latex - 使用 LaTeX 进行图形缩放 - 圆形变成椭圆

Question

我有以下创建图形并绘制圆圈的 LaTeX 代码。然而，这个圆看起来不像一个圆，而是一个椭圆。我认为这是因为我的图表是如何设置的。有什么方法可以保持图形的当前外观/缩放比例，同时使圆圈看起来更像一个圆圈（我在下面包含了它的样子）？

\documentclass[14pt]{article}

\usepackage[letterpaper,bindingoffset=0.2in,%
            left=1in,right=1in,top=1in,bottom=1in,%
            footskip=.25in]{geometry}
\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage[makeroom]{cancel}
\usepackage{tabularx}
\usepackage{xcolor}
\usepackage{hyperref}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usetikzlibrary{calc}

\begin{document}

\begin{tikzpicture}
        \begin{axis}[
                xtick distance=10,
                ytick distance=10,
                xmin=-0.0,xmax=144,
                ymin=-0.0,ymax=144,
                grid=both,
                grid style={line width=.1pt, draw=gray!10},
                major grid style={line width=.2pt,draw=gray!50},
                axis lines=middle,
                minor tick num=5,
                enlargelimits={abs=0.5},
                axis line style={latex-latex},
                ticklabel style={font=\tiny,fill=white},
                xlabel style={at={(ticklabel* cs:1)},anchor=north west},
                ylabel style={at={(ticklabel* cs:1)},anchor=south west}
            ]
            
        \draw (axis cs: 70, 70) circle [radius=10];
            
    \end{axis}
\end{tikzpicture}

\end{document}

如果您将width和height键设置为相同的值，您将获得所需的圆圈：

\documentclass{article}

\usepackage{pgfplots}

\begin{document}

\begin{tikzpicture}
        \begin{axis}[
                width=\textwidth,
                height=\textwidth,
                xtick distance=10,
                ytick distance=10,
                xmin=-0.0,xmax=144,
                ymin=-0.0,ymax=144,
                grid=both,
                grid style={line width=.1pt, draw=gray!10},
                major grid style={line width=.2pt,draw=gray!50},
                axis lines=middle,
                minor tick num=5,
                enlargelimits={abs=0.5},
                axis line style={latex-latex},
                ticklabel style={font=\tiny,fill=white},
                xlabel style={at={(ticklabel* cs:1)},anchor=north west},
                ylabel style={at={(ticklabel* cs:1)},anchor=south west}
            ]
            
        \draw (axis cs: 70, 70) circle [radius=10];
            
    \end{axis}
\end{tikzpicture}


\end{document}
