can't find how to do the following. Maybe someone can help...

Hi Maike,
I found that the use of pylab allows a lot more control over your
plots. Example:
import pylab
x1 = srange(0,1.1,0.01)
d1 = [2*x+x^2 for x in x1]
d2 = [3*x+0.9*x^2 for x in x1]
title='Test plot'
pylab.clf() # clear the figure first
pylab.figure(1)
# plot some data and add a legend
I have a worksheet Getaltheorie in my Worksheet List. When i give
the command attach Getaltheorie (or attach 'Getaltheorie', or or
attach 'Getaltheorie.sage' or ...) in another worksheet, i get the
error message 'Error attaching /Users/jokr004/.sage/Getaltheorie --
file not found'. I'm sure I'm
Dear all,
When I upgraded to 3.1.2, I found that some of my plots generated
using pylab in the notebooks miss their bottom bits. It seems to be
related to the dpi setting. Example:
import pylab
x1 = srange(0,1.1,0.01)
d1 = [2*x+x^2 for x in x1]
pylab.clf() # clear the figure first
I can confirm this bug and opened

Since upgrading to 3.2.1, the following does not work any more:

Thanks for the help! Which parameter is it that tells the axis to be

I am brand new to this. I was wondering how to calculate mods while in
the sage notebook. I need to calculate 520622^430085 mod 998171. Does
anyone know how to type this into the command line. I keep getting a
syntax error. I have no idea how to do this because I am brand new to
sage. Thank you.
sage: 520622^430085 % 998171
897985
It is very much faster to do it more like this:
sage: R=Integers(998171)
sage: a=R(520622)
sage: a^430085
897985
The first way (I think) computes 520622^430085 as an integer and then
reduces, while the second way constructs the ring of integers mod
998171,

A more general question, how can I find out all the possible options
for a command, like show for example?
I've tried show.option? which doesn't seem to work.
