C Description: This program shows how to create an XyPlot object
C with some of the XyPlot line resources tweaked. A
C resource file is used to changed the resources.
C This program uses the same Y-axis dataset as the
C example "xy02", but this time values for the X
C axis are specified, changing the look of the plot.
C
C The "CoordArrays" object is used to set up the data.
