Hi,
These settings are not readable/writable via labtalk, I'm afraid that you will have to do this manually.
In case you really need to do this via Labtalk, I think you may use tick location/label from a dataset as a workaround. To do this you'll need to have a column of tick location data and probably another column of tick label, an example would be:
//Suppose you have column C as the tick location data and column D as corresponding tick labels (both in book1, sheet1) and want to change the tick labels of x axis
range ra=[Book1]Sheet1!col(C);
layer.x.TicksByData$=ra;
range rb=[Book1]Sheet1!col(D);
layer.x.label.dataset$=rb;
layer.x.label.type = 8;
