Bonjour à tous,
I hope I'm not too much out of topic, but I'm trying
to put a metapost figure in a context file.
I use a separate file for the figure to keep it
independant, (and to avoid cumul of problems :-)
The objectif is to build a graph by positionning some
node (for now, it is just a circle)
connecting them bu some ncarc connector (using metaObj)
and the put label onto these arc.
I know that one can do that using tree or matrix mataObj
feature, but I'd want to be flexible on the node positions,
Thank you very much for any help!

%%% START SAMPLE %%%%%%%%%%%%%%%%%%%%%%%
input mp-tool ; % some initializations and auxiliary macros

input metaobj.mp ; % suffixe non indispensable ?
beginfig(1) ;
numeric u; u=1cm;
z0=(0u,2u);
z1=(3u,4u);

% ...
% I'll have to create my one metaObj (later)
% newCircle.a1("") "circmargin(0.3u)";
% label(btex $x^2$ etex, z1);
newCircle.a0(btex 0 etex) "circmargin(0.1u)";
newCircle.a1(btex 1 etex) "circmargin(0.1u)";
newCircle.a2(btex 2 etex) "circmargin(0.1u)";
a0.c = z0;
a1.c = z1;
a2.c = z2;
% Question: how can I put a label on this arc???
ncarc(a0)(a1) "name(nc01)";
% The following doesn't work !
% ObjLabel.nc01(btex 0 etex) "labpos(0.75)",
% "labdir(top)";
drawObj(a0,a1,a2,a3,a4,a5,a6);
endfig ;
end .
