Using data frame properties to fine-tune map canvas display
In ArcMap (at all license levels of ArcGIS), the data frame controls how data is displayed on the map canvas. The Data Frame Properties dialog box has Coordinate System, Illumination, Grids, Map Cache, Frame, Size and Position, Annotation Groups, Extent Rectangles, General, and Data Frame tabs. The Data Frame tab holds several tools, some old, one new. The Extent, Clip to Shape, and Extent Used by Full Extent Command tools control how map viewers see and interact with a map.
