But you can quite easily combine your three files into a single one, if 
you've collected some needful tools about your work place.  Using the 
usual Unix tools, e.g., it would be as simple as:

	plot '< paste file1 file2 file3'

For more complex, use 'join' instead of 'paste', or write yourself a 
little data processing script.  And it may be preferrable to do it once, 
instead of each time you need a fresh plot:

	! paste file1 file2 file2 > files_1_2_3
