问题

我想在和x轴上添加轴不连续性y，但这样做（即使只有一个轴）也会将我的整个图向右移动。

图片）

无轴不连续性

该图没有明确放置轴不连续标记，因此没有问题。

由于轴线不连续

该图明确放置了轴不连续标记，因此其放置很混乱。

答案1

您的图中有几个奇怪的内容。造成问题的主要原因是将其与图中的 y 值domain={0:\pgfkeysvalueof{/pgfplots/xmax}},结合使用。x

当 PGFPlot 改变其计算边界框的方式以包含紧缩因素时，它还包括超出轴的长线性图。

\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
xmin=40, xmax=57,
ymin=20, ymax=32,
axis lines=left,
axis y discontinuity=crunch,
declare function={supply(\P)=2.05*\P;},
]
\addplot[
blue, thick,
domain={\pgfkeysvalueof{/pgfplots/ymin}:\pgfkeysvalueof{/pgfplots/ymax}},
] ({supply(x)}, x);
\end{axis}
\end{tikzpicture}
\end{document}

具有紧密边界框的图形

答案2

回答

在查阅了相关pgfplots文档之后，我发现了似乎可以完成这项工作的tikz风格。trim axis left

/tikz/trim axis left

一种有价值的风格trim left=(current axis.south west)。

需要将样式作为参数提供给\begin{tikzpicture}[trim axis left]。它要求图片中至少有一个PGFPLOTS环境。效果是修剪最后一个轴的锚点左侧的所有内容south west（即左轴边界左侧的所有内容）。

   -PGFPLOTS手动的
