[sage-support] Re: plotting ln(x) graph on sagemath
syntax should be show(P) or P but not print P which gives you your result Le samedi 17 septembre 2016 23:13:05 UTC+2, Anoz a écrit : > > I'm trying to plot the graph ln(1+x/1-x) how do I do this on sagemath , I > just need the correct syntax. > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Maybe fist write %matplotlib inline Sometimes I got the same problem I do it first with python2 kernel and after I do it with sagemath again Le samedi 17 septembre 2016 23:13:05 UTC+2, Anoz a écrit : > > I'm trying to plot the graph ln(1+x/1-x) how do I do this on sagemath , I > just need the correct syntax. > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

I installed sage at /home/jack/Tools
One clue might be the initial message I get on initiating sage in a
terminal. It reads:
sys:1: RuntimeWarning: not adding directory '' to sys.path since everybody
can write to it.
I have no real clue, but I would start with
strace -e file ./sage 2> log-f
then write
plot(sin)
or something similar and then quit Sage. After that
fgrep tmp_ log-f
shows
open(".../.sage/temp/j-op7010/12072/tmp_n3Sn3X.png", ...) = 11
etc. and
fgrep EACCESS log-f
finds nothing.

Untrusted users could put files in this directory which might then be imported by your Python code.
