I finally got the worksheet data to include proper times next to dates and when I chart the data the horizontal axis does not show the date(s); just some type of unit. Researching, I discovered that when I visit Format Selection for the Horizontal (value) axis, the dialog box for Axis Options does not include a group for Axis Type. It is just missing and hence no way to change to Date Axis.
