I'm an old Ada hobbyist who would like to plot some data from a
computation. What I want is scientific plots that are sort of the
opposite of industrial strength, in that small effort produces small
result but has no aspiration to scale.

The kind of data I'll be examining are similar to
--
type data is array (min..max) of float;
X, Y : data ;
--
circle (X, Y : out data) ;
-- makes (max-min+1) values satisfying
--       x**2 + y**2 = 1;
plot_curve(X, Y) ; -- syntax to suit
-- puts a figure that's sort-of round into a window

I've collected beaucoup graphics libraries over the years - (claw,
gwindows, jewl, win_io, windex, once upon a time a fairly immature
gtkada...)

But I'm not a devotee of U-I programming so I've never committed much
thinking to any of these.  I'm going to stay uninvolved with buttons,
callbacks and dialogs.  Instead, I just like to compute and plot
numeric
values.  I wish I could do that in a context that didn't make me learn
all that stuff I'm not using.

By way of comparison, I consider my need alongside the capabilities of
the R language environment.  Their plotting far exceeds my needs.  But
the R language is a sad homely thing alongside Ada.

So can I ask for a suggestion: which library would be simplest for me
to install and use for my task?

Good fortune in the new year to all
John
