How to change x-axis ticks labels in stackedplot?

h = stackedplot(rand(6,3));

I want to set x-axis ticks according to my own defined set i.e., instead of 1:6, I want to replace x-axisticks [1, 2,3 ,4,5,6] to ['A', 'S','T', 'AAA', 'BBB', 'ZZZ'] , by rotating it to 90 degree that is vertically insted of horizontally?

There does not seem to be an easy way to set the XTick or XTickLabel of a StackedLineChart object (such as what's created by stackedplot):

data = rand(6,3);
h = stackedplot(1:6,data);

% try a couple of things, neither of which work
try
    set(h,'XTick',1:6,'XTickLabel',{'A' 'S' 'T' 'AAA' 'BBB' 'ZZZ'})
catch ME
    disp(['Cannot use set(_,''XTick''): ' ME.message]);
    try
        xticks(h,1:6)
    catch ME
        disp(['Cannot use xticks(_): ' ME.message]);
    end
end

Cannot use set(_,'XTick'): Unrecognized property XTick for class StackedLineChart.

Cannot use xticks(_): Using xticks with stackedplot is not supported.

However, you can do it if you use tiledlayout (or subplot):

figure();
tiledlayout(3,1,'TileSpacing','tight');

for i = [1 2 3]
    ax = nexttile;
    plot(data(:,i));
    box off
    if i < 3
        set(get(ax,'XAxis'),'Visible','off');
    end
    ylabel(ax,sprintf('Column %d',i), ...
        'Rotation',0, ...
        'HorizontalAlignment','right');
end

% now ax is the bottom axes
set(ax, ...
    'XTick',1:6, ...
    'XTickLabel',{'A','S','T','AAA','BBB','ZZZ'}, ...
    'XTickLabelRotation',90);

@Ammy You're welcome!

Use xtick and xticklabels to change to the A, S, T, ... labels

I don't understand what you further mean with the rotating 90° though.

No you can not use it when you use stackedplot.

that's really annoying

There is a quicker method that worked for me using NodeChildren in MATLAB2021b.

h = stackedplot(rand(6,3));

ax = findobj(h.NodeChildren, 'Type','Axes');

set(ax,'XTick',[1:6],'XTickLabel',{'A', 'S','T', 'AAA', 'BBB', 'ZZZ'})
