Making an axis break

Question

so I'm working on a graph in pgfplots and in my data there is are a few outliers as you can see here

so I was wondering how can I break the y axis as to enlarge the difference between the other 3 values. similar to this

Here my code so far

    \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}

Hi, welcome. You could use a groupplot as in https://tex.stackexchange.com/a/62778/ Edit: see also https://tex.stackexchange.com/q/359878/ — Torbjørn T., Apr 18 '20 at 20:45
Welcome! You will get better and more timely help if you post a complete minimal working example. I guess besides you not many users will have the data files you are using. You can use coordinate transformations to get the effect. (@TorbjørnT. Are you sure this post works also if the individual plots go in both or all three ranges?) — , Apr 18 '20 at 20:45
@Schrödinger'scat On second thought, no. Didn't really think that one through ... (Abdelsalam: ignore at least my first link.) — Torbjørn T., Apr 18 '20 at 20:51
Just looking at the plot I think there is a good chance that ymode=log will do the trick. — , Apr 18 '20 at 20:55

This is how you can do it to line chart.

Then download the generated PDF file and upload it to the original location of the main text file. And there you can add following code to generate high-quality image:

\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*}

Finally you can see a continuous curve.
