; The purpose of cgOPlot is to create a drop-in replacement for the traditional
; IDL command, OPlot. It simply calls cgPlot with the OVERPLOT keyword set.
;
; The program requires the `Coyote Library <http://www.idlcoyote.com/documents/programs.php>`
; to be installed on your machine.
;
; :Categories:
; Graphics
;
; :Params:
; x: in, required, type=any
; If X is provided without Y, a vector representing the dependent values to be
; plotted If both X and Y are provided, X is the independent parameter and
; Y is the dependent parameter to be plotted.
; y: in, optional, type=any
; A vector representing the dependent values to be plotted.
;
; :Keywords:
; addcmd: in, optional, type=boolean, default=0
; Set this keyword to add the command to the resizeable graphics window cgWindow.
; charsize: in, optional, type=float, default=cgDefCharSize()
; The character size for axes annotations. Uses cgDefCharSize to select default
; character size, unless !P.Charsize is set, in which case !P.Charsize is always used.
; color: in, optional, type=string/integer, default='black'
; If this keyword is a string, the name of the data color. By default, 'black'.
; Color names are those used with cgColor. Otherwise, the keyword is assumed
; to be a color index into the current color table.
; psym: in, optional, type=integer
; Any normal IDL PSYM values, plus any value supported by the Coyote Library
; routine cgSYMCAT. An integer between 0 and 46.
; symcolor: in, optional, type=string/integer, default='black'
; If this keyword is a string, the name of the symbol color. By default, 'black'.
; Otherwise, the keyword is assumed to be a color index into the current color table.
; symsize: in, optional, type=float, default=1.0
; The symbol size.
; _ref_extra: in, optional, type=any
; Any keyword appropriate for the IDL OPlot command is allowed in the program.
;
; :Examples:
; Use as you would use the IDL OPLOT command::
; cgPlot, cgDemoData(17), Color='olive'
; cgPlot, cgDemoData(17), Color='blue', SymColor='red', PSym=-16, /Overplot
