Hi.Philippe:
You can use LabTalk function [winName!]Layer[n].axis.property to operate the axe's break, grid, and label.
For example:
Assurm you Origin workspace have graph "graph1",
use following function to make graph1's layer1 buttom Axe to show major out and minor in:
Input the command in to Labtalk console and press enter.
Graph1!layer1.x.ticks = 6
