[sage-support] more control over plots
Hello, I've tried looking at all the plot options in the documentation, but I can't find how to do the following. Maybe someone can help... * control over the scaling of the y-axis. I can choose xmin and xmax, but the range of the y-axis is always chosen automatically. * control over where the y-axis is located. It sometimes just ends up right smack in the middle of the graph and looks dumb, I'd prefer for it to be on the left. * turning off the numbers on the axes. I'd like the axes to show, but not the values. * having a light gray grid displayed in the background of a plot Cheers, Maike --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Re: more control over plots
Hi Jason,
Thanks for the help! Which parameter is it that tells the axis to be
on the left? My example is:
rsa = line([(2000,952),(2005,1149),(2010,1369),(2015,1613),(2020,1881),
(2025,2174),(2030,2493),(2035,2840),(2040,3214)],rgbcolor=green)
ecc = line([(2000,132),(2005,139),(2010,146),(2015,154),(2020,161),
(2025,169),(2030,176),(2035,184),(2040,191)],rgbcolor=red)
(rsa+ecc).save('bild.png',xmin=2000,xmax=2040,axes_labels=['year','key
length in bits'],figsize=5)
Here I'd like the axis to be on the left. Can you tell me how to do
this here? Thanks!
Maike

For these two, use the ymin and ymax options in show when you show
the plot. Something like:
sage: plot(sin(x), (x, -pi, pi)).show(ymin=-1, ymax=3)
Sorry, I misread your second point. The following example puts the
y-axis on the left:
sage: plot(sin(x), (x, 0, pi)).show(ymin=-1,ymax=-3)
Does that help?
Jason

[sage-support] Links between worksheets
Hi all, I can have a link on one worksheet to another worksheet (e.g. http://localhost:8000/home/user/12/), but this includes the number that sage internally gives that worksheet (here: 12). Now if I upload these worksheets to another server, they are assigned different numbers and the links don't work properly anymore. Is there a any other way of linking in a more stable way, e.g. using the title of a worksheet? Also, can I have a link that goes to a certain place within a worksheet?

[sage-support] Secure Sage Server
We'd like to set up a sage server allowing different users to see, copy and edit our published worksheets. However, this allows users to execute arbitrary system calls, e.g. os.popen(ps auxw).read() The formatting of the output is not perfect, but still, this is a problem! I'd be grateful for any suggestions on how to set up a SECURE sage server. If this has been covered elsewhere, just post the link... Thanks!

[sage-support] Re: Suggestions for the notebook
Okay that's right. But still, #auto doesn't work together with %hide or %latex, no matter which order I put these commands in, and I need this feature for my %latex cells, because they're the ones not being executed when I start up a worksheet.

There was a bug in Sage 3.1.1 that caused any associated files or images with a cell (such as plots or the output of %latex cells) to be deleted when the worksheet was closed. If this is the reason why you want to use the auto cells, you should upgrade to Sage 3.1.2 since I fixed this bug in it. This should alleviate some of your problems. --Mike --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Okay, here's another big problem that seems to have come with version 3.1.1: Edit a copy doesn't work any more on published worksheets! Sage makes a copy, but I can't edit it. This is a big problem, as we're working with several users. Please help! Thanks.

[sage-support] Upgrade to version 3.1.1
Hello, I just upgraded from 3.0.5 to version 3.1.1 and several things aren't working any more: 1. sliders aren't showing when used with the interact-functionality. It doesn't work the way it used to in the older version, and it doesn't work when I copy examples directly from the documentation. There's just the name of the variable, but no slider next to it. What can I do?? 2. Without changing any of the code, I get a new error message that wasn't there before, and it doesn't tell me the line of code where something went wrong. Since the code is pretty long, maybe someone can tell me what kind of error I have to look for when I see this: ValueError: invalid literal for int() with base 10: 'NaN' 3. Syntax on arrows has changed. Before I gave the starting and ending point of the arrow, now you have to give the starting point and the difference between the starting and ending points (something like (3,4) meaning 3 to the right, 4 up). However, the documentation still explains it the old way and it took me a while to figure it out. Thanks for any help with the first two problems!

[sage-support] including images
Hi, I'd like to include an .eps graphic in my sage-notebook output. neither the latex \includegraphics command nor the html img tag seem to work. Which command can I use, and where should I save the .eps file? I've also tried to find the files created by the sage .save(...) function (hoping to be able to put my file in the same place), but I wasn't able to locate them. Where does Sage put those??

[sage-support] Re: AttributeErrors in EllipticCurve classes
John, Hello again :-) While you're working on more elliptic curves stuff, what I could use is the following: I'd like to define points on curves by just providing the x-coordinate (and maybe an indicator of which of the possible two y-coordinates I want). When I do something like E = EllipticCurve(RR,[a,b]) P = E([xP,sqrt(xP^3+a*xP+b)]) it doesn't always work. Or is there a way of doing this already?

[sage-support] using latex packages
Hello again,
is there any way to use latex packages within sage? I'd like to write
a german text, and that will be a pain if
%latex
\usepackage{ngerman}
doen't work. Maybe I first have to install the package somewhere??

[sage-support] Re: using latex packages
Hi William, That sounds great to me. As long as it'll allow me to load the ngerman package in the notebook version of Sage, that'll do. Thanks! Maike P.S. And thanks Stan for the hint! I didn't know sagetex. As I'm using the notebook to combine latex typesetting with the interact functionality of Sage, it's probably not the best idea.

[sage-support] latex-hyperlinks not working
Hello,
I'm writing some latex-text in Sage and am trying to put a web-link
into it. Usually in latex the commands \htmladdnormallink and
\htmladdimg do the job. Here however that's not working.
%latex
\htmladdnormallink{Google}{http://www.google.de}
Does anyone know which command will work?
Thanks!
