42	Plotting user polylines in different colors	arango	Arango	"Added the capability to plot user polylines in different colors.  The the user polylines are overlayed if '''IREF=-2''' in the input script. The user lines locations are read from FORTRAN unit 35 ('''fort.35''') containing the (lat,lon) pairs.  Each line is separated by a '''999.0''' special value (drawing pen up).  The user can specify the color (iR,iG,iB) for each polyline segment.  An simple example of the file '''fort.35''' containing the (lat,lon) pairs is:


{{{
 999.000000                  0  255    0
   8.800000   118.000000
   8.800000   128.000000
 999.000000                237  107  172
  11.300000   119.650000
  11.300000   122.010000
 999.000000                153    0  204
  12.200000   120.250000
  12.200000   121.050000
 999.000000                255  255    0
   6.000000   121.300000
  12.250000   121.300000
 999.000000                255  255  255
   8.550000   123.100000
   9.030000   123.100000
 999.000000                255    0    0
   9.000000   125.320000
  10.500000   125.320000
 999.000000   999.000000
}}}

Notice that the user has the choice to specify the color after the first special value '''lat=999.0'''.  That is, '''iR=lon=???'''. If lon=999.0, then the polyline color is that specified in the color palette file.

The above file was in the following plot:
