Using the listdlg function

I am using the listdlg function and using 'Multiple' so the user can select mulitple items. When using the 'if,elseif' or the 'case' statements, they wont work when selecting mutiple items. They will work however if i only select one item from the list. The case statement spits out the code 'SWITCH expression must be a scalar or a character vector' and the 'if' statement spits a vector when i am trying to plot multiple bar graphs.
Any help would be great thanks.

Same problem for me, the output is a vector but I dont know what to do with it. (Im still a newbie)
Like @Les Beckham shows, loop over the values returned by listdlg()

You probably just need to wrap your switch/case processing in a for loop. For example:
s = listdlg('ListString', {'One', 'Two', 'Three'});
for ii = 1:numel(s)
switch s(ii)
case 1
% do something
case 2
% do something different
case 3
% do something else
end
end
