Hello! I would like the colorbar label to appear directly underneath the colorbar (right underneath the "220" in the figure below), horizontal along the x axis. However, when I specify this as follows, it aligns the label along the y axis.

Here is the relevant code:

contourf(lon,lat,tmp2, 25, 'LineStyle','none');

hold on

colormap('turbo')

set(gca,'fontsize',14);

ylabel('Latitude (\circ)')

xlabel('Longitude (\circ)')

h = colorbar;

xlabel(h,'(K)');

hold off

------

can someone help me change the orientation of that '(K)', and show me how to adjust my code in general so I can make this adjustments in other plots as well? Thanks.

在 MATLAB Online 中打开

% generate random data:

lon = 0:359;

lat = -90:90;

tmp2 = 217+96*rand(numel(lat),numel(lon));

contourf(lon,lat,tmp2, 25, 'LineStyle','none');

colormap('turbo')

set(gca,'fontsize',14);

ylabel('Latitude (\circ)')

xlabel('Longitude (\circ)')

h = colorbar;

xlabel(h,'(K)');

h.Label.Units = 'normalized';

h.Label.Position = [2 0]; % more-or-less centered under the colorbar tick labels

h.Label.Rotation = 0;

Alternatively, you can use

h.Label.Position = [0.5 0]; % centered under the colorbar itself

to center the colorbar label under the colorbar itself, or adjust the first element (or both elements) of that Position as desired.

Position is [x,y] and Units are normalized to the colorbar itself, so [0 0] would place the label at the lower-left of the colorbar, [1 1] would place it at the upper-right, [0 1] would be upper-left, and [1 0] would be lower-right. The label has VerticalAlignment 'top' and Horizontalignment 'center', so the Position is where the top center of the label will be located.
