Why is there nothing on my graph?

% Constants A, B, and C for Water
A=11.6834
B=3816.44
C=46.13
for T=0:10:100 ;
    P=10.^(A-(B./(C+T)))
end 
plot(T,P);
axis([0 10  0 1])
xlabel ('Temperature [k]')
ylabel ('Pressure [bar]')
title ('Saturation Pressures for Water and Methanol')

Each iteration of the for loop, you overwrite all of P.

I suggest you do not use a for loop. Instead:

T = 0:10:100;
P = 10.^(A-(B./(C+T)));
