Select the "Data Cursor" on the figure window and click on the point you want.
Hold "alt" to multiple selection.

you have to know the xy coordinates of those points to mark them . suppose i have a graph Y(X) :
X=1:10;Y=randn(1,10);
plot(X,Y), hold on,
Marked=[X(2) Y(2); X(4) Y(4)];
plot(Marked(:,1),Marked(:,2),'o');
