Graphing does not appear

Please Help my graph wont appear and my Y-axis intervals are off

clc;
clear all;
close all;

B=2500; %starting Balance of the account
C=50; %amount added per month
I=B*0.004; %claculating the interest of accoungt  
t=0:1:216;%time intervals for graph counting by month

for i=0:1:216 %There are 216 months in 18 years, incrementing by 1 so per month
 Bf=B+I+C; %calculating the New Balance of the Account
 fprintf('%6.2f \n',Bf)
end
plot(t,Bf) %graphing values
xlabel('Time in Months')
ylabel('Balance of the Acount ($)')

The plot will appear if you subscript ‘Bf’:

for i=1:numel(t) %There are 216 months in 18 years, incrementing by 1 so per month
    Bf(i)=B+I+C; %calculating the New Balance of the Account
    fprintf('%6.2f \n',Bf(i))
end

However your code has other problems (the amount does not accrue), and since this appears to be homework, I will leave you to it.
