Use it to draw a function described by a "equation" [z=F(x)] (Z-X plane) The example done here generate a parabol.
Needs to be defined :
F = variable used in the function,
X = initial value of x,
Nb = Number of step,
Z = function express with x
ZZ = function express with xx


 import FreeCAD, FreeCADGui, Part
 import math
 F=800
 X=-500
 Nb=10
 Step=1000/Nb
 Y=0
 for I in range(Nb):
 	XX=X+Step 
 	Z=X*X/(4*F)
 	ZZ=XX*XX/(4*F)
 	if I==0:
 		print "Le test est vrai !"
 		nomme=Part.makeLine((X,Y,Z),(XX,Y,ZZ))
 		WWire=Part.Wire([nomme])
 	else :
 		print "Le test est 2 !"
 		nomme=Part.makeLine((X,Y,Z),(XX,Y,ZZ))		
 		WWire=Part.Wire([WWire,nomme])
 	X=XX
