Access 2007 Chart

[vbd00d]

Hello all, I have a table that I would like to chart. The table is formatted like this:

Date---Measured---Low---Medium---High
12/01/08 8:00 AM---.75---.65---.85---.95
12/01/08 8:30 AM---.73---.65---.85---.95
12/01/08 9:00 AM---.78---.65---.85---.95
12/01/08 9:30 AM---.65---.65---.85---.95
12/01/08 10:00 AM---.75---.65---.85---.95

I would like to chart the Measured, Low, Medium, and High values and have the date on the bottom axis (shown increments of every 30 minutes.) How can I do this? I have tried, and always seem to get weird increments.
