Python-сообщество

Всем привет
Вообщем ситуация следующая, рисую я графики с помощью mathplot, много порядка 11 тысяч, это графики посещаемости минутные и часовые. Ругается mathplot сначало говорит

C:\Python27\lib\site-packages\matplotlib\pyplot.py:424: RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface (`matplotlib.pyplot.figure`) are retained until explicitly closed and may consume too much memory. (To control this warning, see the rcParam `figure.max_open_warning`).
max_open_warning, RuntimeWarning)

потом подвисает вылетает и пишет

Что посоветуете как быть??

вот код функции которая рисует

def paint_all(self, dir):       
        dir = dir
        self.count_cord()
        dir = os.path.join(dir)
        if not os.path.isdir(dir):
            os.makedirs(dir)
        #Paint Mins Graf
        t_min = self.all_min_count.keys()
        s_min = self.all_min_count.values()
        #grid(True)
        figure() 
        plot(t_min, s_min)
        savefig(os.path.join(dir, "all_mins.png"))
        #Paint Hours Graf
        t_hour = self.all_hour_count.keys()
        s_hour = self.all_hour_count.values()
        #grid(True)
        figure()
        plot(t_hour, s_hour)
        savefig(os.path.join(dir, "all_hours.png"))        
        #Paint Id mins
        for tid in self.tid_min_count.keys():
            t_min = self.tid_min_count[tid].keys()
            s_min = self.tid_min_count[tid].values()
            grid(True)
            figure()
            plot(t_min, s_min)
            savefig(os.path.join(dir, str(tid)+"_min.png"))
        #Paint id hours            
        for tid in self.tid_hour_count.keys():
            t_hour = self.tid_hour_count[tid].keys()
            s_hour = self.tid_hour_count[tid].values()
            grid(True)
            figure()
            plot(t_hour, s_hour)
            savefig(os.path.join(dir, str(tid)+"_hour.png"))

matplotlib освобождает память при вызове метода show(), но поскольку вам этого не нужно, решение тут: http://stackoverflow.com/questions/7101404/how-can-i-release-memory-after-creating-matplotlib-figures
