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。

无轴不连续性
由于轴线不连续
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{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}

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
