Re: help: plot a variable from binary file

You could try modifying the line
tp&lon = lonGlobeFo(nlon,"lon","longitude","degrees_east")
to
tp&lon = lonGlobeFo(nlon,"lon","longitude","degrees_east") -180

It's true that this is not what the ydef specifies, but maybe the specification is wrong.
Also your fspan lines are not being used at all so you might as well get rid of them
