Basically I want to make my comet line in my plot to be black, with a thick line or perferebly ball.

This is what i have:

dt = 2.5;

ddt = 0:dt:10;

%Plot animation

for index = 1:length(ddt)

comet(H,t)

xlim([-2,2])

ylim([min(H),max(H)])

pause(dt)

end

This puts out a orange coment thats a line, any way I can make it black and and ball?

If not a ball then what i really want it to be black.

You can make your required plot using a loop.

x = linspace(0,2*pi,1000) ;
y = sin(x) ; 
for i = 1:length(x)
    plot(x(1:i),y(1:i),'r')
    drawnow
end
