I am having problems with matplotlib, Sage plotting and, apparently,
backends. I have installed Sage 6.2 on my Mac Book Pro (system 10.6) (I
just upgraded from Sage 4.2). I have removed all copies of matplotlibrc
from my computer except for the file buried in Sage-6.2/.../mpl_data/. All
From earlier thread, either of two work-arounds worked for me in Sage 6.2:Work-around #1:sage: import matplotlibsage: matplotlib.use(‘agg’)sage: import matplotlib.pyplot as pltWork-around #2:rename ~/.matplotlib/matplotlibrc to .matplotlib/matplotlibrc.bakJim Clark-Original Message-

Hi, Jim,
Thanks for the reply. I tried your suggestions (below), but I am having
trouble running from a script, not the Sage or iPython interface for which
TKAgg works fine. As for the script trials I did, #1 doesn't work for
either pylab plot or D.show() (a Sage Graph plot). #2 is not
Hi all,
I've done some work in Java, HTML, CSS, JavaScript, ActionScript 3.0 and
recently Python.
I have a project I'm working on where I'd like to set up a very simple Sage
server, to function as follows: The server will receive Sage or Maxima
code, execute the code, and send back the
In bold : where you and I disagree
you : By m is represented by Q, I mean that there exists a vector v with*
integer* entries such that Q(v) = m
me : By m is* locally* represented by Q, I mean that there exists a vector
v with* rational* entries such that Q(v) = m
You want to use

Thank you Dominique,
I didn't realize that is_locally_represented_number() is defined to return
True if and only if m is locally represented by Q over the *rational* numbers.
(I misunderstood the documentation for the function.) In that case, you are
correct.
Is there a function in Sage that
I don't see what the issue is with the code below:
phinS=e^(i*n*pi*x/a);
phim=e^(-i*m*pi*x/a);
a=var('a');
assume(a 0);
n=1;
m=1;
integrate(phinS*phim,x,-a,a)
I get this undecipherable error:
Traceback (most recent call last):integrate(phinS*phim,x,-a,a)

This error is more concisely generated with:

A, that is the issue.
Thanks

2) I've noticed on the Sage Cell Server demo online that typing Maxima
code will result in every line being evaluated but Sage code only evaluates
the last line. For example,
integrate(1,x)
integrate(2,x)
In Sage code
