First of all "A Happy New Year to everyone!"
Ok, sage-2.9.1-linux-ubuntu-32bit-i686-Linux on Ubuntu 7.10 machine I
get a plot for this:
sage: maxima.plot2d('[-7.5/-0.5*(x-0.5)+8,-7.5/7.5*(x-0.5)+8]','[x,
0,8]', '[y, 0, 8],[ylabel,"y"],[gnuplot_preamble, "set grid xtics
ytics"],[legend,false]')

After executing the following commands in Sage:
QQi.=QQ.extension([x^2+1]);
R.=MPolynomialRing(QQi,order='lex')
T1_Pxxx=3*a^2*b+(1-a)^2*(1-b)-f0
T1_Pxxy=3*(1-a)^2*b+3*a^2*(1-b)+6*a^2*b-f2
T1_Pxyz=6*(1-a)*a*b+6*a*(1-a)*b+6*a^2*(1-b)+6*a^2*b-f1
T1_Pyxx=3*(1-a)*a*b+3*a*(1-a)*(1-b)+6*a^2*b-(1-f0-f1-f

I'm not sure that you mean by "...and the function documentation...".
