    """Plot calibration solutions:

        An all-purpose plotter for calibration results.  The values for all

    calibration solutions (G, T, GSPLINE, B, BPOLY, D) can be displayed

    for a variety of polarization combinations and calibrations.  The

    solutions may be iterated through antennas/spw/fields during one execution.

​

    The plotter permits zooming, listing and flagging of solutions, although

    the implications of flagged solutions are not yet made.

​

    Keyword arguments:

    caltable -- Name of input calibration table 

        default: none; example: caltable='ngc5921.gcal'

            The type of calibration table is determined automatically.

    xaxis -- Value to plot on the x axis

        Options: 'time','chan','freq','antenna','amp','phase','real','imag','snr'

        Default: cal type dependent, usually 'time'

    yaxis -- Value to plot ong the y-axis

        Options: 'amp','phase','real','imag','snr','antenna'

        Default: cal type dependent, usually 'amp'

    poln -- Polarization (or combination) to plot

            default: '' (RL); all polarizations

        Options: '' = ('RL'),'R','L','XY','X','Y',

                       '/' --> form complex poln ratio

                         (amp ratio and phase difference)

    field -- Select field using field id(s) or field name(s).

                  ['go listobs' to obtain the fieldt id's or names]

               default: ''=all fields

               If field string is a non-negative integer, it is assumed a

           field index, otherwise it is assumed a field name

               field='0~2'; field ids 0,1,2

               field='0,4,5~7'; field ids 0,4,5,6,7

               field='3C286,3C295'; field named 3C286 and 3C295

               field = '3,4C*'; field id 3, all names starting with 4C

    antenna -- Antenna selection (baseline syntax ignored)

               default: '' (all);

               example: antenna='1,3~5' means antenna

                  indices 1,3,4,5.  

    spw -- Select spectral window (channel syntax ignored, except for D)

               default: ''=all spectral windows

               spw='0~2,4'; spectral windows 0,1,2,4

               spw='<2';  spectral windows less than 2

    timerange -- Time selection

                  default: '' (all)

          example: timerange='1995/04/13/09:15:00~1995/04/13/09:25:00'
