我想使 yaxis 上的特定刻度标签移动足够远，以便它们不会与堆积条形图中的条形重叠，但同时我希望所有标签保持相同的“明显”分离距离（最后一个条件我可以适应其他选项）。
我还希望得到额外的帮助，使 xaxis 与图像边框分离（这样看起来更对称）。
下面我附上了一张图片来说明我需要修复的问题
我相信可以通过实现“可视化取决于”来实现，但不确定如何在代码中引入这一点。

提前感谢您的帮助，这个社区太棒了！

这里有一些可以按照您想要的方式附加这些文本的东西。不幸的是，此时您的代码似乎无法运行，因为表格没有您使用的列。所以我做了一些东西。关键点是
\addplot [only marks,mark size=0pt,nodes near
coords=text~\the\numexpr\coordindex+1,nodes near coords style={anchor=east}]
table[x expr={-0.01},y expr=\coordindex] {\testdata};
自动将节点放置在您喜欢的位置。

或者对于您更新的示例：从行中读取内容Species并使用另一个技巧。
