Just in case try the latest release:

Strange, I am able to plot this file with no problems, without setting
"transf". Here is what I did:

  from grads import gacm
  ga.open('testfile.nc')
  ga.imshow('1e6*sconc_dust',cmap=gacm.jet_l)

The image is attached. For the record, I am running python 2.7 from EPD
7.1-2 on Mac OS X.
