- 
plotimplicit(f(x,y),x,y) draws the graphic representation of the
curve defined by the implicit equation f(x,y)=0 when x (resp. y) 
is in WX-, WX+ (resp. in WY-, WY+) defined by cfg, 
- plotimplicit(f(x,y),x=0..1,y=-1..1) draws the graphic 
representation of the curve defined by the implicit equation f(x,y)=0 
when 0≤ x ≤ 1 and −1≤ y ≤ 1
 
It is possible to add two arguments to specify the discretization
steps for x 
and y with xstep=... and ystep=....
