The following works nice:
G=Graph({0:[1,2],1:[2,3],2:[4]})
G.show()
But the following produces a wrong drawing
H=DiGraph({0:[1,2],1:[2,3],2:[4]})
H.show()
However, H.show3d() works fine
Now, there is another problem:
Say, I want to define a multigraph with selfloops, and edge labels..
One way
Hi all !
Is there a simple way to plot a graph with more than 1 edge going from
a given vertice to another, as in the konigsberg graph ?

Thanks !

This is one way:
sage: def xt(t): return t
sage: def yt(t): return 1
sage: parametric_plot((xt,yt), -2, 2)

I *conjecture* (and definitely could be wrong) that your problem is related
to the issue that Sage can plot symbolic functions but constants (rather,

This is an attempt to ask my previous question more clearly :-)
I'm looking for a work-around for the situation where I would normally
call parametric_plot (or plot, for that matter) with a function, and in
some particular case that function turns out to evaluate to a constant.
For example:

Thanks. In view of your reply, I deleted Sage, re-booted, and then re-
installed (now in the main Applications folder, rather than in my
personal users Application folder). Now Maxima

Hello,
I am installing Sage-3.1.1 on Arch linux with enabled PBUILD. However,
the installation fails with following errors:

I noticed that the binaries for Mac only include sage-3.1.1-osx10.5-
intel-i386-Darwin.dmg. Does this work for osx10.4, too? If so, it
would be good to make this cl

Both Maple and Mathematica give wrong answers to the following sum,
Sum[Binomial[n, k]/Binomial[2 n, k]/k! (2 x)^k, {k, 0, n}]
I tried to find a way to calculate it in SAGE, but couldn't find symbolic
sums in the documentation. Is Maxima supposed to be used directly?
