g = 9.8;
x0 = 0;
t = 0:.01:15;
Vo = 'What is the Initial Velocity? ';
Vo = input(Vo);
Theta = 'What is the Angle? ';
Theta = input(Theta);
y0 = 'What is the Initial Y position? ';
y0 = input(y0);
x = x0+Vo*cosd(Theta)*t;
y = y0+Vo*sind(Theta)*t-(g*t.^2)/2;
plot (x,y, 'Linewidth', 3)
I am seeking help once again since I am still confused. My graph is flat, no matter what angle I enter. My graph also starts at a negative number, and I want it to start at 0, but dont know how. Does anyone know how to fix this?

Your code works when I run it with:
Vo = 100;
Theta = 45;
y0 = 0;

For what it's worth, I'm attaching my projectile demo where it computes and plots practically everything you could ever want to know about a projectile.
