Don't get me wrong, but I think you mix up variables and 
parameters. The graph of f(a,b,c,d,e,f) would be a 
7-dimensional surface, depending from the 6 variables you'd 
like to use. Since humans usually see 3-dimensional, 
gnuplot only support 2 variables maximum: f(x,y) [or - when 
in parametric mode, ususally f(u,v)]. 

You may use unlimited much parameters within mathematical 
equations:
a=1
b=2
c= 3 
...
f(x,y) = a*x + b*y + c*x**2 + d*y**2 + e*x*y ...
