How do I change the type of colorbar for each tiled figure?

Hi,

I have a figure with 4 tiles and manually edited the colorbar and made a new colorbar scheme in the matlab figure, but it only applies to my last tile. How do I get all of them to have the same colorbar scheme?

This is my code:

figure;
tiledlayout(1,4,'TileSpacing','Compact');
%Tile 1 
nexttile
imagesc(TTest_DIF)
xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12); 
ylabel('{\it β}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12)
xticklabels({0 "" 0.2 "" 0.4 "" 0.6 "" 0.8 "" 1})
set(gca, 'xtick', 1:11, 'XTickLabel', xticklabels)
yticklabels({1 "" "" "" "" 0})
set(gca, 'ytick', 1:6, 'YTickLabels', yticklabels)
title('{\Delta_t - \Delta_c}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 14)
clim([-72 11]) % EDIT THESE LIMITS
%Tile 2
nexttile
imagesc(BSITTest_DIF)
%xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 10); 
ylabel('{\it β}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12)
xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12); 
xticklabels({0 "" 0.2 "" 0.4 "" 0.6 "" 0.8 "" 1})
set(gca, 'xtick', 1:11, 'XTickLabel', xticklabels)
yticklabels({1 "" "" "" "" 0})
set(gca, 'ytick', 1:6, 'YTickLabels', yticklabels)
title('{\Delta_B_I_T - \Delta_c}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 14)
clim([-72 11]) % EDIT THESE LIMITS
%tile 3
nexttile
imagesc(Slope_DIF)
%had to change to DeltaSlopeE' in workspace as it was 11x6 not 6x11. 
%xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 10); 
ylabel('{\it β}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12)
xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12); 
xticklabels({0 "" 0.2 "" 0.4 "" 0.6 "" 0.8 "" 1})
set(gca, 'xtick', 1:11, 'XTickLabel', xticklabels)
yticklabels({1 "" "" "" "" 0})
set(gca, 'ytick', 1:6, 'YTickLabels', yticklabels)
title('{\Delta_s - \Delta_c}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 14)
clim([-72 11])
%tile 4
nexttile
imagesc(Slope_BIT_DIF)
%had to change to DeltaSlopeE' in workspace as it was 11x6 not 6x11. 
%xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 10); 
ylabel('{\it β}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12)
xlabel('{\it a}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 12); 
xticklabels({0 "" 0.2 "" 0.4 "" 0.6 "" 0.8 "" 1})
set(gca, 'xtick', 1:11, 'XTickLabel', xticklabels)
yticklabels({1 "" "" "" "" 0})
set(gca, 'ytick', 1:6, 'YTickLabels', yticklabels)
title('{\Delta_s - \Delta_B_I_T}', 'FontWeight', 'bold', 'FontName', 'TimesNewRoman', 'FontSize', 14)
clim([-72 11])
% colorbar
clim([-72 11]) % EDIT THESE LIMITS
cb = colorbar;
cb.Layout.Tile = 'south'
cb.Position = cb.Position + 1e-10;
set(gcf,'PaperSize',[8.5 11])

Thank you in advance :)

You can set colormap for each axes object, like:

% sample data
z = peaks(20);

% display the data with different colormap
tiledlayout(1, 4);
ax1 = nexttile;
imagesc(z)
colormap(ax1, "parula")
colorbar("southoutside")
ax2 = nexttile;
imagesc(z)
colormap(ax2, "hsv")
colorbar("southoutside")
ax3 = nexttile;
imagesc(z)
colormap(ax3, "abyss")
colorbar("southoutside")
ax4 = nexttile;
imagesc(z)
colormap(ax4, "autumn")
colorbar("southoutside")

Thank you. Any idea how to do this with custom made colormaps too?

Yes, you can use your custom colormap in the same way, like:

% sample data
z = peaks(20);

% custom colormap
cMap = [1 0 0; 0 1 0; 0 0 1];

% display the data with different colormap
tiledlayout(1, 4);
ax1 = nexttile;
imagesc(z)
colormap(ax1, "parula")
colorbar("southoutside")
ax2 = nexttile;
imagesc(z)
colormap(ax2, "hsv")
colorbar("southoutside")
ax3 = nexttile;
imagesc(z)
colormap(ax3, "abyss")
colorbar("southoutside")
ax4 = nexttile;
imagesc(z)
colormap(ax4, cMap) % <- custom colormap
colorbar("southoutside")
