Title:
  Repeated plot.plot() fail

Status in Yade:
  New

Bug description:
  Hi there,

  Since bugs report get a lot of attention these days :-) let me add
  another one:

  #######################
  from yade import plot
  plot.addData(x = 1 , y = 5)
  plot.plots = {'x':'y'}

  plot.plot()
  plot.plot()
  #######################

  gives error messages (pointing to py/plot.py, see [*]  below) at the
  second plot.plot() command.

  It seems you can also replace any of the 2 plot.plot() (or both) with
  eg plot.plot(noShow=True).savefig('test.png') and get the same
  behavior.

  I would prefer having the possibility to ask twice for a plot in one
  YADE session, what do you think ?
