条形图上的误差线 [英] Errorbars on bar-graph

问题描述

我正在尝试:一个漂亮的组条形图.我想要像这样的误差线(或您自己决定的误差线):

I'm trying to get: a nice bar graph of groups. I'd like error bars on each bar like this (or similar at your discretion):

我有办法:

ff =
             Medical eq    Patient   Hygiene   Near bed   Far bed
Direct        1.2759    0.9253    0.6092    1.0460    1.3276
Housekeeping  1.0833    0.2500    0.5833    2.1667    1.3333
Mealtimes      0        0.3000    0.7000    1.4500    0.5000
Medication    0.3694    0.7838    0.8919    1.5495    1.0541
Misc          0.1059    0.1294    0.4118    0.8000    0.8353
Personal      0.0370    0.4074    0.8148    1.2593    0.7037

标准偏差

ee =

2.0411    1.1226    0.8378    1.5007    1.3776
1.3114    0.4523    0.6686    2.4058    1.1547
     0    0.7327    1.3803    2.1392    0.6070
0.7499    0.9186    1.0300    1.2844    1.3062
0.4371    0.3712    0.7605    1.0212    0.6699
0.1925    0.6939    1.6417    3.5582    1.5644

相反，我得到了:

通过使用:

bb=bar(ff'); hold all
data=repmat([1:6]'*ones(5,1)',1,1)
er=errorbar(data, ff, ee, '.')

我读到我必须找到每个条的中心吗?太疯狂了！有什么解决方法吗?

I read I have to find the centre of each bar? That's crazy! Any workaround?

推荐答案

这真的不是那么疯狂！

您可以仅将errorbar与现有数据结合使用.

You can just use errorbar with the data that you have readily available.

此代码通过为每个组加1，为组内的每个条加1/7，来计算正确的位置.

This code computes the correct locations, by adding 1 for every group and 1/7 for each bar within a group.

for i = 1:5
    j = 1:6; 
    x = -0.5 + i + 1/7 * j; 
    errorbar(x, ff(j,i), ee(j,i), '.'); 
end

结果:

(省去了标签，但是这似乎与您要查找的内容非常相似)

(Leaving out the labels, but otherwise this seems pretty similar to what you were looking for)
