填充导致 tikz 图片在 beamer 中跳动

Question

我遇到了 tikz 图片跳跃的问题。当我添加填充时，图片会跳跃，如下例所示。有趣的是，这是我在 Mac 上遇到的问题，但在 Ubuntu 电脑上没有遇到。

\documentclass[10pt, aspectratio=169]{beamer}

  grid=none,
  }}

    \centering
    \tikzset{>=stealth}
   \begin{tikzpicture}[scale=\myscale] %%def \myscale
    \begin{axis}[
    axis equal,
    axis x line* = center,
    axis y line* = center,
    xmin=-0.05,xmax=1.05,

    scale=1.5,
    transform shape
    ]

  %% parameters
  \def \wtilde {0.25} %% phi(wtilde)=0
  \def \concav {2} %% phi has a power 1/concav
  \def \phimax {0.63} %% phi(1)=phimax

  \plot[name path=f1,thick, color = black, dotted, samples=100, domain=\wtilde:1] {\phimax * ( (x-\wtilde)/(1-    \wtilde) )^(1/\concav)};
  \plot[name path=X1,thick,opacity=0,samples=2,domain=\wtilde:1] {0};
  \plot[name path=X2,thick,opacity=0,samples=2,domain=0:\phimax] {1};

  \end{axis}

我无法重现您的问题。在您的文档中，两个框架中的设置可能不一致。为了避免可能出现的差异，我建议为两个图像定义通用轴选项：

\documentclass[10pt, aspectratio=169]{beamer}

% Theme stuff 
\usetheme{Warsaw}
% general packages
\usepackage{appendixnumberbeamer}
\usepackage{booktabs}
\usepackage{subcaption}

\usepgfplotslibrary{fillbetween}
\usetikzlibrary{arrows.meta}
\pgfplotsset{compat=1.18,
PLOT/.style={   % common definition of diaghram styles
    height=\textheight,
    axis lines = center,
    axis line style={-Stealth}, % arrows on the axis
    grid=none,

    axis equal,
    xmin=-0.05,xmax=1.05,
    ymin=-0.05 ,ymax=1.05,
    xlabel={},          % default put x on x-axis
    ylabel={},          % default put y on y-axis
    every axis plot post/.append style={thick}
            }}

% diagram
  \plot[thick, dotted, samples=100, domain=\wtilde:1]

% fill
  \addplot fill between[of=f1 and X1,
                        soft clip={domain=0:1},
                        every even segment/.style  = {black,opacity=1}
