    http://ngwww.ucar.edu/ngdoc/ng4.1/ref/hlu/obj/Transformation.res.html#trXMaxF
                                                                          trXMinF
                                                                          trYMaxF
                                                                          trMinF

      res = True
      res@trYMinF = -20.
      res@trYMaxF = 30.

    I would say the vast majority of graphics are generated via the
    gsn interfaces.

        Primarily, this is a step-by-step description of using the
        generic (gsn_code.ncl) plot interfaces. It has quite a bit
        of additional info also.

         Click on Graphics
         
         This has many examples of using the gsn_csm.ncl plot
         functions. I would say that most people use these
         because they often invoke common resources.
         
    good luck
