graduate - pretty axis graduations
.SH CALLING SEQUENCE
.nf
[xi,xa,np]=graduate( xmi, xma,n1,n2)	
[xi,xa,np]=graduate( xmi, xma)
.fi
.SH PARAMETERS 
.TP 10
xmi,xma
: real scalars
.TP

.SH DESCRIPTION
graduat looks for the minimum interval \fV[xi,xa]\fR and a number of tics 
\fVnp\fR such that:
.LP
\fVxi <= xmi <= xma <= xa\fR
.LP
\fVxa - xi / np  =  k(10^n)\fR,\fVk\fR in \fV[1 3 5]\fR  for an integer \fVn\fR
.LP
\fVn1 < np < n2\fR
