Provide the complete file path to ‘DAH.xlsx’ . That is easiest to do with the fullfile function.

I cannot determine that because I do not know what the first column is. I also do not know what version/release of MATLAB you have.
One option, to be safe, is to to use the datenum function to convert the times to date numbers. Those values should plot correctly.
(A better approach would be to use datetime, and perhaps readtable or readmatrix instead of xlsread, however I do not know if you have those options.)
