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 :)
