Graphics

cgOPlot, x [, y] [, /ADDCMD] [, CHARSIZE=float] [, COLOR=string/integer] [, PSYM=integer] [, SYMCOLOR=string/integer] [, SYMSIZE=float] [, _REF_EXTRA=any]

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 to be installed on your machine.

Parameters

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
