如何将我的 tex 代码中的第 5 个标签“49.2”移位 2 毫米

Question 1

这可能不是最好的解决方案，但对于仅有视图数据点的图来说，将线和标记放在不同的图中并单独调整节点位置就可以完成工作。

Question 2

您可以使用visualization depends on。添加

visualization depends on={ifthenelse(\coordindex==4,2mm,0) \as \nncshift}

在axis选项中，在every node near coord样式中添加

xshift=\nncshift

\coordindex正如您所料，是坐标的索引，从 0 开始计数。因此，第五个坐标的索引为 4。

如果您想要将第一个和第六个标签稍微左移，您可以嵌套两个ifthenelse语句，如下所示：

visualization depends on={ifthenelse(\coordindex==4,2mm,ifthenelse(\coordindex==0||\coordindex==5,-2mm,0)) \as \nncshift}

另一条评论：不要使用\addplot plot[..]，而只使用\addplot [..]，或\addplot +[..]。+表示设置附加到默认设置。plot关键字用于纯 TikZ，例如\draw plot ...

（代码格式当然是个人喜好，我更喜欢使用更多行，因此重新格式化。）
