Hi very simple, but I can not :(

See here%%%%

"

 function Axes
N.fh=figure('unit','pix',...
    'Position',[400 300 300 300],...
    'MenuBar','None',...
    'Resize','off',...
    'Name','Axes Find problem',...
    'Numbertit','off');

 N.img1 = axes('Parent',N.fh,...
    'Unit','pix',...
    'Position',[20 100 100 100]);

 N.img2 = axes('Parent',N.fh,...
    'Unit','pix',...
    'Position',[180 100 100 100]);

 N.Push(1) = uicontrol('style','push',...
'position',[45 220 50 30],...
'Stri','image 1',...
'backgr',[0.90 0.90 0.90],...
'Callback',{@Push_1,N});

 N.Push(2) = uicontrol('style','push',...
'position',[205 220 50 30],...
'Stri','image 2',...
'backgr',[0.90 0.90 0.90],...
'Callback',{@Push_2,N});

 set([N.img1,N.img2],'CreateFcn',{@Image_CreateFcn,N})

 function Image_CreateFcn

 function Push_1(varargin)
N.Damage1=imread('cat.jpg');
axes(N.img1)    %%%%ERROR
imshow(N.Damage1); 

 function Push_2(varargin)
N.Damage1=imread('dog.jpg');
axes(N.img2)    %%%%ERROR
imshow(N.Damage1);

I get an error, what's wrong?

@nsbd: Please post the text directly.

You do not get an error but a warning. Calling AXES at first takes 0.1 seconds longer. More efficient is "imshow(H.Image2, 'Parent', H.axe(2));".

[nsbd]

Thks. was finally :)

You have a scope issue. Try doing this instead (note the "end"s)

 function Axes
N.fh=figure('unit','pix',...
    'Position',[400 300 300 300],...
    'MenuBar','None',...
    'Resize','off',...
    'Name','Axes Find problem',...
    'Numbertit','off');
 N.img1 = axes('Parent',N.fh,...
    'Unit','pix',...
    'Position',[20 100 100 100]);
 N.img2 = axes('Parent',N.fh,...
    'Unit','pix',...
    'Position',[180 100 100 100]);
 N.Push(1) = uicontrol('style','push',...
'position',[45 220 50 30],...
'Stri','image 1',...
'backgr',[0.90 0.90 0.90],...
'Callback',{@Push_1,N});
 N.Push(2) = uicontrol('style','push',...
'position',[205 220 50 30],...
'Stri','image 2',...
'backgr',[0.90 0.90 0.90],...
'Callback',{@Push_2,N});
 set([N.img1,N.img2],'CreateFcn',{@Image_CreateFcn,N})
 function Image_CreateFcn
 end
 function Push_1(varargin)
   N.Damage1=imread('cat.jpg');
   axes(N.img1)    %%%%ERROR
   imshow(N.Damage1); 
 end
 function Push_2(varargin)
   N.Damage1=imread('dog.jpg');
   axes(N.img2)    %%%%ERROR
   imshow(N.Damage1);
 end
end

Your N structure was not able to be reached in all of the functions without passing it into the different functions. By containing everything within 1 main function, your N structure is accessible by all subfunctions (your callbacks).

I didn't want to.

I wrote my way,After deleting the line,not only takes pictures N.img2,

thanks anyway

[nsbd]

N.img1 for N.Push_1 I want to show

N.img2 for N.Push_2 I want to show

@nsbd: Do not use "Axes" as name of a function. It is confusing, because "axes" is a built-in function already.

Please explain, why you do not "want" to use the Nathan's working solution.

You've sent me an email with a link to this thread. I really do not like to get such emails.

If I find the time to read a question and I have an answer, I will post it. If I do not post an answer, I either do not have the time to read it, or I do not have an answer. In both cases reading and deleting your email is a waste of time for me.

Instead of annoying the contributors, it would be a much better strategy to include a question in your post. See: How to ask a question and How do I write a good question.

Please care about Nathan's answer.

@Walter and Matt: If you think, that this answer is too off-topic, I do not hesitate to delete it. I simply do not want to be spammed anymore.

[nsbd]

Sorry.don't send a message now. Thank you anyway

[Jan]

@nsbd: Ok.
