我正在尝试按如下方式定位我的图像。问题是，当我删除位于原点的黑点时，我的图像的定位就乱了。我的第二个问题是，我将图像与文本混合。现在它从文本后开始，但不与文本内联。这就是我想要实现的。这是我的代码：

\begin{itemize}
\item It is more common to visualize surfaces in 3D
\item Example:
\begin{subequations}
\begin{empheq}[box=\widefbox]{align*}
&f(x,y)=sin(x)cos(y), \\
&x\in [-\pi , \pi]; y \in[-\pi ,\pi ]
\end{empheq}
\end{subequations}
\item \textcolor{orange}{\textbf{surf}} puts vertices at specified points in space x,y,z, and connects all the vertices to make a surface
\item The vertices can be denoted by matrices X\tikz[na] \coordinate (s-mat); ,Y\tikz[na] \coordinate (s-gray);,Z
\item How can we make these matrices
\begin{itemize}
\item loop (DUMB)
\item built-in function: \textcolor{orange}{\textbf{meshgrid}}
\end{itemize}
\end{itemize}
\tikzstyle{background grid}=[draw, black!50,step=.5cm]
\begin{tikzpicture}[show background grid]
\node [inner sep=0pt] (X) at (7,.50) {X};%\includegraphics[width=2cm]{X}
\node [inner sep=0pt](Y) at (9,1){Y};%\includegraphics[width=2cm]{Y}

以上是我想要的结果。下面是我的实际输出（根据 Sigur 的建议）。

我使用了 2 个\parboxes 并排插入。
