我知道可以只在条形图顶部显示总和并删除堆积条形图中的其他值（如附图所示），但我无法弄清楚我的代码出了什么问题。
这是我的 MWE：
\documentclass[a4paper]{report}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{dateplot}
\pgfplotsset{
compat=newest}
\pgfplotsset{
show sum on top/.style={
/pgfplots/scatter/@post marker code/.append code={%
\node[
at={(normalized axis cs:%
\pgfkeysvalueof{/data point/x},%
\pgfkeysvalueof{/data point/y})%
},
anchor=south,
]
{\pgfmathprintnumber{\pgfkeysvalueof{/data point/y}}};
},
},
}

答案1
第二轴中的以下几行使所有坐标都显示值。
nodes near coords={
\pgfmathprintnumber[precision=0]{\pgfplotspointmeta}},
替换为
nodes near coords={},
抑制它们。实际上，您不需要两个轴分别绘制负数和正数。可以使用stack negative=on previous,选项来完成。
