[PARAMETERS]
string  | bar | = |   | 	file for scalebar data 
bool    | barreverse | =n |  [y/n] | 	if y, go from small to large on the bar scale 
string  | color | = |   | 	color scheme (default is i) 
int     | dframe | =1 |   | 	frame increment in a movie 
bool    | flat | =y |  [y/n] | 	if n, display perspective view 
int     | frame1 | =0 |   | 	top frame number 
int     | frame2 | =n2-1 |   | 	side frame number 
int     | frame3 | =0 |   | 	front frame number 
float   | maxval | = |   | 	maximum value for scalebar (default is the data maximum) 
float   | minval | = |   | 	minimum value for scalebar (default is the data minimum) 
int     | movie | =0 |   | 	0: no movie, 1: movie over axis 1, 2: axis 2, 3: axis 3 
int     | n1pix | =n1/point1+n3/(1.-point1) |   | 	number of vertical pixels 
int     | n2pix | =n2/point2+n3/(1.-point2) |   | 	number of horizontal pixels 
int     | nreserve | =8 |   | 	reserved colors 
float   | point1 | =0.5 |   | 	fraction of the vertical axis for front face 
float   | point2 | =0.5 |   | 	fraction of the horizontal axis for front face 
bool    | scalebar | =n |  [y/n] | 	if y, draw scalebar
