  FT_SINGLEPLOTTFR plots the time-frequency representation of power of a
  single channel or the average over multiple channels.
  Use as
  The input freq structure should be a a time-frequency representation of
  power or coherence that was computed using the FT_FREQANALYSIS function.
  The configuration can have the following parameters:
    cfg.parameter      = field to be plotted on z-axis, e.g. 'powspcrtrm' (default depends on data.dimord)
    cfg.maskparameter  = field in the data 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 to masking, 'opacity', 'saturation' or 'outline' (default = 'opacity')
                         use 'saturation' or 'outline' when saving to vector-format (like *.eps) to avoid all sorts of image-problems
    cfg.maskalpha      = alpha value between 0 (transparant) and 1 (opaque) used for masking areas dictated by cfg.maskparameter (default = 1)
    cfg.masknans       = 'yes' or 'no' (default = 'yes')
    cfg.xlim           = 'maxmin' or [xmin xmax] (default = 'maxmin')
    cfg.ylim           = 'maxmin' or [ymin ymax] (default = 'maxmin')
    cfg.zlim           = plotting limits for color dimension, 'maxmin', 'maxabs', 'zeromax', 'minzero', or [zmin zmax] (default = 'maxmin')
    cfg.baseline       = 'yes','no' or [time1 time2] (default = 'no'), see FT_FREQBASELINE
    cfg.baselinetype   = 'absolute', 'relative', 'relchange' or 'db' (default = 'absolute')
    cfg.trials         = 'all' or a selection given as a 1xN vector (default = 'all')        = Nx1 cell-array with selection of channels (default = 'all'),
                         see FT_CHANNELSELECTION for details
    cfg.refchannel     = name of reference channel for visualising connectivity, can be 'gui'
    cfg.fontsize       = font size of title (default = 8)
    cfg.hotkeys           = enables hotkeys (up/down arrows) for dynamic colorbar adjustment
    cfg.colormap       = any sized colormap, see COLORMAP
    cfg.colorbar       = 'yes', 'no' (default = 'yes')
    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.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.
