我有几条曲线需要展示，并且想在同一张幻灯片上以项目符号列表同步展示它们。
这个列表很好，但是不同的曲线并不按照我想要的顺序排列，即使我切换了顺序。
如何继续？非常感谢以下代码：

我建议使用tikz 库visible on=<...>中的选项overlay-beamer-styles：
\documentclass{beamer}

\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\pgfplotsset{compat=newest}
% customisations
\def \calR{\mathcal{R}}

\definecolor{redTelecom}{RGB}{191,18,56}
\mode<presentation>{}
\usetikzlibrary{overlay-beamer-styles}
\begin{document}

ymin = 0.988,
ymax = 0.9942,
x tick label style = {font = \Large},
y tick label style = {font = \Large},
y tick label style={
/pgf/number format/precision=4

legend style = {draw=none, legend columns = 2, legend pos = north west, font = \Large},
]
\addplot [mark = none, color = gray,visible on=<2->] coordinates {

\addlegendentry[visible on=<2->]{$R$}
