add titles above distinct parts of graph

Hello!

Does anyone know how to add titles above two parts of a graph and maybe also include hooks like the ones shown in the image I have appended? I simply want the lila hooks and the titles "ph2","ph3" but I have no idea how this could be done. To get the rest of the image i used the following code:

plot(tpoints_final, howmany_final);
set(gca, 'YLim', [1, alltrials]);
until = ceil(tpoints_final(end));
set(gca, 'XLim', [0, until]);
hold on
plot(xlim, [1 1]*45, '--b');

Thanks on advance!!
