我如何将图片插入环境问题并对齐它？

Question

我正在尝试将图片插入环境问题并像这样对齐

我试过

\documentclass{article}
\usepackage{amsmath}
\usepackage{enumerate}
\usepackage{amsthm}
\theoremstyle{definition}
\usepackage{graphicx}
\newtheorem{ex}{Problem}
\begin{document}
\begin{ex}
\begin{figure}
    \centering
    \begin{minipage}{0.45\textwidth}
    I want to put the picture align with the first row of Problem. I want to put the picture align with the first row of Problem. I want to put the picture align with the first row of Problem. I want to put the picture align with the first row of Problem. I want to put the picture align with the first row of Problem.
    \begin{enumerate}[A]
        \item First line.
        \item Second line.
        \item Third line.
        \item  A long line.
    \end{enumerate}
    \end{minipage}\hfill
    \begin{minipage}{0.45\textwidth}
        \centering
        \includegraphics[width=0.9\textwidth]{pic_01} % second figure itself
        \caption{second figure}
    \end{minipage}
\end{figure}
\end{ex}

\end{document}

并得到

这不是我想要的。我怎样才能得到正确的结果？

这是我插入的图片。

代码制作图片

\documentclass[12pt]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{fillbetween}
\usetikzlibrary{patterns}
\pgfplotsset{compat=1.9}
\usepackage{fouriernc}

\begin{document}
\begin{tikzpicture}
\begin{axis}
[
declare function={Y(\x)=(\x^3 - 3*\x^2 + 2);},
xticklabels={},yticklabels={},
axis line style = very thick,
    axis lines = center,
    xlabel=$x$,ylabel=$y$,
    xtick={-1, 0, 1,3},
        domain=-1.5:3.5,
        ymin=-2.5,
        ymax=2.5,
        xmin=-1.5,
        xmax=3.5,
    samples=100,xtick distance=1,
ytick distance=1,unit vector ratio*=1 1 1,
    width=11cm,
    grid=major,
    grid style={gray!30}]
\addplot [black, thick,name path =B] {Y(x)};
\addplot [black, mark=*,only marks,samples at={-1,0,1,2,3,4}] {Y(x)};
\node at (axis cs:-0.25, -0.25) {$O$} ;
\node at (axis cs:2, 0.2) {$2$} ;
\node at (axis cs:-0.2, 2.2) {$2$} ;
\node at (axis cs:-0.2, -2.2) {$-2$} ;
\addplot[name path =A] {0}\closedcycle;
\addplot[color=black,fill=red, pattern=north east lines,  domain=0:1,samples=100] fill between[of=A and B,soft clip={domain=0:2},];
\pgfplotsinvokeforeach{-1,2,3}{
\draw [black,dashed,thick](axis cs:#1,{Y(#1)}) -- (axis cs:#1,0); 
       \draw [black,dashed,thick](axis cs:#1,{Y(#1)}) -- (axis cs:0,{Y(#1)});
}
\addplot [thick] coordinates {(2,-2) (2,0)};
\end{axis}
\end{tikzpicture}
\end{document} 

Answer 1

几点：

1. 环境ex必须进入第一个minipage

2. 不需要figure环境，图没有标题。即使有，我也会\captionof在第二个里面使用minipage。

3. 将 s顶部对齐minipage，并将 向下移动\includegraphics。

4. 用于enumitem定制枚举。

一个替代解决方案，考虑您绘制的图表pgfplots。图表的代码已更改，可以根据您的需求放置。其中还考虑了pgfplots包的最新版本，并相应地简化了代码。

\documentclass{article}
\usepackage{fouriernc}
\usepackage{amsmath, amsthm}
\theoremstyle{definition}
\newtheorem{ex}{Problem}

\usepgfplotslibrary{fillbetween}
\usetikzlibrary{patterns}

\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
