How to plot the graph of Greatest Integer Function ?

I was trying to plot greatest integer function by using floor command and stem (to show discontinuity) but what i am getting is,please help me out!!!

I used the code

x=linspace(1,10,10) y=floor(x); stem(x,y)

What did you expect to see?

This is close, I got this using the code below:

Dots are right, lines are going wrong way.

Code:

syms y

>> y=floor(x); x=linspace(1,10,10); stem(x,y)

x=linspace(1,10,10)
y=floor(x) % ARE THESE VALUES AS EXPECTED??

stairs(x,y) % rather than stem

Sorry brother,but this is showing a continuous graph whereas the greatest integer function is a discontinuous function,sorry but this plot is wrong

x=1:0.001:10;
y=floor(x); 
plot(x,y,'.');
