A table variable? Use the table() function.

A uitable spreadsheet control on your gui? Set the data property of your control to your cell array of strings.

handles.uitable1.Data = myCellArray;

First convert your matrix to a table and use the variable names in your cell array.

T = array2table(x, 'VariableNames', varNameArray); 
stackedplot(T)

Also see the DisplayLabels property.

I would suggest counting the unique times, then you can split up the table based on the counts:

d = datetime(2018,1,1,[1 2 4 4 2 1 2 3 4  4]',0,0);
t = table(d,rand(size(d)),'VariableNames',["time","data"]);
[C, ia, ic] = unique(t.time,'stable');
d_counts = accumarray(ic,1)
% expand the counts back out to the height of the table
d_counts = d_counts(ic)
t.counts = d_counts;
% split up the table
t_1 = t(t.counts == 1,:)
%...

That said, do you really need to split up the table? Labeling variables numerically like that is usually a sign that you're heading down a path to breakable code. Now that you have the counts in your table, you can dynamically subscript into t and temporarily get the subset that you need. Or, use groupsummary or grouped varfun to apply functions to the whole table, grouped by count.
