Im trying to plot these lines and it is just showing the point but not the lines for the plot any thoughts here is the code.

%output the Revenue and Total Cost plot

figure('color','w');

plot(y,Tcost,'r--','linewidth',3) ;

hold on

plot(y,revenue_cost_wpy,'linewidth',3) ;

hold on

plot(breakeven,'o k','Markerfacecolor','k');

grid on

title('Revenue and Total Cost')

xlabel('Number of Years (Y)')

ylabel('Revenue and Cost [$]')

%plot profit plot

figure('color','w')

plot(y, profit,'g-.','linewidth',2.5);

Hi, it is difficult to provide an exact solution without your original data. However, when I executed your code with demo data, it is giving output as expected.

close all;clc;clear;

% Example data for test
y = 1:100;
Tcost = linspace(10,80,100);
revenue_cost_wpy = linspace(0,100,100); 
profit = revenue_cost_wpy - Tcost; 
breakeven = 32;

% Plotting
figure('color','w');
plot(y,Tcost,'r--','linewidth',3) ;
hold all;
plot(y,revenue_cost_wpy,'linewidth',3) ;
plot(y,breakeven,'o k','Markerfacecolor','k');
grid on;
title('Revenue and Total Cost');
xlabel('Number of Years (Y)');
ylabel('Revenue and Cost [$]');
legend({'Total Cost','Revenue','Breakeven'},'location','northwest');
figure('color','w');
plot(y, profit,'g-.','linewidth',2.5);
hold on;
plot(breakeven,profit,'o k','Markerfacecolor','k');
grid on;
title('Profit');
xlabel('Number of Years (Y)');
ylabel('Profit of the construction choice [$]');
legend('Profit','location','northwest');
hold off;

Check whether these kind of output is expected or not.

Hope this helps!
