 height=                height in pixels of window			
 nTic1=                 number of tics per numbered tic on axis 1

 nTic2=                 number of tics per numbered tic on axis 2	
 grid2=                 grid lines on axis 2 - none, dot, dash, or solid
 label2=                label on axis 2				
 labelFont=             font name for axes labels			
 title=                 title of plot					
 titleFont=             font name for title				
 titleColor=            color for title				
 axesColor=             color for axes					
 gridColor=             color for grid lines				
 style=                 normal (axis 1 horizontal, axis 2 vertical) or	
                        seismic (axis 1 vertical, axis 2 horizontal)	
 sleep=                 delay between frames in microseconds           

 Color options:                                                        
 cmap=gray     gray, hue, saturation, or default colormaps may be specified
 bhue=0        hue mapped to bclip (hue and saturation maps)		
 whue=240      hue mapped to wclip (hue and saturation maps)		
 sat=1         saturation (hue map only)				
 bright=1      brightness (hue and saturation maps)			
 white=(bclip+wclip)/2  data value mapped to white (saturation map only)

 Notes:								
 Colors are specified using the HSV color wheel model:			
   Hue:  0=360=red, 60=yellow, 120=green, 180=cyan, 240=blue, 300=magenta
   Saturation:  0=white, 1=pure color					
   Value (brightness):  0=black, 1=maximum intensity			
 For the saturation mapping (cmap=sat), data values between white and bclip
   are mapped to bhue, with saturation varying from white to the pure color.
   Values between wclip and white are similarly mapped to whue.	
 For the hue mapping (cmap=hue), data values between wclip and bclip are
   mapped to hues between whue and bhue.  Intermediate hues are found by
   moving counterclockwise around the circle from bhue to whue.  To reverse
   the polarity of the image, exchange bhue and whue.  Equivalently,	
   exchange bclip and wclip (setting perc=0 is an easy way to do this).
   Hues in excess of 360 degrees can be specified in order to reach the
   opposite side of the color circle, or to wrap around the circle more
   than once.								

 The title string may contain a C printf format string containing a	
   conversion character for the frame number.  The frame number is	
   computed from dframe and fframe.  E.g., try setting title="Frame %g".
