FindDivisions

FindDivisions[{xmin,xmax},n] finds a list of about n "nice" numbers that divide the interval around xmin to xmax into equally spaced parts. 

FindDivisions[{xmin,xmax,dx},n] makes the parts always have lengths that are integer multiples of dx. 

FindDivisions[{xmin,xmax},{n1,n2,…}] finds successive subdivisions into about n1, n2, … parts. 

FindDivisions[{xmin,xmax,{dx1,dx2,…}},{n1,n2,…}] uses spacings that are forced to be multiples of dx1, dx2, ….
