Greetings,
I've encountered a problem which I can't at the moment solve. Hopefully
the solution is either known or obvious to someone on this forum, but I
would appreciate any constructive input.
When I try to make a graph with the following:
p1=plot(delta.substitute(px=5,py=0,pz=1,R=1,h=10,w=1),(t,0,1))
p2=plot(diff(delta,t).substitute(px=5,py=0,pz=1,R=1,h=10,w=1),(t,0,1),color='red')
show(p1+p2,gridlines=True)
I get an error on the creation of the graphics object 'p2' stating the
object does not have a '_set_extra_kwds' attribute. The full traceback is
below.
Traceback (most recent call last):

This occurs on a worksheet that had no such error running on Fedora 20
(which I believe is running sagemath 6.1.1-6.fc20, but I'd have to go into
the office to double check). This error occurs on my ArchLinux system
running sagemath 6.7-2. I've seen from googling around that this may have
been a bug several years ago, so I'm guessing this is more likely a problem
of a missing dependency on my Arch system. Please let me know if there is
anymore information I can provide to help solve this problem.
Thanks,
C
