Changing the same property of some axis children using subsasgn

3 views (last 30 days)
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.NextPlot = 'add';
plot(ax1,[1,2],[3,4],'DisplayName','graph 1')
plot(ax1,[1,2],1.5*[3,4],'DisplayName','graph 2')
toHide = findobj(ax1,'-regexp','DisplayName','graph');
%% Method 1
toHide(:).Visible = {'off','off'};
%% Method 2
S = substruct('()',{':'},'.','Visible');
toHide(:).Visible = subsasgn( toHide , S , {'off','off'} );

I assume you know that subsasgn is called implicitly whenever you make an assignment statement, as in the following:

No, it cannot be done solely with subsasgn, with no loops.
