# coyote: CGOPLOT

- coyote/Graphics
- [Source code]

Description

      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.

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
