How do you "make some dots in an axes"? Isn't it possible to count the dots during creation already?

Is this what you want
E.G.
close all
clear variables %changed from clear all on Jan's suggestion
disp('Hit return (enter) to stop entering points');
[x,y]=ginput; % hit return(enter) to stop entering points
plot(x,y,'MarkerFaceColor',[0 0 0],'MarkerEdgeColor',[0 0 0],'Marker','o','LineStyle','none');
num_points=(length(x))

@Thomas, I would not have mentioned the problems of "clear all", if this appears less frequently in this forum. It does not cause any problems in your example. But I see it in so many examples, even as first line inside functions -where it is even weird-, that I suggest repeatedly to avoid it. A lot of FEX submissions contain "clear all, close all" and testing them can destroy my current work.
