目前，我的条形图中的所有标签都没有显示在条形上方，我不知道为什么。此外，标签似乎自动使用科学记数法，我也不知道如何更改。
这是我当前的代码：
\documentclass[12pt]{article}
\usepackage{fancyhdr}
\renewcommand{\familydefault}{\sfdefault}
\renewcommand*{\ttdefault}{\familydefault}
\usepackage[paperwidth=42cm,paperheight=29.7cm,left =1cm, top = 1cm, right =1cm, bottom = 1cm ,marginparwidth=0cm, includeheadfoot,headheight=66pt, headsep=0cm]{geometry}

\definecolor{customcolor}{HTML}{1d5893}

\begin{tikzpicture}
\pgfplotscreateplotcyclelist{defaultCycle}{%

};
%Total,Curie,Franklin,Angela,Ursula,Warner,Newton,Hyems,Repton
\end{axis}
\end{tikzpicture}
\end{minipage}
\end{document}
和当前输出：
我希望所有标签都位于条形图上方，并且不采用科学记数法。
答案1
这对于数字格式很有效：\pgfkeys{/pgf/number format/fixed}
将其更改为\pgfkeys{/pgf/number format/.cd,fixed,precision=0}另外可解决以下评论中的舍入请求。
我在下面的工作示例中标记了该行
对于条形图上方的标签，我通过 引入了一个假列\pgfplotstableset{creat on use ...}，这需要事先将表格读入宏中。实际上pgfplotstableread可能不需要这样做。最后，第二个图覆盖实际的条形图，从而生成标签。因此，该nodes near coords选项从轴选项移到了特定图。否则，第一个图也会在图表下方创建标签。
