Is it possible to delete "subplots"?

For example I have a figure and five plots on it. I would like to start a new figure with the same plots, except the last one. Is it possible to recall the previous ones?

Yes it is:
figure
hold on
h1=subplot(1,2,1)
plot(1:10,'r');
h2=subplot(1,2,2)
plot(2:11,'g');
pause(2)
delete(h2)
however, you'll still see the empty space where the subplot was before.

Did you figure out how to make your markers transparant by the way? You asked the question yesterday, I answered but you didn't respond!

If you haven't already saved the handles when creating the axes, you can first get the handles with
haxes=get(gcf,'children');
and then recreate them with
haxes_new=copyobj(haxes(2:end),figure);
Of course, the position of the axes remains this way. Alternatively, you could only copy the plots with (haxes as before):
figure
for cnt=1:4
hplots=get(haxes(end-cnt+1),'children');
copyobj(hplots, subplot(2,2,cnt));
end
And the axes will be aligned as usual.

Mr. M has written: "No, I am not using subplots (sorry for the ""), just plots on each other! So I would like to keep for example some shapes or functions on the plot. Or I would like to keep some settings, for example axis, titles, legends, etc. But not all."
-----------------
My response:
Ok, no subplots here. I would copy the axes with copyobj:
ha_new=copyobj(gca,figure);
Then get the handles of the children with
hc=get(ha_new,'children');
and finally delete some of the children (less cruel than it sounds):
delete(hc(1:4))
deletes the 4 children which have been added latest. You could also specify certain properties of lines to delete:
delete(hc(cellfun(@(c) isequal(c,[0 0 1]),get(hc,'color'))))
deletes all blue lines.

X=1:10;
Y=X.^2;
Z=X.^3;
figure
hold on
p1=plot(X,Y);
p2=plot(X,Z);
pause(2)
delete(p2)
