How to plot the results?

for T=120:10:230
Ao=4.2968;A1=-3.4709*10^-1;A2=-1.1008*(10^-1);A3=1.4812*(10^-2);
A4=-1/1150*(10^-3);b1=1.29*(10^-5); b2=4.86*(10^3);
l=100;
l1=l/1000; %conversion in meters
D=25;
R=D/2000; %conversion in meters and radius
m=10;
T1=T+273.15; %conversion to Kelvins
roh=0.7;
Q=m/roh;
Q1=Q/(100^3);
St=((4*Q1)/(pi*R.^3));
aT=b1*exp(b2./T1);
lA1=log10(aT.*St);
n=1+A1+2*A2*lA1+3*A3*(lA1.^2)+4*A4*(lA1.^3);
n1=1./n;
eta=log10(aT)+Ao+A1.*lA1+A2*(lA1.^2)+A3.*(lA1.^3)+A4.*(lA1.^4);
eta1=10.^eta;
ShSt=eta1.*St;
K=St./(ShSt.^n1);
B1=(3+n1)./n1;
B2=(pi/4).^1./n1;
G=B2.*((R').^B1)./(2.*l1);
P1=(Q1.^(1./n1));
P2=(K.^(1./n1));
P=P1./(P2.*G);
end
