我面临新的挑战，渴望学习有关 tikz 的知识。现在我需要参考图片的每个部分，我正在查看各种代码。下面是我想要实现的原始代码。我附上了一张图片以便更好地理解。
\documentclass[xcolor=dvipsnames, aspectratio=169, 11pt]{beamer}
\usepackage{beamerthemeshadow}
\usepackage[absolute,overlay]{textpos}
\usepackage{tikz} \usetikzlibrary{tikzmark,calc}
\begin{document}
\section{}
\begin{frame}
\frametitle{Components of Figure}
\framesubtitle{Code}
\scriptsize
\begin{columns}[T] % align columns
\begin{column}{0.5\textwidth}
\color{Black}
\texttt{import numpy as np\\
import matplotlib.pyplot as plt\\
from matplotlib.ticker import AutoMinorLocator, MultipleLocator\\
np.random.seed(19680801)\\
X = np.linspace(0.5, 3.5, 100)\\
Y1 = 3+np.cos(X)\\
Y2 = 1+np.cos(1+X/0.75)/2\\
Y3 = np.random.uniform(Y1, Y2, len(X))\\
fig = plt.figure(figsize=(8, 8))\\
ax = fig.add\_subplot(1, 1, 1, aspect=1)\\
def minor\_tick(x, pos):\\
~~~~if not x \% 1.0:\\
~~~~~~~~return ""\\
~~~~return f"{x:.2f}"\\
ax.xaxis.set\_major\_locator(MultipleLocator(1.000))\\
ax.xaxis.set\_minor\_locator(AutoMinorLocator(4))\\
ax.yaxis.set\_major\_locator(MultipleLocator(1.000))\\
ax.yaxis.set\_minor\_locator(AutoMinorLocator(4))\\
% # FuncFormatter is created and used automatically
% #ax.xaxis.set\_minor\_formatter(minor\_tick)
}
\end{column}%
\hfill%
\begin{column}{.5\textwidth}
\texttt{ }
\begin{figure}
\centering
\includegraphics[height=0.7\textheight]{Img/components_of_graphs_1.png}
\end{figure}
\end{column}%
\end{columns}
\end{frame}
\end{document}
我正在阅读下面的代码
\documentclass{article}
%\usepackage{showframe}
\usepackage{tikz}
\begin{document}
\noindent
\begin{tikzpicture}
\node [anchor=west] (note) at (-1,3) {\Large Note};
\node [anchor=west] (water) at (-1,1) {\Large Water};
\begin{scope}[xshift=1.5cm]
\node[anchor=south west,inner sep=0] (image) at (0,0) {\includegraphics[width=0.7\textwidth]{../images/EiffelWide.jpg}};
\begin{scope}[x={(image.south east)},y={(image.north west)}]
\draw[red,ultra thick,rounded corners] (0.48,0.80) rectangle (0.55,0.95);
\draw [-latex, ultra thick, red] (note) to[out=0, in=-120] (0.48,0.80);
\draw [-stealth, line width=5pt, cyan] (water) -- ++(0.4,0.0);
\end{scope}
\end{scope}
\end{tikzpicture}%
\end{document}
但无法与之联系起来。所以在这里问你。

以下是您可以使用的操作tikzmark：
\documentclass[xcolor=dvipsnames, aspectratio=169, 11pt]{beamer}
\usepackage{beamerthemeshadow}
\usepackage[absolute,overlay]{textpos}
\usepackage{tikz} \usetikzlibrary{tikzmark,calc}
\begin{document}
\section{}
\begin{frame}
\frametitle{Components of Figure}
\framesubtitle{Code}
\scriptsize
\begin{columns}[T] % align columns
\begin{column}{0.5\textwidth}
\color{Black}
\texttt{import numpy as np\\
import matplotlib.pyplot as plt\\
from matplotlib.ticker import AutoMinorLocator, MultipleLocator\\
np.random.seed(19680801)\\
X = np.linspace(0.5, 3.5, 100)\\
\tikzmarknode{Y1}{Y1 = 3+np.cos(X)}\\
\tikzmarknode{Y2}{Y2 = 1+np.cos(1+X/0.75)/2}\\
\tikzmarknode{Y3}{Y3 = np.random.uniform(Y1, Y2, len(X))}\\
fig = plt.figure(figsize=(8, 8))\\
ax = fig.add\_subplot(1, 1, 1, aspect=1)\\
def minor\_tick(x, pos):\\
~~~~if not x \% 1.0:\\
~~~~~~~~return ""\\
~~~~return f"{x:.2f}"\\
ax.xaxis.set\_major\_locator(MultipleLocator(1.000))\\
ax.xaxis.set\_minor\_locator(AutoMinorLocator(4))\\
ax.yaxis.set\_major\_locator(MultipleLocator(1.000))\\
ax.yaxis.set\_minor\_locator(AutoMinorLocator(4))\\
% # FuncFormatter is created and used automatically
% #ax.xaxis.set\_minor\_formatter(minor\_tick)
}
\end{column}%
\hfill%
\begin{column}{.5\textwidth}
\texttt{ }
\begin{figure}
\centering
\includegraphics[height=0.7\textheight]{components_of_graphs_1.png}
\end{figure}
\end{column}%
\end{columns}
\begin{tikzpicture}[overlay,remember picture]
\draw[blue,->] (Y1) to[out=0,in=180] (9.9,5);
\draw[red,->] (Y2) to[out=0,in=200] (9.9,1.4);
\draw[green!50!black,->] (Y3) to[out=0,in=200] (9.5,2.5);
\end{tikzpicture}
\end{frame}
\end{document}
当然，您可以调整线条的参数：更改[out=<>,in=<>]、添加looseness，甚至创建更复杂的贝塞尔曲线。无论您需要什么。
