THIS WORKS:

ColTitles = {'S/N' 'ATTENUATION(dB)'  'MONTH'};
DataCell = {1  12     'JANUARY,2011'
            2  17     'FEBRUARY,2011'
            3  18     'MARCH,2011'
            4  14     'APRIL,2011'
            5  11     'MAY,2011'
            6  08     'JUNE,2011'
            7  18     'JULY,2011'};

Mos = datetime(DataCell(:,3), 'InputFormat', 'MMMM,yyyy');
AttdB = cell2mat(DataCell(:,2));

figure(1)
plot(Mos, AttdB, ':bp')
grid
xlabel(ColTitles{3})
ylabel(ColTitles{2})
