Yes, it is true that they are arbitrary in the sense that maybe tweaking them a little this way or that might give 'better' results in certain cases, but they are there as a result of a lot of 'testing' (read: making tons of plots) and taking the best values that 'in most cases' gives visually useful and good looking plots.

Thanks for bringing this up and working on it ... so maybe the best possible way to 'fix' this problem is to expose everything single possible parameter to the user (with given defaults of course), and then in most cases plots would look nice, but for making very exact plots, a user has the option to do a lot of tweaking.

I'm considering doing a semi-major clean up of the plotting functionality so please jot down improvements that you (or anyone) think could be made.
