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

  FT_TOPOPLOTCC plots the coherence between channel pairs
 
  Use as
   ft_topoplotCC(cfg, freq)
 
  The configuration should contain:
    cfg.feedback    = string (default = 'textbar')
    cfg.layout      = specification of the layout, see FT_PREPARE_LAYOUT
    cfg.foi         = the frequency of interest which is to be plotted (default is the first frequency bin)
    cfg.widthparam  = string, parameter to be used to control the line width (see below)
    cfg.alphaparam  = string, parameter to be used to control the opacity (see below)
    cfg.colorparam  = string, parameter to be used to control the line color
 
  The widthparam should be indicated in pixels, e.g. usefull numbers are 1
  and larger.
 
  The alphaparam should be indicated as opacity between 0 (fully transparent)
  and 1 (fully opaque).
 
  The default is to plot the connections as lines, but you can also use
  bidirectional arrows:
     cfg.arrowhead    = string, 'none', 'stop', 'start', 'both' (default = 'none')
     cfg.arrowsize    = scalar, size of the arrow head in figure units,
                        i.e. the same units as the layout (default is automatically determined)
     cfg.arrowoffset  = scalar, amount that the arrow is shifted to the side in figure units,
                        i.e. the same units as the layout (default is automatically determined)
     cfg.arrowlength  = scalar, amount by which the length is reduced relative to the complete line (default = 0.8)
 
  To facilitate data-handling and distributed computing you can use
    cfg.inputfile   =  ...
  If you specify this option the input data will be read from a *.mat
  file on disk. This mat files should contain only a single variable named 'data',
  corresponding to the input structure. For this particular function, the input should be
  structured as a cell array.
