Hello, quick question about a problem I have. Is it possible to delete or hide some points of a surface. I don't want to redraw the surface everytime but just make some points appear or disappear. Any idea ? Many thanks, Kevin

Hi Kevin,
something like this?
data = peaks(25);
h = surf(data);
% delete one point (in fact delete all 4 patches containing this point
data(3,3) = NaN;
set(h, 'zdata', data)

figure;hold on; h1=plot(1,1,'b.'); h2=plot(2,2,'r.'); hold off
% if you want to hide h2
% if you want to delete h2

I have the same question but for the function 'probplot'.
It is more complex cause if you omitsome points , the probability plot changes...
I need a real hiding process that acts only on the plotted points and not on the raw data. This is pretty simple in JMP.Could you please advise ?
