I have uit.Data and i want to use "stackedplot" for display the information from the table.
I want to plot below table x & y coordinates.
where x for WeirdDuration and y for text data

While it's fairly straightforward to plot table data using the line below, I don't think adding text is supported.
To add text, you would need to supply the axes handle in order to specify which axes the test should be added to but stackedplot does not return axis handles so there's no way (I know of) to add things to a stakedplot axes. It's a fairly new feature (r2018b) so maybe that functionality will be added in the future.
Instead, I recommend creating your own subplot axes and use linkaxes to link the axis ranges. The vertical line won't appear but you could add grids so it's easy to visually compare subplots.

I'm assuming you're positioning text according to this screen shot you shared in an earlier question. Since text cannot currently be added to stackedplot axes (as for r2019b, let's hope that changes), here's a way to customize your own axes and link their x-axis limits, and then add text to each axes.
Please follow this demo and the inline comments for more detail.
% Create input table for demo because OP did not provide table
T = table((duration(0,0,17):seconds(1):duration(0,0,20))',...
% The only input would be "T", the table created above. It is assumed that
% The x values are stored in the first column named 'WeirdDuration' and that
% a subplot should be created for each subsequent column in T.
% Create figure with linked subplots stacked vertically
fig = figure();
nSub = size(T,2)-1; %number of subplots assuming 1 subplot for each col of T except the first
% in order to maximize spaces, create subplots manually.
margins = [.11 .11 .08 .12 .01]; %margins: left, right, bottom, top, vertical space between plots
height = (1-sum(margins(3:4)) - (nSub-1)*margins(5))/nSub; %height of each subplot
width = 1-sum(margins(1:2)); % width of each subplot
subPos = margins(3):height+margins(5):1; %vertical position of each subplot from bottom to top (may have extra values at end)
subHand = arrayfun(@(i)axes(fig,'Position',[margins(1),subPos(i),width,height]),1:nSub);
% add grids
set(subHand,'XGrid','on') % you could add 'YGrid','on' if you wish
% How loop through each subplot (i) and add text from column i+1
x = T.WeirdDuration; % the x coordinates of your text
y = 1:size(T,1); % the y coordinates of your text
for i = 1:nSub
th = text(subHand(i), x, y, T{:,i+1},'VerticalAlignment','Bottom');
xlim(subHand(i),[min(x),max(x)+range(x)*.1]) %adds 10% of axis range
% Link x axes so the x limits are always the same
% Remove x tick for all but bottom axes
set(subHand(2:end),'XTickLabel', [])

"I would request your help with your code under (PlotButton)"
Sure's what's your question?

This topic is a lot different from your original question. Has your original question been answered?
Regarding the scroll bar, it looks like your UITable already has a vertical and horizontal scroll bar so I'm not sure what you're looking for.

What do you expect to see with your text data in the plot?
stackedplot ignores text data, but plots categorical data. If your text data can be converted into categorical (contains only a relatively small number of choices), you should convert and then plot. There is a convertvars function that can do the conversion for you.
