filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/965825/advancedstats2.csv';
t = readtable(filename);
t.Properties.VariableNames

ans = 1×4 cell array
    {'subj'}    {'group'}    {'trial'}    {'logmIKI'}

G = findgroups(t.group);
output = splitapply(@(subj, group, trial, logmIKI) {table(subj, group, trial, logmIKI)}, t, G)

output = 3×1 cell array
    {6480×4 table}
    {6480×4 table}
    {3600×4 table}

output{1}(1:10,:)

ans = 10×4 table
    subj    group    trial    logmIKI
    ____    _____    _____    _______

     38       0        1         NaN

Exactly what are you trying to plot? What are the x values, and the y values?

You can't just string together three parentheses expressions like that

stackedplot ((output{1}(1:6480,:)(output{2}(1:6480,:)(output{1}(1:3600,:))

Try assigning each to some variable:

y1 = output{1}(1:6480,:)
y2 = output{2}(1:6480,:)
y3 = output{3}(1:3600,:)

Then use in stackedplot() and be sure to use commas between separate arguments.

stackedplot() does not offer any way to plot with different sizes of variables.
