octave: Marker Styles

 
 15.4.3 Marker Styles
 --------------------
 
 Marker styles are specified by the following properties:
 
 ‘marker’
      A character indicating a plot marker to be place at each data
      point, or "none", meaning no markers should be displayed.
 
 ‘markeredgecolor’
      The color of the edge around the marker, or "auto", meaning that
      the edge color is the same as the face color.  SeeColors.
 
 ‘markerfacecolor’
      The color of the marker, or "none" to indicate that the marker
      should not be filled.  SeeColors.
 
 ‘markersize’
      A number specifying the size of the marker.  The default is 1.  A
      value of 2 is twice as large as the default, etc.
 
    The ‘colstyle’ function will parse a ‘plot’-style specification and
 will return the color, line, and marker values that would result.
 
  -- : [STYLE, COLOR, MARKER, MSG] = colstyle (LINESPEC)
      Parse LINESPEC and return the line style, color, and markers given.
 
      In the case of an error, the string MSG will return the text of the
      error.
