\usepackage{pgfplots}

\usepackage{float}
\usepackage{adjustbox}  % This is to scale the entire figure so it doesn't mess up the spy

    \begin{enumerate}
        
        \item I'm talking about a figure. It's a great figure. Glorious, I might add\dots Here's the figure:
        \begin{figure}[H]
            \centering
            \begin{adjustbox}{width=0.65\textwidth}
                \begin{tikzpicture}[spy using outlines={circle, magnification=3, connect spies}]
                    \begin{axis}
                    [
                        xlabel={Temperature ($\unit{\celsius}$)},
                        ylabel={Consumption (litres per hour)},

                        axis lines=left,
                        legend style={at={(0.5,-0.3)}, anchor=north},
                        tick align=center
                    ]
                    
                    \addplot[black, dotted, ultra thick, domain=15:105, samples=100] {(770 / x)-1.325};

                    \coordinate (magnifier) at (axis cs:150,30);
                    
                    \end{axis}
                    
                    \spy[gray, size=3cm] on (spypoint) in node[] at (magnifier);
                    
                \end{tikzpicture}
            \end{adjustbox}
        \end{figure}
        
        \hrule  % This is just to give perspective on how the figure is centered.
        
        See? I said it was glorious, didn't I?

问题

我真正想要的只是图形（轴）居中，但间谍不居中（相对于页面）。

Answer 1

好棒的身材！

如果你添加overlay到 Ti钾Z 范围，即计算图形大小时不考虑范围边界框（它占据的物理空间）。

所以写

 \spy[gray, size=3cm,overlay] on (spypoint) in node[] at (magnifier);

会给你

请注意，由于您要求忽略图形从边框“溢出”的问题，因此它不会被注意到……因此您必须注意不要让它超出页面区域。
