Amazingly some very basic functionality for plotting hasn't yet been
implemented! In particular, there is nothing yet for setting the location
and labels of all tick marks on the x and y axes. This needs to be
implemented.

Sage. For example, I should have ticks that are rational multiples of e
as well.

be expanded to being a list (if symbolic expressions, then latexing them
can give the formatters), or a function.
These make lots of sense. It should be easy to check if the string is in
symbolic.constants or something (or even accept those as input), and then
of course one would have to check if there was a symbolic expression in
the list, and (possibly override) use tick_formatter appropriately. After
all, multiple_of_pi could be made generic to
multiple_of_symbolic_constant, and then we could make a dummy function to
input into FuncFormatter or something.
