;; Description: This program shows how to create an XyPlot object
;; and how to tweak some of the XyPlot resources to
;; change the appearance of the plot. A resource file
;; is used to change the resources except in those
;; cases where a resource is an array and can only be
;; changed programmatically.
;;
;; The "CoordArrays" object is used to set up the data.
;;
;
; Begin NCL script.
