str = string(dtm) % string array
txt = cellstr(dtm) % cell array of character vectors

I want to put xticklabels.

If you're plotting using this datetime data as one of the inputs in your call to plot, the tick labels will automatically be generated from the plotted datetime array. You don't need to convert to a string array in this case.

v = 0:10;

x = datetime('today') + days(v);

y = v.^2;

plot(x, y)
