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

  FT_PLOT_BOX plots the outline of a box that is specified by its lower
  left and upper right corner
 
  Use as
    ft_plot_box(position, ...)
  where the position of the box is specified as is [x1, x2, y1, y2].
 
  Optional arguments should come in key-value pairs and can include
    'facealpha'       = transparency value between 0 and 1
    'facecolor'       = color specification as [r g b] values or a string, for example 'brain', 'cortex', 'skin', 'red', 'r'
    'edgecolor'       = color specification as [r g b] values or a string, for example 'brain', 'cortex', 'skin', 'red', 'r'
    'tag'             = string, the name assigned to the object. All tags with the same name can be deleted in a figure, without deleting other parts of the figure.
 
  It is possible to plot the object in a local pseudo-axis (c.f. subplot), which is specfied as follows
    'hpos'            = horizontal position of the center of the local axes
    'vpos'            = vertical position of the center of the local axes
    'width'           = width of the local axes
    'height'          = height of the local axes
    'hlim'            = horizontal scaling limits within the local axes
    'vlim'            = vertical scaling limits within the local axes
    'parent'          = handle which is set as the parent for all plots
 
  Example
    ft_plot_box([-1 1 2 3], 'facecolor', 'b')
    axis([-4 4 -4 4])
