 mag_rate_stream::get_yscale
        Return the "natural" Y-scaling for a mag stream.

 Usage:
        scale = strref -> get_scaling(<keys>)

 Keywords:
        zero            If set, then return zeros rather than NaNs when no
                        data are present.
        sector          If set, then return extrema for the sectors
                        separately.
        only            If set, then only return extrema for the specified
                        sector (or NaN if the sector is not present).
        positive        If set, then use min_nz instead of min to give a
                        positive-definite range
        tickvals        A named variable to contain the tick values to use
        minor           A named variable to contain the number of minor tick
                        to use.
        logarithmic     If set then return if this should be plotted
                        on a log scale (should always be 0).

 Notes:
        For most streams, this is just a wrapper for the get_extrema
        method, with an _extra key swallower.
