  • Create color contour plots of "generic" 2D arrays from 2D or larger multidimensional variables.
  • Create line plots of data from 1D or larger multidimensional variables.
  • Combine two geo-referenced arrays in one plot by differencing, summing or averaging.
  • Create map plots of trajectory data based on the CF convention or similar.
  • Plot lon-lat data on a global or regional map using any of over 200 map projections or make a zonal average line plot.
