alpha function affect the things in four axes

hi ,everyone ,when I use the alpha function in a axes(named axes1) in GUI figure , and there are another three axes (named axes2 axes3 axes4)in the GUI figure. then the alpha I used in axes1 affects the things in axes3 and axes4，but not affect the things in axes2，(I select the axes1 before using the alpha function)that's so weird ,my code followed :

axes(handles.axes1);

Ds = smooth3(picgather);

hiso3 = patch(isosurface(Ds,800),'FaceColor',[256/256 192/256 166/256],'EdgeColor','none');

isonormals(Ds,hiso3);

daspect([1,1,0.9]);

alpha(hiso3,0.7);

Please help me ,thanks

the things in axes1 is the object hiso3(just see in the code),the things in other axes are three images, they showed by imshow function ,they are the same size and same type .

Could you post code that can reproduce the issue ?

[jacky chen]

thanks,but it's need a large data(picgather ,showed in code),its size is 256*256*250, the whole code followed : Flag_show = 0;

if isempty(hiso1)

else

   set(hiso1,'visible','off'); 
end
if isempty(hiso2)
else
   set(hiso2,'visible','off');  
end
if isempty(hiso3)
else
   set(hiso3,'visible','off');  
end
if isempty(L1)
else
   set(L1,'visible','off');  
end
if isempty(L2)
else
   set(L2,'visible','off');  
end
axes(handles.axes3);
imshow(tiao_chuang_hou_x(:,:,1),[]);
axes(handles.axes4);
imshow(tiao_chuang_hou_y(:,:,1),[]);
axes(handles.axes1);
%plot skin
Ds = smooth3(picgather);
hiso3 = patch(isosurface(Ds,800),'FaceColor',[256/256 192/256 166/256],'EdgeColor','none'); 
isonormals(Ds,hiso3);
daspect([1,1,0.9]);
alpha(hiso3,0.7);
%plot blood clot
Ds = smooth3(picxuekuai);
hiso1 = patch(isosurface(Ds,0),'FaceColor',[155/256,0,0],'EdgeColor','none'); 
isonormals(Ds,hiso1);
daspect([1,1,0.9]);
L1=light('position',[10000 0 10000]);
L2=light('position',[-10000 0 -10000]);
view(30,30);

anyone interested in this question ,u can new a GUI project ,and then put 4 axes ,then one axes used to plot a three dimension object(maybe some code like this

Ds = smooth3(picgather);

hiso3 = patch(isosurface(Ds,800),'FaceColor',[256/256 192/256 166/256],'EdgeColor','none');

isonormals(Ds,hiso3);

daspect([1,1,0.9]);

alpha(hiso3,0.7);

),the other axes just use the imshow function ,then u maybe get the some problem like me .

finally ,I got it ,it's a horrible question ,the size of three dimension data is 128*128,but the image showed in axes2、3、4 are 512*512，so it changes when the three object created ,then I use the image 256*256，everything goes ok ,it's not the alpha function question ,just the problem of the data ,and the size of image is not larger twice then the three dimension data(one slice ).
