tiledlayout no spacing display in 2x3 grid

How to plot tiledlayout 2x3 grid without any spacing between plots? I'm using these commands

t = tiledlayout(2,3);

t.TileSpacing = 'none';

but still have spacing between the columns.

It seems to do the right thing in this case:

t = tiledlayout(2,3);
t.TileSpacing = 'none';

for ii = 1:6
    nexttile(t)
    plot(1:10)
end

Maybe something in your plotting code is changing the spacing. Can you share the rest of your code?

fh=figure;

fh.WindowState = 'maximized';

t = tiledlayout(2,3);

t.TileSpacing = 'none';

nexttile

% read img

imshow(img)

for idx = 1:5

nexttile

% read img

imshow(img)

end

This is essentially what I'm running, I'm wondering if I have to adjust the aspect ratio.

imshow fits the axes to your image size.

Use axis normal if you don't want the axes to tighten. This will distort your image if you expect it to have a uniform aspect ratio.

Example showing default behavior (axis on to see borders)

figure
tiledlayout(2,2,'TileSpacing','None');
for i = 1:4
    nexttile
    imshow(rand(700,300))
    axis on
end

Example after applying axis normal (axis on to see borders)

figure
tiledlayout(2,2,'TileSpacing','None');
for i = 1:4
    nexttile
    imshow(rand(700,300))
    axis normal
    axis on
end

Answer 2

imshow effectively sets the aspect ratio so that the image doesn't look distorted.

If you want to have no space between the tiles, at the expense of potentially distorting the images, one way to do that would be to use the low-level image function instead of imshow:

% some random image data
image_data = cell(2,3);
for ii = 1:6
    image_data{ii} = randi([0 255],20,8,3,'uint8');
end

% first, using imshow, for reference
figure
t = tiledlayout(2,3);
t.TileSpacing = 'none';
for ii = 1:6
    nexttile(t)
    imshow(image_data{ii})
end

% now, using image. images are stretched, but there's no space between them
figure
t = tiledlayout(2,3);
t.TileSpacing = 'none';
for ii = 1:6
    nexttile(t)
    image(image_data{ii})
end

Both suggestions above makes sense, but I would like to keep the aspect ratio of the image, so I guess I would have to accept some column spacing.

Thanks for the help though.

Not sure what the end goal is but maybe imtile would come in handy.
