(In the future you're probably better off asking questions to the mailing list as a whole, since I can't promise timely (or even eventual) answers :-)
To label the center of each triangle, I believe the following will work (or is very close): this is written in script terms but obviously can be applied to the visual program editor. c = Extract(fieldoftriangles, "connections"); num = Inquire(c,"items"); trinums = Enumerate(start=0, delta = 1, count=num); //this just makes a list 0,1,2,3,......, num-1 trinums = Options(trinums,"dep", "connections"); //this adds dx-necessary meta-data; that these are 1:1 with connections output = Replace(trinums, c, NULL, "data"); // now you have as the data component, the index of the triangle labels = AutoGlyph(output,"text"); //this should make labels at the center of each triangle As for the vectors on the edges, unless you already have the positions of the center of the edges, this is going to be difficult. You might try this one on the forum. Donna _________________________________ Donna L. Gresh, Ph.D. Visual Analysis Group IBM T.J. Watson Research Center (914) 784-5049 [EMAIL PROTECTED]
