Two patches in one figure

Hi,

please I'm trying to make two patches in one figure, after plotting the first one it disappears and I get the second one 'disk2' only. I've tried 'hold on' but it doesn't work

basically I've this piece of code for plotting

for ii=1:length(y)

set(disk1, 'xdata', xcirc1(:,ii), 'ydata', ycirc1(:,ii), 'zdata', zcirc1(:,ii));

set(disk2, 'xdata', xcirc2(:,ii), 'ydata', ycirc2(:,ii), 'zdata', zcirc2(:,ii));

   drawnow

    pause(0.01)

end

Any one could please give me suggestion for solving it.

Thank you.

Can you provide a minimal working example that reproduces the problem?

Hi Chad, Unfortunately the code is pretty long to be posted here, basically after sitting the patch for the disks as following :

disk1= patch('xdata', xcirc1(:,1), 'ydata', ycirc1(:,1), 'zdata', zcirc1(:,1));

disk2= patch('xdata', xcirc2(:,1), 'ydata', ycirc2(:,1), 'zdata', zcirc2(:,1)); I use the code "in the main post" for plotting.

How do you calculate the ‘xcirc’, ‘ycirc’, and ‘zirc’ vectors? What are you plotting?

What do you want your plot to show?

Hi star, I'm trying to plot a disk in three dimension. and xcirc, ycirc zcirc; are the matrices for plotting it.

It should work. Please try it again:

axes('nextplot, 'add');  % Like "hold on"
disk1 = patch('xdata', xcirc1(:,1), 'ydata', ycirc1(:,1), 'zdata', zcirc1(:,1));
disk2 = patch('xdata', xcirc2(:,1), 'ydata', ycirc2(:,1), 'zdata', zcirc2(:,1));
for ii = 1:length(y)
  set(disk1, 'xdata', xcirc1(:,ii), 'ydata', ycirc1(:,ii), 'zdata', zcirc1(:,ii));
  set(disk2, 'xdata', xcirc2(:,ii), 'ydata', ycirc2(:,ii), 'zdata', zcirc2(:,ii));
  drawnow
  pause(0.01)
end

If the coordinates are not Inf or NaN and are within the axes limits and the view direction is not parallel to the planes of the circles, the patches must be visible.

Many thanks Jan, in your footnote you mentioned many vital aspects. for me I forgot to check my axes limits.
