[Eeglablist] Adding ticks to the main plot

[James Desjardins]

Hi Mary-Jane,

To edit the axes of all the channel ERPs in the main figure produced  
by pop_chanplot() you need to access the handles of the children axes.

First create a vector containing the handles to the children axes in  
the current main ERP figure as follows:

h_child=get(gcf,'Children');


You can then get a list of the axis properties for the first child as follows:

get(h_child(1))


To change properties in children axes you can run a loop from the  
command line that goes through each handle and sets properties (note  
that the final child is the main background so you probably won't need  
to make any changes to that one). For example copying the following to  
the command line will go through all of the child handles (except the  
last one) and change the property "Visible" to "on", "Box" to "off"  
and "Color" to "none".

for i=1:length(h_child)-1;
	set(h_child(i),'Visible','on', ...
	'Box', 'off', ...
	'Color','none');
end
