I need a bar graph like the picture given below for these values with colorjet. The points (1,0), (1,0.1), (1,0.2), (1,0.3), (1,0.4) and (1,0.5) with values respectively 0.725, 0.654, 0.543, 0.812, 0.698 and 0.456 And The points (2,0), (2,0.1), (2,0.2), (2,0.3), (2,0.4) and (2,0.5) with values respectively 0.628, 0.652, 0.783, 0.682, 0.758 and 0.765.

Would this work for you?
thickness = ones(2,6)*0.1;
vals = [0.725, 0.654, 0.543, 0.812, 0.698, 0.456;
0.628, 0.652, 0.783, 0.682, 0.758, 0.765];
figure;
hb = barh(thickness ,'BarLayout','stacked','FaceColor','flat');
cmap = jet(256);
for i = 1:6
hb(i).CData = cmap(round(vals(:, i)*256),:);
end
cbar = colorbar;
ylabel(cbar, "Transmittance")
colormap(cmap);
xlabel("Thickness");
ylabel("Structure");

You can use "bar" instead of "barh" to swap X and Y axis.
Also, do not forget to change xlabel and ylabel too.
