do you plot with ProbeLine then with that element activated, choose
Programmable Filter and put this script :

print "------------------"
pdi = self.GetInput()
nbp = pdi.GetNumberOfPoints()
vals = pdi.GetPointData().GetScalars("p")
for i in range(0,nbp):
  print "%d : %e" % (i,vals.GetValue(i))
print "------ done ----------"

of course you have to print in the csv format and to choose your variable
(instead of "p").
