    xytitles, xtitle, ytitle  


  -or- xytitles, xtitle, ytitle, [deltax,deltay]  
Plot XTITLE horizontally under the viewport and YTITLE vertically  
to the left of the viewport.  If the tick numbers interfere with  
the labels, you can specify the [DELTAX,DELTAY] in NDC units to  
displace the labels.  (Especially for the y title, the adjustment  
may depend on how many digits the numbers on your scale actually  
have.)  Note that DELTAX moves YTITLE and DELTAY moves XTITLE.  
WARNING: There is no easy way to ensure that this type of title  
         will not interfere with the tick numbering.  Interference  
         may make the numbers or the title or both illegible.
