Some .spkg files are just tar files, not bzip2'd, right? -Keshav Join us in #sagemath on irc.freenode.net ! -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org

The infinite loop is indeed stopped, further calculations are indeed run, and the further calculation output is put into the database, so everything seems okay on the server end, but somehow the further output isn't making it back to the browser.

I was told to set the ticket to Positive Review, as it catches Jeroen's eye.

[sage-devel] problems in inheriting Graphics() class
Hi all,
First of all what I am trying to do: I am trying to make loglog plots,
semilog plots, etc in Sage. I know of #4529, but it is not really helpful.
There are two ways I realized I can go about doing what I want:
1. Use matplotlib directly, but then I can't interface with Sage properly.
For example, the following works in the notebook and the image gets
displayed:
import matplotlib.pylab as Pyl
Pyl.loglog(range(1,10), map(lambda i: 10^-i, range(1, 10)), 'r+',
label='loglog')
Pyl.legend()
Pyl.savefig('./sage0.png')
The downside is that the syntax is matlab syntax and is different from the
one in Sage. Also, I would like to manipulate the graphics objects as
easily as in Sage.
2. Modify Sage.
I made a LogGraphics() class and after looking at the sources in plot and
the ticket #4529, I feel I need to redefine matplotlib() so that I can make
loglog plots, semilog plots, etc such that I still can work from the
notebook. Also, if I do it with Sage, then I can "add" graphics easily.
Problem I am facing. I have the following two lines in the beginning of my
file:
from sage.all import * # Just get things working for now
class LogGraphics(Graphics):
I don't define __init__(), the only things defined in LogGraphics are
__add__(), and matplotlib() where I have removed a lot of stuff on ticks,
since I don't want Sage to mess with the ticks. On running the program I
get this Attribute error:
AttributeError: 'LogGraphics' object has no attribute
'_LogGraphics__show_axes'
If I copy the __init__() from Graphics to LogGraphics then this error goes
away and I instead get another error:
AttributeError: 'LogGraphics' object has no attribute '_Graphics__objects'
So now I am at a loss. I don't want to start reimplementing every function
that is there in Graphics(). How do I make LogGraphics inherit Graphics()
properly?
NB: I am quite new to OOP, so I might be understanding some things wrong :)
