I'm not really all that crazy about the big array either.
But I think there is some value in collecting plot options in one place.
There exists a function named defstruct (invented by RJF a
few years ago and imported by me sometime later) which might
be helpful here. We can define a plot options structure, e.g.
defstruct (plot_options1 (foo=1, bar=2, baz=[x, y]));
my_options : new (plot_options1);
my_options at foo;
=> 1
my_options at baz;
=> [x, y]
my_options at bar : 7;
my_options;
=> plot_options1(foo = 1, bar = 7, baz = [x, y])
A plotting function could observe a global plot options structure
or accept a plot options structure as an argument (and perhaps
accept isolated options as well). Something to consider.
