What you are trying is unclear. Is this one? Anyways shiting the x values, you can do it multiple ways, here one way
function shift_plot()
n=input('Enter 1 for left or any other number for right ')
x_data=[1:0.5:10];
y_data=[10:-1:1];
if n==1
stem(x_data(1:10),y_data);
else 
 stem(x_data(end-9:end),y_data);
end
xlim([0 10]);
end
Command Window
Enter 1 for left or any other number for right 5
n =
     5
>> shift_plot()
Enter 1 for left or any other number for right 1
n =
     1
