答案1

要将百分号添加到标签，您可以使用nodes near coords={\pgfmathprintnumber\pgfplotspointmeta\,\%}。请注意，如果您将其添加到轴，它还将应用于您添加的图的标签，以添加“道路”、“铁路”和“管道”的标签。因此，您需要将这些标签的选项重置为默认的nodes near coords={\pgfmathprintnumber\pgfplotspointmeta}。

为了对齐框尺寸太小的标签，您可以使用选项coordinate style/.condition并使用条件表达式仅选择相关标签，然后可以为其指定特定样式。不过，我不确定第三组中第二个栏的解决方案是否最佳。
