Hi, This is from the documentation of the plot method of the Digraph class: sage: T = list(graphs.trees(7)) sage: t = T[3] sage: t.plot(heights={0:[0], 1:[4,5,1], 2:[2], 3:[3,6]}) The result (on SMC, and I think it used to be the same on my local sage) is not what I expected at all: perhaps I

I can't say what is wrong either, but have you checked the browser console for any error messages? On a related note I am in the process of upgrading to new IPython/Jupiter (see develop branch on github) which may solve some issues as a side effect (or at least make it more clear what is going

[sage-support] Help needed with getting PARI/GP residue fields in Sage finite field form

For a number field N I am trying to factor an integral prime p in a p-maximal order Op. In the end I would like a map from the quotient of the p-maximal order Op/P (for P|p) to some finite field in Sage's standard finite field form, but I can't quite figure out how to do it. Firstly, Sage
