Plot Cell
This will plot the entire extents of the current cell - (even if you are zoomed into a portion of the cell).
Plot View
This will plot your current view - exactly what you see on the screen. The PLOT UPI picks up the screen extents from an L-Edit function call...
Plot Window
This will enable you to use the mouse to define a window within the area that is already displayed. The corners of the window will determine what is plotted.
