points->coords[0]: x
points->coords[1]: y

basically the even index is the x co-ord for the pair
and the odd one is the y.

The complete set of arguments are listed under the corresponding item.
Some other items define their own,
for example gnome-canvas-pixbuf has "width_set" and "height_set" that
nothing else has.
so it depends on the type of the item you want to create.
