Hi,

I had issues in drawing worldmap after imshow or surf commands, hope somebody could help me. I put the corresponding problematic figures at

http://jaxforum.webs.com/apps/photos/album?albumid=9550438

for your information.

Here are the codes with my comments parenthesized:

sz = get(0, 'ScreenSize');
im1 = rand(300);
latlim = [20 83]; lonlim = [-180 -80];
handle = figure('position', [150 150 sz(3)*3/5 sz(3)*3/10]);
ah1 = axes('parent', handle, 'position', [0.04 0.06 .45 .88]);
ah2 = axes('parent', handle, 'position', [0.53 0.06 .45 .88]);
axes(ah1)
imshow(im1)
worldmap(latlim, lonlim)

{Two problems occur. First, there is a rectangular box overlapping the right side of the figure. Second, the worldmap is drawn upside down. if I type}

worldmap(latlim, lonlim)

{this removes the box but the map is still upside down. Draw worldmap in the second axes}

axes(ah2)
worldmap(latlim, lonlim)

{Now the worldmap is correct}

drawing worldmap after surf command is even worse. If I draw surf after worldmap I should use hold off to remove the effect of the world map. However there is always the problem with the worldmap command after surf.
I did:

delete(handle); delete(ah1); delete(ah2);
handle = figure('position', [150 150 sz(3)*3/5 sz(3)*3/10]);
ah1 = axes('parent', handle, 'position', [0.04 0.06 .45 .88]);
ah2 = axes('parent', handle, 'position', [0.53 0.06 .45 .88]);
axes(ah1)
surf(peaks)
worldmap(latlim, lonlim)
axes(ah2)
surf(peaks)
hold off
worldmap(latlim, lonlim)

both axes produce the same funny pictures.

Thanks,

Jax Cao
