The easiest thing would be to use the hold command to prevent the plot being overwritten every time you call plot. The general code structure would be:
figure
hold on
while CONDITION
plot(STUFF)
end
For more information, check the documentation at https://www.mathworks.com/help/matlab/ref/hold.html.
The other thing to note is that the default plot style is a line with no markers... so if you want to plot individual points one at a time, then for example you can do them as red circular markers:
plot(STUFF,'ro');
