Description
Use it to draw a function described by a "equation" [z=F(x)] (Z-X plane) The example done here generate a parabol. Has no dialog. 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
Script
Macro_Draw_2D_Function.FCMacro
# 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

for I in range(Nb):
