I hear you Martin, and I agree with you. We need more control over
our plots sometimes.

It dawned on me that we may not need *more* keywords to PLOT. Rather,
there should be a simple way to piece together a plot from simple
primitives. AXIS is a good start be we need other primitives to
establish coordinate systems and perform data scaling. Instead of
shoehorning more stuff into a monolithic plot command, it should be
easier to compose our own plot from simple elements. *Then*, in the
simple elements we can add these extra features.

In any case, I don't think it matters. RSI probably considers direct
graphics to be the wave of the past.
