\pgfmathprintnumber 超出轴值的条形值标签

我尝试仅标记超出轴的 y 值，而不标记其余部分（如下图所示）。有什么建议可以实现吗？在此处输入图片描述

我的 MWE（感谢@杰克)：

答案1

要实现这一点，需要两个步骤。首先，您需要nodes near coords从参数列表中删除 及其值\begin[axis]。（这将删除全部标签）。接下来，您需要向带有绿色条nodes near coords的个体中添加\addplot标签。这样做，您将无法为所有绿色条添加标题，这显然不是您真正需要的。

但是，有一个技巧可以只nodes near coords在您想要的特定坐标上添加值。（您从索引 0 开始计算坐标）。因此，在这种情况下，(EP(FW),48.56)是第六个项目，但索引为 5。从上面获取值{\pgfmathprintnumber{\rawy}}并将其包装起来，\ifnum...\fi如下例所示：
