Delete/Hide points of a surface

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);
pause(3);
% delete one point (in fact delete all 4 patches containing this point
data(3,3) = NaN;
set(h, 'zdata', data)

yes exactly ! this should hide data(3,3) after the pause. In my case I stored the original data in an external one so I can replot the points (my idea is to make some part of a surface on and off during a specific time)

Thank you Titus

figure;hold on; h1=plot(1,1,'b.'); h2=plot(2,2,'r.'); hold off

% if you want to hide h2

set(h2,'visible','off')

% if you want to delete h2

delete(h2)

That's not exactly what I need because I can't plot my surface in two part.

Actually I found out that turning some values to NaN hide the points on the surface.

Hello,

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 ?
