I try to draw with asymptote one arrow between two terms of an equation
for example
pair position=(1,1);
label("$x^2+x+1=a+b+c$", position);
how to draw an arrow from $x^2$ to $a$ ? Or is there a way to calculate the position of a term ?
pstricks and tikz allow to locate a portion of an equation like this code shown by this link
I would like to do it with asymptote.
Can someone help me ?
Thanks
(of course I can hardcode the positions but my equation is more complicated, and does not support any modification)
