I think we all agree that underscore methods on classes that are private.
What this thread is about are module globals (like class names, constants),
that are not imported by default. I don't see may people using underscore
names for these. I certainly don't do it, and I can point you at lots of

Well, the reason for that is that
graphs.PetersenGraph().show(method="js") is not really a plot. Maybe
it also makes sense for Posets, by the way.

Hi
There is a 6.7 in the dev PPA, testers welcome. We've already deployed this
on campus, but is a homogeneous infrastructure.
sudo apt-add-repository -y ppa:aims/sagemath-dev
sudo apt-get update
sudo apt-get install sagemath-upstream-binary
sage -notebook
To revert, in case of problems:

Hi,
Working perfectly in Linux Mint 17, co-existing with IPython, IJulia and
friends without any issues. I updated from the version in the main ppa
instead of installing, though.
Thank you so much,

Good news. I remember a time when it would have ignored the parameter,
and plotted the usual thing :-P

I believe that the problem is in the absence of image fonts, not the JS

The thing is: we actually need this specific implementation which is much
quicker for what we're doing. So I'm going to look closer at the object and
probably open a ticket to allow for such basic operation.
