我需要绘制时间数据并像这张图一样阴影显示某些时间段
可以使用 tikz 吗？非常感谢
抱歉。我忘了附上我的身材了。很遗憾
“\filldraw[fill=gray!50!] (2005-01-14,-3) 矩形 (2006-02-14,3)；”
在我的例子中不起作用。

由于您没有为您的图提供任何公式，我假设这y =cos(pi*x)是图公式的示例。您可以简单地精确地使用\filldraw以下方法对要着色的网格部分进行协调：
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\usepgfplotslibrary{fillbetween}
\usetikzlibrary{patterns}
\begin{document}
\begin{figure}[h]
\centering
\begin{tikzpicture}
\begin{axis}%
[grid=both,
minor tick num=4,
grid style={line width=.1pt, draw=gray!10},
major grid style={line width=.2pt,draw=gray!50},
axis lines=middle,
enlargelimits={abs=0.2}
]
\filldraw[fill=blue!40!white, draw=black] (0,0) rectangle (0.5,1);
\addplot[domain=-1:3,samples=50,smooth,red] {cos(deg(pi*x))};
\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}
对于此功能，您将得到以下图表：
