Hello,
I've recently been creating some diagrams of trees with sage and have
run into some difficulties getting the graphs to look decent. I have
frequently run into issues with labels of vertices overlapping. Is
there anyway to enforce a distance between vertices or otherwise
ensure that the
The best way is probably to use mpmath.mpmath_to_sage(). Just note
that you have to provide the desired precision as well as the number
to convert.

Dear
xs was the list of x coordinates which I created with range

It saves a graph with labeled axes but no plot. I don't understand the error
messages (either for your code or for mine) produced though.

I have recently been using save_session a bit, and I uncovered what I
believe is a bug. If the worksheet of the session that I'm trying to
save contains a cython function, then load_session chokes. For
example:
var1 = 1
var2 = 2
var3 = srange(1,1)
var4 = range(1,3000)
var5 = 1234.123456

requested, but overall, I didn't see a single major deviation
(although that obviously isn't concrete proof).

When I timed these functions over 1 through 700 at 53 bits
I have recently been experimenting with converting some simple python
functions that I have made into cython. I have been quite impressed by
how simple it is for the massive speed increases that I have seen.
However, one thing that is mildly annoying at times is the limitation
to double precision
I have noticed recently that when evaluating the EI function at any
number over 20, it adds 2pi i, which shouldn't be there. After looking
at the code it appears that it uses scipy, so the error is probably
there. However, when looking for alternatives, I found the

someone can fill out a trac

Thanks for your responses. The reason that I didn't install the extra
Tex fonts explicitly is because I thought that the jsmath-fonts
package contained them already, however, I'll try and explicitly
download them into that directory.

After a little more searching, it appears that I should use a Pseudo
tty( right?). However, the programming guide gives no information on
how to actually do this. Any help would be greatly appreciated
(copying and pasting input and output is less than ideal).

Is there any way for SAGE to calculate Li(x) (logarithmic integral)
for complex inputs?
