[gradsusr] ploting problems

[Jennifer Adams]

Your defined variables U1 V1 U2 V2 U and V are all defined from longitude 0  to 360 -- this probably means you are writing out an extra column of data and so when you open eves_200-850.nc it does not pass the globe-wrapping test and therefore gives your negative longitudes as missing data. The fix is to use 'set x 1 <xsize>' before defining the variables in the first step.
