I am using Matlab 2018b, I want to plot values above the tips of bars, where:

A=[4, 8 , 20 ,5];
B=[1,3 4 ,8 ];y

I want to write strings above the bars, but when I use XEndPoints, the following message is shown :

No appropriate method, property, or field 'XEndPoints' for class 'matlab.graphics.chart.primitive.Bar'.

my code:

function DisplayBarTopsisSawRankReversal(A,B,...  
                                             X1,X2)
    
    max1= max(A(1,:));
    max2=max(B(1,:));
    MAX=max(max1,max2);
    % This will produce 4 groups of 3 different colored bars
    x = [1 2 ];
    
    
    y = [A;B];
    Bar = bar(x,y);  % h will have 3 handles, one for each color of bars
   
    
    set(Bar, {'DisplayName'}, {'Txt1','Txt2'}');
    legend() ;
    
    
    
    somenames={X1,X2};
    set(gca,'xticklabel',somenames);
    ylabel('Rank Reversal Ratio [%]')
    
    ylim([0 MAX+30]);
    
    
    %text(xtips1,ytips1,string( ) ,'HorizontalAlignment','center','VerticalAlignment','bottom')
    opts = {'VerticalAlign','middle', 'HorizontalAlign','left', ...
        'FontSize',8, 'Rotation',90};
    
    text(1, A(1) ,'s' , opts{:});
    numel(Bar)
    
    xtips2 = b(2).XEndPoints;
end

How can I add strings in my case ?

If you want to put the numbers on the tops of the bars, this works:

    x = [1 2 ];
    y = [A;B];
    figure
    Bar = bar(x,y);  % h will have 3 handles, one for each color of bars                                                       % Return ‘bar’ Handle
%     xtips1 = b(1).XEndPoints;
%     ytips1 = b(1).YEndPoints;
    for k1 = 1:size(A,2)
        ctr(k1,:) = bsxfun(@plus, Bar(k1).XData, Bar(k1).XOffset');       % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
        ydt(k1,:) = Bar(k1).YData;                                        % Individual Bar Heights
    end
   
    for k1 = 1:size(ctr,2)
        text(ctr(:,k1), ydt(:,k1), sprintfc('%d',ydt(:,k1)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
    end

I have no idea what you are doing otherwise, or the result you want.

Make appropriate changes to put whatever you want at the tops of the bars.

The easiest way is to use my code example to put what you want at the tops of the bars. (Use either the undocumented sprintfc or compose to create the appropriate strings.) I have no idea what you want to do with the rest of your code, since I do not understand what you are doing.
