    That's commonly called "broken axis" (this is why you couldn't find it by searching). Ther is no native possibility, but you can see https://tex.stackexchange.com/questions/283741/axis-break-in-pgfplots-same-scaling-for-the-two-plots (in y direction) or https://tex.stackexchange.com/questions/149081/collapse-range-in-x-axis-with-pgfplots-break-x-axis (along x) – Rmano Apr 23 '22 at 11:49

    @Rmano Given that this is at the start of the axis with no data to the left of the discontinuity, doesn't axis x discontinuity=crunch do exactly what the OP for? – Torbjørn T. Apr 23 '22 at 16:03
  • @TorbjørnT. I just discoved that option ;-) ... Thanks! – Rmano Apr 23 '22 at 18:31

You can use the axis x discontinuity option (as also suggested in the comments):

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
    thick,
    axis lines=left,
    axis x discontinuity=crunch,
    ticks=none,
    xmin=0.8,
    xmax=2.2,
    ymin=-0.2,
    ymax=1,
]
\addplot[thick,domain=1:2] {ln(x)};
\end{axis}
\end{tikzpicture}
\end{document}
