Why not draw the match as a picture first, then rotate and shift that
picture?
Also, if you use a local scale unit, it will be easier to stach the
matches together by merely applying a factor in match units.

i Henri,
Thank you for your answer. The idea is to make the graph as an attachment. I
converted to Metapost but the road is still long!
The code is from percusse on StackExchange. As you can see, there is a
problem with the ellipse. How do I fix this ?
