Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_connectivityplot”.

  FT_CONNECTIVITYPLOT plots channel-level frequency resolved connectivity. The
  data are rendered in a square grid of subplots, each subplot containing the
  connectivity spectrum between the two respective channels.
  Use as
    ft_connectivityplot(cfg, data)
  The input data is a structure containing the output to FT_CONNECTIVITYANALYSIS
  using a frequency domain metric of connectivity. Consequently the input
  data should have a dimord of 'chan_chan_freq', or 'chan_chan_freq_time'.
  The cfg can have the following options:
    cfg.parameter   = string, the functional parameter to be plotted (default = 'cohspctrm')
    cfg.xlim        = selection boundaries over first dimension in data (e.g., freq)
                      'maxmin' or [xmin xmax] (default = 'maxmin')
    cfg.ylim        = selection boundaries over second dimension in data
                      (i.e. ,time, if present), 'maxmin', or [ymin ymax]
                      (default = 'maxmin')
    cfg.zlim        = plotting limits for color dimension, 'maxmin', 'maxabs' or [zmin zmax] (default = 'maxmin')     = list of channels to be included for the plotting (default = 'all'), see FT_CHANNELSELECTION for details
