如何删除轴和比例图以占据三维图中的整个空间

到目前为止我已经能够创作出以下情节：

\begin{figure}
    \centering
    \begin{tikzpicture}
    \begin{axis}[
    view={80}{30},
    axis equal,
    hide axis
    ]
    
    \addplot3[
    dashed,
    y domain=0:0,
    samples=200,
    domain=0:2*pi,
    ]
    ({cos(deg(x))},{sin(deg(x))},{0});
    
    \addplot3[
    thick,
    y domain=0:0,
    samples=200,
    domain=0:2*pi,
    ]
    ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))});
    
    \addplot3[
    y domain=0:0,
    samples=200,
    domain=0:2*pi,
    ]
    ({1+0.1*cos(deg(x))},{0.1*sin(deg(x))},{0});
    \end{axis}
    \end{tikzpicture}
    \caption{This is just a very long sentence. I want my graph to extend through the entire space available; nonetheless, there is a white space occupied by the axis I want to remove.}
    \label{fig:motion}
\end{figure}

产生以下内容（几乎正是我想要的）：

我拥有的

我可以隐藏轴，但它们占据的空间仍然存在。我希望我的绘图能够延伸到整个可用的水平长度（并且希望能够控制它）。

我想要的最终情节如下：

我想要的是

我还想在每条路径中添加箭头和文本。但我的主要问题是关于大小，如果它们不是那么简单，我可以稍后在 Google 上搜索如何添加它们。

谢谢

可以通过增加 来增加宽度width。由于您抑制了框架，因此获取全宽所需的值有点违反直觉，但可能比使用其他键更简单。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\usetikzlibrary{3d,arrows.meta}
\begin{document}
\begin{figure}
    \centering
    \begin{tikzpicture}
    \begin{axis}[width=1.25\textwidth,
    view={80}{30},
    axis equal image,
    hide axis,sp/.style={smooth cycle,
    samples y=0,domain=#1,
    samples=101},sp/.default=0:2*pi
    ]    
    \addplot3[sp,dashed] ({cos(deg(x))},{sin(deg(x))},{0});
    
    \addplot3[sp,thick] ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))});
    
    \addplot3[sp,thin] ({1+0.1*cos(deg(x))},{0.1*sin(deg(x))},{0});
    
    \addplot3[sp=pi-0.4:pi-0.05,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{-0.1})
        node[pos=0.5,font=\sffamily,below]{Magnetron};
    \addplot3[sp=-0.7:-0.5,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))+0.1})
        node[pos=0.5,font=\sffamily,above right]{Axial};
    \end{axis}
    \end{tikzpicture}
    \caption{This is just a very long sentence. I want my graph to extend through the entire space available; nonetheless, there is a white space occupied by the axis I want to remove.}
    \label{fig:motion}
\end{figure}
\end{document}

起初我以为[scale only axis]可以处理宽度，但它仍然为绘制点的整个立方体（域）留有空间。解决这个问题的唯一方法是追溯使用\resizebox，这也会使字体稍微大一些。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\usetikzlibrary{3d,arrows.meta}
\begin{document}
\begin{figure}
    \centering
    \resizebox{\textwidth}{!}{\begin{tikzpicture}
    \begin{axis}[scale only axis, width=\textwidth,
    view={80}{30},
    axis equal image,
    hide axis,
    sp/.style={smooth cycle,
    samples y=0,domain=#1,
    samples=101},sp/.default=0:2*pi
    ]    
    \addplot3[sp,dashed] ({cos(deg(x))},{sin(deg(x))},{0});
    
    \addplot3[sp,thick] ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))});
    
    \addplot3[sp,thin] ({1+0.1*cos(deg(x))},{0.1*sin(deg(x))},{0});
    
    \addplot3[sp=pi-0.4:pi-0.05,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{-0.1})
        node[pos=0.5,font=\sffamily,below]{Magnetron};
    \addplot3[sp=-0.7:-0.5,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))+0.1})
        node[pos=0.5,font=\sffamily,above right]{Axial};
    \end{axis}
    \draw[red] (current bounding box.south west) rectangle (current bounding box.north east);
    \end{tikzpicture}}
    \caption{This is just a very long sentence. I want my graph to extend through the entire space available; nonetheless, there is a white space occupied by the axis I want to remove.}
    \label{fig:motion}
\end{figure}
\end{document}

如果您不想改变字体大小，您可以通过两次绘图来计算所需的宽度。

请注意\redo，\scale和\box0是图形局部的。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\usetikzlibrary{3d,arrows.meta}
\begin{document}
\begin{figure}
    \centering
    \def\redo{\begin{tikzpicture}
    \begin{axis}[scale only axis, width=\scale\textwidth,
    view={80}{30},
    axis equal image,
    hide axis,
    sp/.style={smooth cycle,
    samples y=0,domain=#1,
    samples=101},sp/.default=0:2*pi
    ]    
    \addplot3[sp,dashed] ({cos(deg(x))},{sin(deg(x))},{0});
    
    \addplot3[sp,thick] ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))});
    
    \addplot3[sp,thin] ({1+0.1*cos(deg(x))},{0.1*sin(deg(x))},{0});
    
    \addplot3[sp=pi-0.4:pi-0.05,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{-0.1})
        node[pos=0.5,font=\sffamily,below]{Magnetron};
    \addplot3[sp=-0.7:-0.5,sharp plot,red,-{Stealth}] 
        ({cos(deg(x))},{sin(deg(x))},{0.3*sin(deg(7*x))+0.1})
        node[pos=0.5,font=\sffamily,above right]{Axial};
    \end{axis}
    \end{tikzpicture}}%
    \sbox0{\def\scale{1}\redo}% get width for scale=1
    \pgfmathsetmacro{\scale}{\textwidth/\wd0}% recompute scale
    \redo    
    \caption{This is just a very long sentence. I want my graph to extend through the entire space available; nonetheless, there is a white space occupied by the axis I want to remove.}
    \label{fig:motion}
\end{figure}
\end{document}
