Question related to pcolor bar and its position

Hi! Can anyone please tell me

a) how can I use one long pcolorbar at the right side of this figure instead of using 4 different colorbar for four subplots?

This is the figure -

b) How to minimize the distances between teh four subplots, so that they are put closer to each other?

The code I am using for the plot is this -

for ii = 1:4
    ax(ii) = subplot(2,2,ii);
    h{ii} = pcolor(LON,LAT,flip(Tide_type{ii}));
    set(h{ii}, 'EdgeColor', 'none');
    shading interp;
    colorbar;
    caxis([12.5 15.5]);
    setup_plots(ax(ii))
end

Any feedback will be much appreaciated, thank you!!

tiledlayout can supposedly get tiles closer together than subplot does.

You can manually change the position of the colorbar using the 'position' property. Here's an example:

fig = figure;
subplot(2,2,1)
imagesc([0 1 0; 1 2 1; 0 1 0;])
subplot(2,2,2)
imagesc([0 1 0; 1 2 1; 0 1 0;])
subplot(2,2,3)
imagesc([0 1 0; 1 2 1; 0 1 0;])
subplot(2,2,4)
imagesc([0 1 0; 1 2 1; 0 1 0;])

pos = get(subplot(2,2,4),'Position');
colorbar('Position', [pos(1)+pos(3)+0.01  pos(2)  0.03  pos(2)+pos(4)*2.07])

Note that this is a little bit easier using tiledlayout instead of subplot, plus it is easier to control the spacing between and around the tiles. Details on the spacing options are here

figure
tl = tiledlayout(2,2, 'TileSpacing', 'compact', 'Padding', 'compact');
nexttile
imagesc([0 1 0; 1 2 1; 0 1 0;])
nexttile
imagesc([0 1 0; 1 2 1; 0 1 0;])
nexttile
imagesc([0 1 0; 1 2 1; 0 1 0;])
nexttile
imagesc([0 1 0; 1 2 1; 0 1 0;])

cbh = colorbar;
cbh.Layout.Tile = 'east';
