ybar 图中的一个条形内的粗体字体

Question

我正在尝试使用粗体字体渲染此图条形内的白色文本。我可以将 tikzlabels 设为粗体，但不能将条形内的内容设为粗体...您知道解决这个问题的方法吗？

以下是 mwe：

\usepackage{tikz,pgfplots,pgfplotstable}

\definecolor{rgpoly}{RGB}{185,30,50}

Answer 1

关键是

nodes near coords style={font=\boldmath},

如同

\documentclass{standalone}
\usepackage{tikz,pgfplots,pgfplotstable}
\pgfplotsset{compat=1.9} % 1.17 would be better
