plot x axis with date string from cell array

Hi, I am plotting a graph with x-axis with date string in this format ('12/19/16 0:00', '12/20/16 10:30'). X-axis values are stored in 47040 * 1 cell array, and I picked representative 5 values to put on X-axis. However, it only outputs first value of an array.

Do you see why it is printing this way?

 figure;
 for k=1:7
    diffSum = 0;
    for i=(1+(k-1)*size(c,1)):(k*size(c,1))
        diff = CumDiff(:,i);
        diffSum = diffSum+ diff;
    end
    legend('-DynamicLegend');
    plot(diffSum, 'color', rand(1,3), 'LineWidth', 3, 'DisplayName', sprintf('Group Thermal Comfort: %d', tc(k)));hold on;
    legend('show');
    drawnow;
end
xtickangle(45);
set(gca,'Xtick',1:10000:47040);
set(gca,'XtickLabel',datestr(out{1,1}(1:10000:47040)));

Try

set(gca, 'XtickLabel', cellstr( datestr(out{1,1}(1:10000:47040)) ) );

Thank you for the comment. But I still get the one value only. Strangely, if I provide an array with values, it prints all the values to (0,0). How should I fix my code?

set(gca, 'XtickLabel', ['12/19/16 0:00',    '12/20/16 10:30',    '12/21/16 23:15',    '12/23/16 10:00',    '12/24/16 22:45'] );

 set(gca, 'XtickLabel', {'12/19/16 0:00',    '12/20/16 10:30',    '12/21/16 23:15',    '12/23/16 10:00',    '12/24/16 22:45'} );

Remember, ['A', 'B'] for char means the same as ['AB'] which is 'AB'

The cellstr() was there to convert the char array produced by datestr() into a cell array of strings.
