堆积条形图中的小值无法正常显示

堆积条形图中的小值无法正常显示

问题： 我希望 (a) 和 (b) 条形图中 N=48 的小值 (5% 和 6%) 能够正确显示，而不是显示在网格上。我尝试更改限制，增加尺寸，但不幸的是没有任何效果。有人能帮我解决这个问题吗？

您可以根据 的值添加一些水平空间\pgfplotspointmeta。此宏存储在低级浮点数中，不直接适用于数字比较，但 pgfplots 还提供了\pgfplotspointmetatransformed定点表示，其缩放比例在 0 到 1000 之间。在这种情况下，您可以检查值是否小于 10%，例如，在缩放版本中，这意味着您检查值是否 <100。在这种情况下，您可以在打印值之前添加例如 4pt：

nodes near coords={\pgfmathparse{less(\pgfplotspointmetatransformed,100)}%
\ifnum\pgfmathresult=1%
\hspace{4pt}%
\fi%
\pgfkeys{/pgf/number format/precision=0}\pgfmathprintnumber{\pgfplotspointmeta}\%}

当然，这应该只发生在条形图的左侧，否则右侧的 1% 和 2% 值将被推到图外。为此，您可以只对有问题的线添加检查\addplot，这将覆盖默认规范。
