2013-09-21 12:39:43 -0600 asked a question canvas3d plot does not change.

I am plotting with show(plt, viewer="canvas3d"). It works the first time, but I always get the same plot no matter how I change what goes into the plt variable. This does not happen when I plot with viewer="jmol".

How do I get canvas3d to refresh its plot?

2013-08-17 13:43:13 -0600 asked a question 3d Plotting not working when using server pool

I have the following line in my ~/.profile:

nohup sage -c "notebook(secure=True, interface='', directory='./sage_notebook.sagenb', timeout=3600, server_pool=['sage%d@localhost'%i for i in range(10)], ulimit='-u 100 -t 36000 -v 500000', automatic_login=False)" > /dev/null 2>&1 &

Ever since I started using the server pool, 3d plots will not show up. I get this error:

script ERROR: script ERROR: io error reading
/home/aeftimia/sage_notebook.sagenb/home/__store__/6/66/662/662c/aeftimi\
a/9/cells/509/sage0-size500-31677462.jmol.zip|SCRIPT:

a/9/cells/509/sage0-size500-31677462.jmol.zip (Permission denied)

I found what seems to be an active ticket with this issue here.

Here are my questions:

  • Is there no workaround for this?
  • Are the developers working on solving the problem?
  • When might there be a solution?

I would like to be able to use a server pool for extra security, but I hate to give up 3d plotting.

2013-08-02 08:01:39 -0600 answered a question Graphics are plotted on the wrong X11 display

It turns out that this was caused by setting SAGE_PATH to python's site-packages.

In hindsight, I realize this probably overwrote Sage's built in graphics libraries and caused the graphs to be plotted from the computer that started sage.

I set up a sage server by adding the following line to my ~/.profile:

nohup sage -c "notebook(interface='', secure=True, automatic_login=False, directory='./sage_notebook.sagenb')" >/dev/null 2>&1 &

I run my sage server from an Ubuntu desktop.

When I login and try to plot graphics from my laptop, the figures appear on my desktop screen.

I tried looking for solutions to this online, but I could not find anything.
