I have written the following code in which couple of checkboxes will be generated on a plot.

Now, I want to make it in a way that for every checkbox, a specific plot is being shown if the checkbox is checked by the user.

The problem is I can not use the variables such as my loop index inside the Callback function.

I would appreciate if someone could help me.

for i=1:AnSwer
        cellwithstruct=d.channels(i);
        chkbox=uicontrol('Style','checkbox','String',cellwithstruct{1}.name,'position',[10 25*(i-1) 60 20], ...
            'Callback',@myCallbackfunc);
        plot(time_vector,d.samples(i,:));grid minor;%This is the plot that I want to use inside the Callback function
end

The format for callback function is:

function myCallbackfunc(hObject, ~, ~)
if (get(hObject,'Value') == get(hObject,'Max'))
	%The plot should be done here;
else
	%The plot should be erased here;
end
end
