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

  FT_SINGLEPLOTER plots the event-related fields or potentials of a single
  channel or the average over multiple channels. Multiple datasets can be
  Use as
    ft_singleplotER(cfg, data)
    ft_singleplotER(cfg, data1, data2, ..., datan)
  The data can be an erp/erf produced by FT_TIMELOCKANALYSIS, a power
  spectrum produced by FT_FREQANALYSIS or connectivity spectrum produced by
  The configuration can have the following parameters:
    cfg.parameter     = field to be plotted on y-axis (default depends on data.dimord)
                        'avg', 'powspctrm' or 'cohspctrm'
    cfg.maskparameter = field in the first dataset to be used for masking of data
                        (not possible for mean over multiple channels, or when input contains multiple subjects
                        or trials)
    cfg.maskstyle     = style used for masking of data, 'box', 'thickness' or 'saturation' (default = 'box')
    cfg.xlim          = 'maxmin' or [xmin xmax] (default = 'maxmin')
    cfg.ylim          = 'maxmin', 'maxabs', 'zeromax', 'minzero', or [ymin ymax] (default = 'maxmin')       = nx1 cell-array with selection of channels (default = 'all')
                        see ft_channelselection for details
    cfg.title          = string, title of plot
    cfg.refchannel    = name of reference channel for visualising connectivity, can be 'gui'
    cfg.baseline      = 'yes', 'no' or [time1 time2] (default = 'no'), see ft_timelockbaseline
    cfg.baselinetype  = 'absolute' or 'relative' (default = 'absolute')
    cfg.trials        = 'all' or a selection given as a 1xn vector (default = 'all')
    cfg.fontsize      = font size of title (default = 8)
    cfg.hotkeys       = enables hotkeys (leftarrow/rightarrow/uparrow/downarrow/m) for dynamic zoom and translation (ctrl+) of the axes
    cfg.interactive   = interactive plot 'yes' or 'no' (default = 'yes')
                        in a interactive plot you can select areas and produce a new
                        interactive plot when a selected area is clicked. multiple areas
                        can be selected by holding down the shift key.
    cfg.renderer      = 'painters', 'zbuffer', ' opengl' or 'none' (default = [])
    cfg.linestyle     = linestyle/marker type, see options of the PLOT function (default = '-')
                        can be a single style for all datasets, or a cell-array containing one style for each dataset
    cfg.linewidth     = linewidth in points (default = 0.5)
    cfg.graphcolor    = color(s) used for plotting the dataset(s) (default = 'brgkywrgbkywrgbkywrgbkyw')
                        alternatively, colors can be specified as nx3 matrix of rgb values
    cfg.directionality = '', 'inflow' or 'outflow' specifies for
                        connectivity measures whether the inflow into a
                        node, or the outflow from a node is plotted. The
                        (default) behavior of this option depends on the dimor
                        of the input data (see below).
  For the plotting of directional connectivity data the cfg.directionality
  option determines what is plotted. The default value and the supported
  functionality depend on the dimord of the input data. If the input data
  is of dimord 'chan_chan_XXX', the value of directionality determines
  whether, given the reference channel(s), the columns (inflow), or rows
  (outflow) are selected for plotting. In this situation the default is
  'inflow'. Note that for undirected measures, inflow and outflow should
  give the same output. If the input data is of dimord 'chancmb_XXX', the
  value of directionality determines whether the rows in data.labelcmb are
  selected. With 'inflow' the rows are selected if the refchannel(s) occur in
  the right column, with 'outflow' the rows are selected if the
  refchannel(s) occur in the left column of the labelcmb-field. Default in
  this case is '', which means that all rows are selected in which the
  refchannel(s) occur. This is to robustly support linearly indexed
  undirected connectivity metrics. In the situation where undirected
  connectivity measures are linearly indexed, specifying 'inflow' or
  'outflow' can result in unexpected behavior.
  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.
