I can understand why having an adaptive approach which uses random
numbers is more robust than "dx=(xmax-xmin)/100" etc. What I don't
understand is why the default behaviour isn't to use a set seed so
that the result of plotting calls would be reproducible.
If there's a real difference between using one seed and the next, in
that sometimes it produces a good plot and sometimes it doesn't, then
aren't you going to need to control the seed anyway to get the good
plot back? And if there isn't a real difference, then why not simply
pick one and get all the benefits of the adaptive approach while
preserving reproducibility?
+1 to having a default random seed that doesn't change each plot (maybe
a module-level variable in the plot module, like RANDOM_SEED, so that a
user can change the seed if they want).
