That should be axes('Parent',h1);

That does not clear the existing axes or image. Instead, it is
putting the new axis right on top of the old one, as you did not
specify a position or size for the new axis. If you look closely,
you will probably notice that the x and y axis labels are doubled,
two sets of labels in the same area.

Hi, George

I thought axes() won't change previous axes objects, but
when I tried the following codes, the image displayed were
cleared by an new axes.

Here's my code,

figure;
h1 = gcf;
axes(h1)
imshow(imread('lego08.gif')) %display an image
figure(h1);axes %create another axes.

By the way, if there's no way to add axes without affecting
previous axes objects. Is it possible to display multiple
images on the same axes without overlapping?

Thanks!

JK Wang

Just do it. The axes() function does not clear the figure.

Adding New Axes Object to a Figure

jk Wang — Mon, 28 Jan 2008 03:07:01 -0500

Hi,guys,

I want to write a program that can adding new axes, but
without changing the other axes existing on the figure. All
of these axes display different images.

So how can I keep the former axes (and their images)
unchanged while adding a new one? Help me please~

Thank you!!!
