To plot isotacs, you would specify SNPARM=sped or SNPARM=sknt (for metes per second or knots respectively). Set CINT= (blank) or CINT=0 for the program to chose a default interval. Set CTYPE=c for contour lines. For the Yaxis, the ystrt (minimum level) would be 100 and the Ystop (maximum level) would be 10 for 100mb to 10mb (where VCOORD=pres). You may be flopping min and max (recall pressure decreases upward). Steve Chiswell
