What kind of graphic object are those for? Were you using rectangle() ? Or bar() ?

histograms (I'm ploting multiple signals from a detector)

Try this example

surf(peaks,'facecolor','none')          % plot peaks
surface(membrane,'facecolor','none')    % plot membrane
h = legend('surf','memb');              % show legend
h1 = get(h,'children');                 % get handle of each object in legend
for i = 1:length(h1)                    % loop through each object
    if strcmp(get(h1(i),'type'),'patch')% if an object is a patch
        cc = get(h1(i),'edgecolor');    % get edgecolor
        set(h1(i),'facecolor',cc)       % set facecolor
    end
end
