Hello,
Could you please advice the way to plot three-dimensional array?
Something like plot3d or counter_plot, but in case the data are
already calculated in array and there is no way to call f(x,y).
Best regards,
Eugene.

Hello,
I've got two computers with archlinux (i686 and x86_64 versions) and
on both machines there is same problem installing sage:
$make
File "/home/ajunta/Binary/sage-4.3-linux-Ubuntu_9.10-x86_64-Linux/
local/lib/python2.6/site-packages/sage/interfaces/gap.py", line 362,
in _start
ra
Thanks for the advice, I had some problems building previous version
of sage, and like that one - it solved by building sage from source. I
guess building from source is the best way to avoid many problems.

Hi!
I've got a few functions like this:
f1(x,y)=sin(x)+cos(y)
f2(x,y)=sin(y)+cos(x)
and I need to plot counter graphics like:
contour_plot(lambda x,y:f1(x,y),(x,0,3),(y,0,14))+contour_plot(lambda
x,y:f2(x,y),(x,3,6),(y,0,14))
can i do this easily using piecewise function?
g=Piecewise([ [(0,3)
Could you suggest one?
I've seen this, but i think it's not a good solution..
contour_plot(lambda x,y: data[int(x)][int(y)],(x,0,len(data)-1),(y,
0,len(data[0])-1))

Hi!
I've got an error in rendering Unicode characters in plots:
plot(sin(x), (x,0, 10) , axes_labels=['Cyrillic text here','y'])
'y' lable is ok, but text on 'x' lable renders as sequence of
rectangles.. is it missing fonts or something like that?

Hello!
There is plot:
p=plot(sin,0,2*pi)
How to add grid lines to this plot?

Hi!
I want to save my plot using notebook:
plot(sin,0,4).save('foo.png')
this code saves my plot, but also calls show method (or something like
that) and I have plot in output. Is it possible only to save plot,
without any output at all?

Hi all!
I am using sage from time to time for a year in education.
Unfortunately, I couldn't find default functions to do some
operations, so I wrote my own functions. For now here are just a few
functions, but I believe in time I'll describe them all.
I've placed them in Google Code project page
Hello!
I am using Sage with Notebooks for some time, and my .sage directory
now is 129 Mb. I believe it is impossible for me to write so much code
(text), that means most of this space comes from notebook cache
(images, for example). Is there some easy way to remove cache?
Best regards.

My temporary solution - removing all *.sobj, *.gif, *.png, *.zip files
and all "snapshots" directories. Now .sage direcotory is 13 Mb only!
Also, I have found for myself important tip: while using DATA
directory manually for saving objects (*.sobj files) no one will
manage it content for you, and
P.S. It is also ok to remove "dap" directory content.
