TiKZ 条形图中误差线的位置

Question

救命！我似乎无法将误差线的位置放在每个条形图的正上方。另外，出于某种原因，我的图例似乎也偏离了位置。

Answer 1

我还没有找到最佳方法，但在本例中它是有效的。以下是改进列表：

1. 我改成xscale = 1.45了width=12cm, height=6cm。
2. 我xshift在选项中添加了猜测的尺寸error bar style（两次）。
3. 我注释掉了该inputenc包，并将变音字符解码为 TeX 字符串（两次），现在该文件可以以所有主要格式运行latex，例如通过lualatex sample.tex。

我附上了我的努力成果和 PDF 文件的预览。
