I wanted to place a large common colorbar towards "east" for a series of plots using tiledlayout. I used the following code:

figure;
t = tiledlayout(2,2,'TileSpacing','none','Padding','none');
nexttile;
imagescn(x,y,A);
cb = colorbar;
hold on;
stipple(x',y',A1);
mymap.EdgeAlpha=0;             %Removes the grids
colorbar;
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
% To set label to colorbar
 h = colorbar;
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('A','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
cb = colorbar;
cmocean('balance','pivot') % sets the colormap with zero in the middle
set(gca,'xticklabel',{[]});set(gca,'yticklabel',{[]});
hold on;
geoshow(shapefile, 'FaceColor', 'none','LineWidth',1);  %No facecolor
set(cb,'FontSize',10)
nexttile;
imagescn(x,y,B);
cb = colorbar;
hold on;
stipple(x',y',B1);
mymap.EdgeAlpha=0;             %Removes the grids
colorbar;
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
% To set label to colorbar
 h = colorbar;
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('B','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
cb = colorbar;
cmocean('balance','pivot') % sets the colormap with zero in the middle
set(gca,'xticklabel',{[]})
set(gca,'yticklabel',{[]})
hold on;
geoshow(shapefile, 'FaceColor', 'none','LineWidth',1);  %No facecolor
set(cb,'FontSize',10)
nexttile;
imagescn(x,y,C);
cb = colorbar;
hold on;
stipple(x',y',C1);
mymap.EdgeAlpha=0;             %Removes the grids
colorbar;
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
% To set label to colorbar
 h = colorbar;
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('C','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
cb = colorbar;
cmocean('balance','pivot') % sets the colormap with zero in the middle
set(gca,'xticklabel',{[]})
set(gca,'yticklabel',{[]})
hold on;
geoshow(shapefile, 'FaceColor', 'none','LineWidth',1);  %No facecolor
set(cb,'FontSize',10)
nexttile;
imagescn(x,y,D);
cb = colorbar;
hold on;
stipple(x',y',D1);
mymap.EdgeAlpha=0;             %Removes the grids
colorbar;
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
% To set label to colorbar
 h = colorbar;
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('D','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
cb = colorbar;
cmocean('balance','pivot') % sets the colormap with zero in the middle
set(gca,'xticklabel',{[]});set(gca,'yticklabel',{[]});

This code is giving individual colorbars for each plot. But I want a common colorbar for all the plots together towards the eastern end. How to do it?

Hi I tried the same, but when I am trying to keep the colorbar patter to "cmocean", only the last plot is following that colormap pattern. How to get the same colorbar format (cmocean) for all the plots? The code I used is this:

figure;
t = tiledlayout(2,2,'TileSpacing','compact','Padding','compact');
nexttile;
imagescn(x,y,A);
hold on;
stipple(x',y',A1);
mymap.EdgeAlpha=0;             %Removes the grids
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
title('A','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
set(gca,'xticklabel',{[]});set(gca,'yticklabel',{[]});
nexttile;
imagescn(x,y,B);
hold on;
stipple(x',y',B1);
mymap.EdgeAlpha=0;             %Removes the grids
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
title('B','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
set(gca,'xticklabel',{[]})
set(gca,'yticklabel',{[]})
nexttile;
imagescn(x,y,C);
hold on;
stipple(x',y',C1);
mymap.EdgeAlpha=0;             %Removes the grids
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('C','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
set(gca,'xticklabel',{[]})
set(gca,'yticklabel',{[]})
nexttile;
imagescn(x,y,D);
hold on;
stipple(x',y',D1);
mymap.EdgeAlpha=0;             %Removes the grids
box on;
set(gca,'linew',2);   % thickens the axis
axis equal;           %important for maps so that there is no stretch
set(gca,'XMinorTick','on','YMinorTick','on');
xlim([min(x) max(x)]); 
ylim([min(y) max(y)]);
%Axis ticks bolded
 set(gca,'TickLabelInterpreter','none');
set(gca,'fontweight','bold','fontsize',12);
title('D','FontWeight','bold','FontSize',14,'FontName','Helvetica'); % title bold and size 14
set(gca,'xticklabel',{[]});set(gca,'yticklabel',{[]});
cb = colorbar;
cb.Layout.Tile = 'east';
>> cmocean('balance','pivot') % sets the colormap with zero in the middle

And I am getting this plot: (I need all the plots following the cmocean colorbar format)

Hi Matt. Sorry for not giving the input variables. I have given it now in the following code:

cmocean('balance','pivot') % sets the colormap with zero in the middle
