cfplot._gvals(dmin=None, dmax=None, mystep=None, mod=True)[source]#: Work out a sensible set of values between two limits.

This is an internal routine used for contour levels and axis

dmin = None - minimum

dmax = None - maximum

mystep = None - use this step

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