How to set graphics in diferents axes in a same GUI

Hi guys, I need your help, I'm working in a line codificator and my problem is when I push the buttom "ejecutar" the graphic appear in the the same axes, I've codificated all the buttoms "ejecutar" for separate, the idea is when i push the buttom ejecutar the graphic have to appear in the correct axes.

I don't know where I have to change the code for fix that, thanks for your help guys.

Mi code is the next:

a=str2double(get(handles.edit1,'String'));
b=str2double(get(handles.edit2,'String'));
c=str2double(get(handles.edit3,'String'));
d=str2double(get(handles.edit4,'String'));
e=str2double(get(handles.edit5,'String'));
f=str2double(get(handles.edit6,'String'));
g=str2double(get(handles.edit7,'String'));
h=str2double(get(handles.edit8,'String'));
i0=str2double(get(handles.edit9,'String'));
j0=str2double(get(handles.edit10,'String'));

handles.bits=[a,b,c,d,e,f,g,h,i0,j0];
handles.cod=get(hObject,'Value');
hold off;
        h =handles.bits;
        n=1;
        h(11)=1;
        ami=-1;
        while n<=10;
            t=n-1:0.001:n;
        if h(n) == 0
            if h(n+1)==0  
                y=(t>n);
            else
                if ami==1
                    y=-(t==n);
                else
                    y=(t==n);
                end
            end
            d=plot(t,y);title('AMI NRZ');grid on
            set(d,'LineWidth',2.5);
            hold on;
            axis([0 10 -1.5 1.5]);
        else
            ami=ami*-1;
            if h(n+1)==0
                if ami==1
                    y=(t<n);
                else
                    y=-(t<n);
                end
            else
                if ami==1
                    y=(t<n)-(t==n);
                else
                    y=-(t<n)+(t==n);
                end
            end
            d=plot(t,y);title('AMI NRZ');grid on;
            set(d,'LineWidth',2.5);
            hold on;
            axis([0 10 -1.5 1.5]);
        end
        n=n+1;
        end
