Re: [Gnuplot-py-users] maximum number of ydata

[Pablo A. <pa...@gm...>]

Hi,

I've tried to replot more than 25 times using gnuplot directly and I
can, so the problem must be in my code or in gnuplot.py. The error
message I receive is this:

Traceback (most recent call last):
  File "bands-spin.py", line 153, in ?
    g.replot(bandplot[iplot])
  File "/usr/lib/python2.4/site-packages/Gnuplot/_Gnuplot.py", line
322, in replot
    self.refresh()
  File "/usr/lib/python2.4/site-packages/Gnuplot/_Gnuplot.py", line
214, in refresh
    plotcmds.append(item.command())
  File "/usr/lib/python2.4/site-packages/Gnuplot/PlotItems.py", line
192, in command
    return string.join([
  File "/usr/lib/python2.4/site-packages/Gnuplot/PlotItems.py", line
451, in get_base_command_string
    fifo = _FIFOWriter(self.content, self.mode)
  File "/usr/lib/python2.4/site-packages/Gnuplot/PlotItems.py", line
411, in __init__
    self.start()
  File "/usr/lib/python2.4/threading.py", line 416, in start
    _start_new_thread(self.__bootstrap, ())
thread.error: can't start new thread


where bands-spin.py is my code. The problem appears in a loop like this:

for iplot in range(0,norb):
  g.replot(bandplot[iplot])

It works fine if I set norb=24, if I set it to 25 sometimes work and
sometimes it doesn't (the data plotted doesn't change!!) and if I set
it to 26 or more it always crash.

Thank you for your help

Pablo
