2.2.3 Display

This menu, shown in the figure, contains various options that allow you control the way data are displayed, if at all.

Zoom Out

 

If you've zoomed in on some part of the world map, this button restores the map to cover the whole world. It also restores the time line and the depth range to their original values.

Clear Display

 

This button erases the displayed data from the browser main window.

Reset Display

 

Erases the displayed data from the browser main window, and zooms out to view the whole world, the complete time line, and all depths.

Start Longitude

 

This changes the display map longitude boundaries. Start the longitude at 180W (the international date line) if you want to see the Atlantic, but start at 0E (the greenwich meridian) if you want to see the Pacific entire. This is a toggle switch.
