现在我们可以看到文本Clusters-2, Clusters-8和Clusters-16重叠了。我想知道我该怎么做才能使它不重叠并出现在栏下？我认为问题出在bar shift我添加到代码中。
谢谢 ！
==更新==
我可以编写如下代码 -
\addplot [bar shift=-0.3cm, satPointsColor,fill=satPointsColor,nodes near coords=2-clusters,nodes={xshift=-3mm}] table[x=Clusters,y=2] {Figures/experiments/julien/satPoints.txt};
但是，标签对齐不太好。
答案1
为了解决这个问题，我建议按以下方式重新排列表格：
表格.txt
Clusters satPoints unsatPoints timedoutPoints
1 1 5 0
5 3 37 0
9 5 49 1
13 2 3 6
17 1 4 0
2 0 9 0
6 0 8 6
10 2 8 4
14 0 3 2
18 2 4 5
3 0 9 0
7 0 9 0
11 0 3 6
15 0 1 0
19 1 5 4
并简化原始代码（唯一肮脏的部分涉及手动定位的 x 标签 1,5,10,15,20）：
