You're creating one line per ginput call, plotting one point per line. They're not all the same line object so they're not connected. I would create an animatedline object before entering the while loop and addpoints to it inside.
h = animatedline('Marker', '*', 'LineStyle', '-');
while 1
[x,y,button]=ginput(1);
switch button
case 1
addpoints(h, x, y);
case{'q','Q'}
break;
end
end

Specify additional properties of the animatedline when you construct it, like I did with the Marker and LineStyle properties. The properties you can change are listed on this documentation page.
