• Server - Selects the server to be used. Enter in a server name or choose one from the pulldown menu.
• Manage - Manages the list of servers by opening the ADDE Servers tab of the User Preferences window.
• Dataset - Represents the dataset being used. Enter in a dataset name or choose one from the pulldown menu.
• Public Servers - Lists the public datasets available on the server.

• Point Type - Selects the Point Type to display.
• Times: Relative - Allows you to select a group of up to the last 100 times, for the current date only.
• Relative Time Increment - Sets a time increment to use with relative times. For example, using "3 most recent" times with a "3" hour time increment would result in the most recent time, one from 3 hours ago and one from 6 hours ago.
• Times: Absolute - Allows you to choose one or more absolute times. When choosing absolute times for the first time McIDAS-V needs to query the ADDE server for the times. This may take some time. To select more than one time use Ctrl+click or Shift+click. See the Timeline Controls section for details on its use. Click on the Select Day button to narrow down a large dataset to one day.
• Interval - Selects the time interval to use when displaying this data.
• Help - Brings up this help page.
