Even with all my effort, I can not get my plot to show a line, why?

clc; clear; format compact;

% Intitiating Variables
Obalance = 3000; 
YC = 300; 
time = i;

% Creating For Loop
for i = 1:1:216
    balance = Obalance;
    interest = Obalance*0.005;
    Nbalance(i) = Obalance + interest + YC;
    Obalance = Nbalance(i);
end
fprintf("%.2f", balance);
plot(1:1:216,balance)
xlabel('time');
ylabel('balance');

At the end of your loop, the variable balance is a single number. Maybe you wanted

balance(i) = Obalance

so that balance is a 1x216 array?

[Walter Roberson]

Or plot Nbalance instead of balance . Depending on whether you want to plot the starting balance for the period, or the ending balance for the period.

I troubleshot that myself and you were right, just had to stare at it some more I guess. Thank you for the help.
