Y Y-ERROR
A 1.311539 0.066268 1.000000 0.000000
(a1,b0)  1.325429 0.083437 1.010926 0.016710
(a.9,.b1)  1.134640 0.040017 1.276168 0.060281
(a.8,.b2)  1.078336 0.058529 1.346358 0.054645
(a.7,.b3)  1.035866 0.060660 1.318395 0.018087
(a.6,.b4)  0.982717 0.047363 1.196714 0.047427
(a.5,.b5)  0.962423 0.051994 1.127991 0.044731
(a.4,.b6)  0.953673 0.046014 1.139608 0.044726
(a.3,.b7)  0.948948 0.050462 1.169209 0.044333
(a.2,.b8)  0.941013 0.047166 1.198138 0.045844
(a.1,.b9)  0.929961 0.057801 1.328111 0.088813
(a0,b1)  0.966331 0.036079 3.289381 0.213192
B  1.000000 0.000000 3.321802 0.121290

我可以使用以下方法来完美地绘制图形:

I can manage to plot the graph perfectly using:

plot 'file.dat' using 4:xtic(1) title col, \\
        '' using 2:xtic(1) title col;

但是，我想使用第3列和第5列来表示我一直计算出的置信区间.有帮助吗?

However I would like to use columns 3 and 5 to represent the interval of confidence that I always calculated. Any help?

谢谢！

推荐答案

假设您要绘制带有相关误差线的并排条形图，我将使用以下内容:

Assuming you want to draw side-by-side bar charts with associated error bars, I would use the following:

set xrange [-0.5:12.75]
set xtic rotate by -45
set boxwidth 0.25
plot 'file.dat' using ($0-.05):4:5:xtic(1) with boxerrorbars title col, \\
     '' using ($0+0.25):2:3 with boxerrorbars title col

这个想法只是要抵消x轴上的两个量度之一.

The idea is just to offset one of the two measures on the x-axis.
