Replace random values by hard-coded numbers in plot-types ...

... for the cases where we have only very few random numbers.
This makes the code a bit simpler, because we do not have to
seed. Also, a list of hard-coded numbers is slightly simpler to
grasp compared to a rng function. This is partly also in
anticipation of the switch to numpy's rng generator classes.
While conceptually superior, they are a bit more verbose and
introduce the additional local variable `rng` (IMHO this is the
benefit and the downside: It explicitly ties the rng state to
the local context -&gt; clarity. But OTOH the user is bothered
with this local state even if it's not important to them - like
in our examples.)
