我制作了以下xbar图表：
正如你所见，尽管2019 年第四季度首先绘制的系列（深蓝色），它出现在2020 年第一季度系列（橙色）。我该如何修复此问题？
请注意，图例顺序是正确的 - 4Q19 位于 1Q20 之上。为什么这没有反映在图中？
生成上述内容的代码：

\usepackage{pgfplotstable}
\usepgfplotslibrary{dateplot}
\pgfplotsset{compat=1.8}

解决方案是使用reverse legend（h/t这里）然后交换情节顺序：
\documentclass{standalone}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{dateplot}
\pgfplotsset{compat=1.8}
%colors
\usepackage{color} % colors
\usepackage{xcolor}
\definecolor{cone}{RGB}{18,32,132} % blue
\definecolor{ctwo}{RGB}{255,153,0} % orange
\definecolor{ctwol}{RGB}{255, 192, 0} % lighter orange
\definecolor{cthree}{RGB}{0, 176, 80} % green
\definecolor{cfour}{RGB}{255, 0, 0} % red
\definecolor{cfive}{RGB}{0, 176, 240} % light blue
\begin{document}
\pgfplotstableread[col sep=comma]{
