How to make the following code work in order to change the 'Visible' property of some children plots whose handles are stored in toHide using subsasgn?
f1 = figure;
ax1=axes(f1);
axis(ax1,'tight');
ax1.NextPlot = 'add';
plot(ax1,[1,2],[3,4],'DisplayName','graph 1')
plot(ax1,[1,2],1.5*[3,4],'DisplayName','graph 2')
plot(ax1,[1,2],2*[3,4],'DisplayName','three')
toHide = findobj(ax1,'-regexp','DisplayName','graph');
%% Method 1
toHide(:).Visible = {'off','off'};
%% Method 2
S = substruct('()',{':'},'.','Visible');
toHide(:).Visible = subsasgn( toHide , S , {'off','off'} );

you could use
for nr=1:numel(toHide)
S(1).type='()';
S(1).subs={nr};
S(2).type = '.';
S(2).subs = 'Visible';
toHide = subsasgn( toHide , S , 'off' );
end
if the objects could be indexed directly this would be more easy, but your Method 1 does not work in my matlab

I assume you know that subsasgn is called implicitly whenever you make an assignment statement, as in the following:
[toHide.Visible]=deal('off')
