So right now I have something like this:
As you can see, the xticks on the second (smaller) plot are a complete mess. Is it possible to just show 3 values (the first, midpoint and last ones)?
Secondly, is it possible to place something like a ~ or // break symbol at the beginning of the smaller plot, as it just shows the last 10 values of the bigger plot?
If I understand correctly what do you mean by "shift", you can use the x expr and y expr options like this:
\documentclass{article}
\usepackage{pgfplots,filecontents}
\pgfplotsset{compat=newest}
\begin{filecontents}{data.dat}
1 2
2 4
3 6
4 8
5 10
\end{filecontents}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
width=\textwidth,
height=8cm,
xlabel={$t~[s]$},
ylabel={$u$},
legend entries={a,b},
enlarge x limits=false
]
\addplot table [x expr=\thisrowno{0}-10,y expr=\thisrowno{1}+5] {data.dat};
\end{axis}
\end{tikzpicture}
\end{document}
tikz can do this:
\documentclass[tikz,border=5]{standalone}
\begin{document}
\begin{tikzpicture}
\foreach \x in {0,...,5}{
\draw (\x,0.2) -- (\x,-0.2)node[below]{\x};
}
\draw[fill=magenta!40] (3.5,0) circle (3pt)node[above=0.2cm,anchor=south]{3.5};
\node[anchor=north] at (0,-0.6) {Start};
\node[anchor=north] at (5,-0.6) {End};
\end{tikzpicture}
\end{document}

To add axis discontinuity use axis option
axis x discontinuity=crunch|parallel|none(only one of the three, your choice) as explained inpgfplotsmanual at page 123.With option
xtickof theaxisenvironment you can choose what ticks to show, just type them inside brackets inxtick={}and separate them with,.
