Windows 7 Pro SP1 x64

Greetings!

A graph window has page. A page has layers. Layers have plots and graphic objects.
I know a way to loop over graphic objects (https://www.originlab.com/doc/LabTalk/guide/Looping-Over-objs#Looping_Over_Graphic_Objects).
However I couldn't find a way to loop over plots.

https://www.originlab.com/doc/LabTalk/ref/Layer-obj suggests to use
layer.plot

to get or set the active plot number (index).

How do I get the total number of plots in a layer?
How do I loop over the layer plots and modify their formatting?

Thank you.

Basically all looping is in document command.

https://www.originlab.com/doc/labtalk/ref/document-cmd#-e_object_.7Bscript.7D.3B_Execute_the_given_script_for_all_objects

Use set command to modify plot's property.
https://www.originlab.com/doc/Labtalk/Ref/Set-cmd 


// set all scatter plots symbol size as 20
document -e dy {
	set %c -z 20;
};

Got it.

How do I get the total number of plots in a layer into a variable?

Got it.
I could not find this help page easily.

Related question
Can you also comment on the meaning of the dataset while working with graph. I want to understand the difference between plot and dataset (associated with the plot).
For example, while looping through graphs %C contains the name of the active dataset (not active plot). How do I link plot and dataset toghether?

maybe the document is too rough to be precise.

A rough(again...) description is:

loop over graph, it works on plot;
loop over worksheet, it works on dataset (column);
loop over matrix sheet, it works on matrix object.

Thank you.
I agree that the help pages have to be corrected.
Ideally, I want to see an Origin object hierarchy schematics to navigate easily.
