switch (s)
case 7

F= input('Enter frequency:');
t=0:0.01:4;
y= A*sin(2*pi*F*t);
plot(t,y,'b')
title ('Sine Wave')
xlabel ('Time')
ylabel('Amplitude')
grid on
hold on
switch (a)
case 1 %time scale
z= input('Enter time scale value:');
y= A*sin(2*pi*F*t);
plot((z\t),y,'k')
grid on
hold off
case 2 %time shifting
z= input('Enter time shifting value:');
y= A*sin(2*pi*F*t);
plot((t-z),y,'k')
grid on
hold off
case 3 %time inversion
y= A*sin(2*pi*F*(-t));
plot(t,y,'g')
grid on
hold off
case 4 %amplitude scale
z=input('Enter amplitude scale value:');
y= z*(A*sin(2*pi*F*t));
plot(t,y,'k');
grid on
hold off
case 5 %amplitude shift
z=input('Enter amplitude shift value:');
y= (A*sin(2*pi*F*t))-z;
plot(t,y,'k');
grid on
hold off
case 6 %amplitude inversion
y= -A*sin(2*pi*F*t);
plot(t,y,'k')
grid on
hold off
end
i want the graph to be like this automatically

There's no need for all this code repetition. The cases should not be nested. Create the unmodified vectors, create the modified copies, then plot.
fprintf('Please choose any type of signal below.\n1. Impulse\n2. Step function\n3. DC Source\n4. Signum function\n5. Rising exponent function\n6. Cosine function\n7. Sine function\n8. Square function\n9. Triangular function\n10. Symmetrical decaying exponent function')
s = input('\nSignal number: ');
a = input('Please choose any of these signal transformation\n1. Time scale\n2. Time shift\n3. Time inversion\n4. Amplitude scale\n5. Amplitude Shift\n6. Amplitude inversion\n');
switch (s)
% ... other cases
case 7
A = input('Enter Amplitude: '); % trailing space for clarity
F = input('Enter frequency: ');
t = 0:0.01:4;
y = A*sin(2*pi*F*t);
figtitle = 'Sine Wave'; % for later
% ... other cases
end
switch (a)
% ... other cases
case 2 %time shifting
z = input('Enter time shifting value: ');
tmod = t-z;
ymod = y;
% ... other cases
case 4 %amplitude scale
z = input('Enter amplitude scale value: ');
tmod = t;
ymod = z*y;
% ... other cases
end
% do the plotting last
plot(t,y,'b')
hold on
plot(tmod,ymod,'k')
hold off
title(figtitle)
xlabel('Time')
ylabel('Amplitude')
grid on
xlim(xlim + [-1 1]*range(xlim)*0.2)
ylim(ylim + [-1 1]*range(ylim)*0.2)
