How can I plot a bar char from an excel file?

I wan to plot a bar chart like the attached picture from the attached excel file sample. The problem is that I can not use the first column as ticks. It is shown by numbers.I tried some other techniques but it did not work since all the letter were not shown on the plot. I would be thankful if someone could help me. Thanks!

csvfiles = dir('*.csv');

for file = csvfiles'

T = readtable(file.name) ;

A = table2array(T(2:end,2:end)) ;

l = T.(1) ;

bar(A)

end

Try the following:

T = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1276650/Sample.csv');
X = categorical(T.Var1);                    % Convert to categorical
Y = table2array(T(:,2:3));
bar(X,Y)
