Is it possible to create a horizontal axis that contains large tick marks that denote days (Ex: 10/20/2009, 10/21/2009, etc) and in between each day you would have smaller tick marks to denote hours (Ex: 8:00 am, 9:00 am, etc). So there would be 24 hours in each day. I can get it to do one or the other but not both.
