如何设置 pgfplots 条形图中的轴？

我正在尝试设置一个pgfplots条形图，使其看起来像我用 Powerpoint 制作的图表。有人能帮我吗？谢谢

\documentclass{article}
\usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} 
\usepackage{graphicx}
\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}
[ xbar, y axis line style = { opacity = 0 }, axis x line = none, tickwidth = 0pt, enlarge y limits = 0.2, enlarge x limits = 0.02, nodes near coords, symbolic y coords = {Tool cost, Material cost,Processing cost }, legend style={at={(0.5,-0.15)},
        anchor=north,legend columns=-1},] 
\addplot coordinates { (1.43 ,Processing cost) (0.01,Material cost) (43.69,Tool cost)};
\addplot coordinates {  (2.43,Processing cost)  (0.01,Material cost) (8.81,Tool cost)};
\legend{CNC machining, AM}
\end{axis} 
\end{tikzpicture}
  \caption[Cost per part comparison with CNC machined and AM inserts]{Cost per part comparison with CNC machined and AM inserts}
\label{fig:brass_piechart}  
\end{figure}

\end{document}

此外，我在每个图形下画一条线，像这样

\decoRule{\widthof{\includegraphics[width=\textwidth]{CNCvsAM}}}

我该如何调整它以使用 7cm 的 pgfplot 宽度？

由于 所做的\decoRule只是画一条黑线，最简单的方法是将其作为 的一部分tikzpicture，例如添加

\draw [line width=0.4pt] ([yshift=-2pt]current bounding box.south west) -- (current bounding box.south east);

之后\end{axis}。根据您的喜好调整，或者如果不需要，则完全-2pt删除。[yshift=<value>]

对于其他部分，您只需对选项进行一些添加axis，请参阅下面代码中的注释。

    anchor=north,
    legend columns=-1,
    draw=none}
] 
\addplot coordinates { (1.43 ,Processing cost) (0.01,Material cost) (43.69,Tool cost)};
\addplot coordinates {  (2.43,Processing cost)  (0.01,Material cost) (8.81,Tool cost)};
\legend{CNC machining, AM}
\end{axis} 
\draw [line width=0.4pt] ([yshift=-2pt]current bounding box.south west) -- (current bounding box.south east);    
\end{tikzpicture}
  \caption[Cost per part comparison with CNC machined and AM inserts]{Cost per part comparison with CNC machined and AM inserts}
