Convert collumn 1 to a datetime and then just use the plot command. See Ch 9 of MATLAB Onramp if you need more help with plotting.

d = datetime(40560.29167,'ConvertFrom','excel','Format','M/d/yyyy HH:mm')

d = datetime

1/17/2011 07:00

plot(d,101.745,'ro')

You wouldn't use a loop. You would use a variable contining all your values.

Share the code you've written so far and we can go from there.
