[Guide, R2012b] Add or remove legend if plot visibility is switched On/Off

Hey everyone,

I am having problems to find the right command lines to update the axes with the selected shown plots. My Gui allows to show which plots are shown by using a system of checkboxes

The checkboxes are in a uitable and the callback function fro the CellEditCallback is the following:

function fctTable(hObject, eventdata)
handles = guidata(hObject);
if eventdata.Indices(2) == 1
    if eventdata.NewData == 0
        set(handles.plots{eventdata.Indices(1)}, 'visible', 'off');
    else
        set(handles.plots{eventdata.Indices(1)}, 'visible', 'on')
    end
end
guidata(hObject, handles);
end

% --- Executes on button press in PB_load.
function PB_load_Callback(hObject, eventdata, handles)
handles = guidata(hObject);

[FileName,PathName] = uigetfile('*.txt');
if FileName == 0
    return
else
    cla(handles.axes1);
    [~, name] = fileparts(FileName);
    fileName = fopen(fullfile(PathName, FileName),'r');
    C = textscan(fileName,...
    '%s %s %s %s %s %s %s %s %s %s %s %s %s %s %s %s %s %s',...
    'Delimiter', ';');
end
for i = 1:length(C)
    handles.colors{i}= rand(1,3);
end
.
.
.
a = 1;
for i = 1:2:15
    handles.plots{a} = plot(A, channel(a).current, 'color',...
            handles.colors{i},'DisplayName', strcat('channel\_', num2str(a-1)));
    a = a+1;
end
legend('show');
guidata(hObject, handles)
end
I will attach the files if someone want to try the code.
Thanks in advance.

This is how I have solved it:

I have created a pushbutton to update the legend, having the following callback fct:

function PB_UpdateLegend_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
table = get(handles.uitable1, 'Data');
idx = find([table{:,1}] == 1);
legend([handles.plots{idx}], {handles.legend{idx}});
guidata(hObject, handles);
end

As always I attach the files to test the code if you want to sue the same system
