The graphical displays have several features in common. Commands are selected from buttons and menus ranged along the top of the window. Menus can be "torn off" and positioned anywhere on the screen. Zooming is allowed using the mouse. The "Zoom out" button undoes the previous zoom command. Crosshairs and cursors can be toggled on and off, and their coordinates in base positions appear in boxes in the top right hand corner of the displays. Items plotted in the graphical displays have text attached, and as the cursor passes over an item, it is highlighted and its text appears in an Information line at the bottom of the display.
