cfplot.gvals(dmin=None, dmax=None, mystep=None, mod=True)

gvals - work out a sensible set of values between two limits

This is an internal routine used for contour levels and axis

labelling and is not generally used by the user.

dmin = None - minimum

dmax = None - maximum

mystep = None - use this step

mod = True - modify data to make use of a multipler
