How to get 2 discrete signals into 1 graph?

Basically i need to graph this signal but I graph it part by part:

x[n]={-3n*(n^n-5), 3<=n<6

2, 0<=n<3

0, for every other n

>>n1=[0 1 2];
>> x1=[2 2 2];
>> stem(n1,x1)
>> hold
Current plot held
>> n2=[3 4 5];
>> x2=-3.*n2.*(n2.^n2-5);
>> stem(n2,x2)

But this does not work. Can i even do it part by part or is there more efficient way to draw this signal?

What does ‘not work’ mean?

This works for me:

n1=[0 1 2];
x1=[2 2 2];
stem(n1,x1)
hold on
n2=[3 4 5];
x2=-3.*n2.*(n2.^n2-5);
stem(n2,x2)
hold off
axis([0  6    [-6 1]*1E4])

I did exactly what you wrote but i don't get value 2 on interval 0<=n<3.

It plots correctly. The magnitude of ‘x2’ obscures the details:

figure
n1=[0 1 2];
x1=[2 2 2];
stem(n1,x1)
axis([-1 6  -1 3])

Oh okay, thank you very much.

My pleasure.
