I updated to Org mode version 9.2.3 (release_9.2.3-390-gfb5091 @ /home/rmason/.emacs.d/org-git/lisp/)

This works but sets the results to verbatim, hence the exported &
compiled code does not include the graphic.

#+name: scaleplot03
#+begin_src python :results output graphics link :exports results :var data=test :var file="scaleplot03.pdf"
  import matplotlib.pyplot as plt
  import csv

  scale = []
  lescale = []
  cdscale = []

  energy = []
  leenergy = []
  cdenergy = []

  for row in data:
      scale.append(float(row[0]))
      energy.append(float(row[1]))
      if int(row[2]) != 0:
             lescale.append(float(row[0]))
             leenergy.append(float(row[1]))
      if int(row[3]) != 0:
             cdscale.append(float(row[0]))
             cdenergy.append(float(row[1]))        

  plt.plot(scale,energy, 'r+')
  plt.plot(lescale,leenergy, 'go')
  plt.plot(cdscale,cdenergy, 'bo')
  plt.xlabel('scale')
  plt.ylabel('energy (Ha)')
  plt.title('Energy vs scale')
  plt.legend()
  plt.savefig(file)
  print ("./%s" % file)
#+end_src

#+RESULTS: scaleplot03
: ./scaleplot03.pdf

This header does not work either:
#+name: scaleplot04
#+begin_src python :results file link :exports results :var data=test :var file="scaleplot04.pdf"
( same pythone code here)

#+RESULTS: scaleplot04
[[file:None]]
]]
#+end_src

Thank you for your help.

Roger
