How to set axis of scatter3?

Hi, I have a for loop that basically continuously plots points using drawnow corresponding to particles in an explosion. So far, I've got the 3D scatter plot to continuously graph the explosion, its just that the axis continually readjusts every couple iterations, and the point motion is distorted because of it. Is there any way to set the axis of scatter3D? I've checked online everywhere and couldn't find an answer. Axis() doesn't seem to do anything. Thanks

Here is an example with unfixed axes, and fixed axes:

% Unfixed axes
figure
for N = 1:10
    pause(0.5)
    [X,Y,Z] = sphere(16);
    r = rand(1);
    X = 5*r*X;
    Y = 5*r*Y;
    Z = 5*r*Z;
    x = [0.5*X(:); 0.75*X(:); X(:)];
    y = [0.5*Y(:); 0.75*Y(:); Y(:)];
    z = [0.5*Z(:); 0.75*Z(:); Z(:)];
    scatter3(x,y,z)
end

% Fixed axes
figure
for N = 1:10
    pause(0.5)
    [X,Y,Z] = sphere(16);
    r = rand(1);
    X = 5*r*X;
    Y = 5*r*Y;
    Z = 5*r*Z;
    x = [0.5*X(:); 0.75*X(:); X(:)];
    y = [0.5*Y(:); 0.75*Y(:); Y(:)];
    z = [0.5*Z(:); 0.75*Z(:); Z(:)];
    scatter3(x,y,z)
    set(gca,'XLim',[-3 3],'YLim',[-3 3],'ZLim',[-3 3])
end

Actually this worked well! Thanks

Hello there,

I´ve computed a 3D plots to demonstrate the idea of linesearch and I want to have the view (-86,35) but if I do so, the outer black frame is distorted as well as the points I´ve computed with

plot3(xk(1),xk(2),fk+foff,'o','LineWidth',4,'Color',acinred)

I´ve thought that these commands will help:

set(gca,'XTick',[],'YTick',[],'ZTick',[])
box on

but the problem still occurs... does anyone know what might be the problem? I´ve tried axis equal, but that doesn´t help at all.

Thanks in advance,

Sophie

 axis([your values])
 hold on

This seemed to work for the axis, but it slowed the plotting significantly. I'm trying to plot 1000 particles over thousands of timesteps. I also tried the below method but similar results
