Problem with plot

[Philippe Delavalade]

Hi.

I'm using sage-10.2 with linux (slint-15.0 based on slackware 15.0) on the
console.

When I run
p=plot(x^2); p
there is no graphics on the screen, just the line
Launched png viewer for Graphics object consisting of 1 graphics primitive

Is something missing in my configuration ?

Moreover, in help(plot), the command sphinx_plot is often used but on my
machine I obtain
NameError: name 'sphinx_plot' is not defined

Thanks for help.

Maybe : WorksForMe(TM) on Debian testing installed from source. How did you obtain your installation ?

Googling sagemath sphinx_plot leads you to the General conventions chapter of the Sage developer Guide, where it appears that this function is part of the Sphinx system of documentation (especially the mechanisms extracting viewable/printable documentation from Python docstrings).

This function appears to trigger the output of (some relevant form of) graphics in the desired documentation. Since help gives you a text form of the docstring, which does not have any useful form of graphics, what you get in the output is the (unexecuted) function call.

A complete explanation probably exists in the Sphinx documentation, which I’m currently too lazy to chase on the ‘Net…

HTH,

It's probably just a build error. I'd try something like

make sage_conf && make
