MATLAB: How to flip heatmap Y axis

datagraphMATLAB

Hi all,

I am creating a heatmap based on a table with x and z coordinate and the parameter value for each position. I copy here an image of the table.

The command I am using to create the heatmap is this one:

figure = heatmap(table,'x','z','ColorVariable','value');

And the heatmap created is this one.

Question

Does anybody know how could I flip the z values to show the '0' value at the bottom of the heatmap and the value '0.022' at the top instead of the opposite?

Thanks in advance

hHM=heatmap(table,'x','z','ColorVariable','value');  % make heatmap, keep handle
hHM.NodeChildren(3).YDir='normal';                   % turn Y-Axis normal direction

Yet another case where TMW has gotten far too clever and hidden the useful/needed properties for some reason only they can divine...

MATLAB: Is there a way to define a default axis position, similar to defaultFigurePosition

Yes.

% A strange small size to be sure, that it works:
set(groot, 'defaultAxesPosition', [0.25, 0.25, 0.2, 0.2])
figure;
plot(1:10)

This is a bad idea, because it modifies all folling axes objects. It is smarter to do this for your own figures only:

% Reset the stuff from above:
set(groot, 'defaultAxesPosition', get(groot, 'factoryAxesPosition'))
figure('defaltAxesPosition', [0.55, 0.55, 0.2, 0.2])
plot(1:10)

Using 0 as root object is outdated since 2014. Prefer groot.
