我正在制作一个图表，pgfplots我的数据中有一些异常值，正如你在这里看到的
所以我想知道如何打破 y 轴以扩大其他 3 个值之间的差异。类似于此
这是我迄今为止的代码
\begin{tikzpicture}
\begin{axis} [ylabel=$T_{pdr}/s$,xlabel=Transition$/ps$,legend pos=outer north east]
\addlegendentry{$\mathrm{C}_{inv}$}
\addplot table [x=Transition,y=tpdr,col sep = tab] {./data/complex/size1/cin1.csv};
\addlegendentry{$2\mathrm{C}_{inv}$}
\addplot table [x=Transition,y=tpdr,col sep = tab] {./data/complex/size1/cin2.csv};
\addlegendentry{$4\mathrm{C}_{inv}$}
\addplot table [x=Transition,y=tpdr,col sep = tab] {./data/complex/size1/cin4.csv};
\addlegendentry{$8\mathrm{C}_{inv}$}
\addplot table [x=Transition,y=tpdr,col sep = tab] {./data/complex/size1/cin8.csv};
\end{axis}
\end{tikzpicture}
答案1
这就是如何对折线图进行操作的方法。

然后下载生成的 PDF 文件并将其上传到主文本文件的原始位置。在那里您可以添加以下代码来生成高质量的图像：
\begin{figure*}
\center
\includegraphics[scale=0.8, trim={3cm 16.5cm 4.5cm 2.2cm},clip]{Generated_Plot1.pdf }
% trim from right edge
%\includegraphics[trim={0 0 5cm 0},clip]{SMOTE.pdf}
\caption{\label{schema}Caption 1}
\label{fig}
\end{figure*}
最后你就可以看到一条连续的曲线。
