How to place a common colorbar for tiledlayout plots?

51 views (last 30 days)
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?

tiledlayout(2,2)
nexttile; nexttile; nexttile; nexttile
cb = colorbar;
cb.Layout.Tile = 'east';

You must apply cmocean in all the nexttile blocks. Currently you are only doing so in the last block.
