After successfully saved a png picture, you can not use it

[wangzili]

for example:

def create_pie():
        figure(1,figsize=(6,6),facecolor=(0,0,0))   
        ax = axes([0.1, 0.1, 0.8, 0.8])
        fracs = self.data 
        labels = '1','2','3','4','5','6'

        explode=(0,0,0,0,0,0)    
        patches, texts = pie(fracs, explode=explode, labels=labels, shadow=True) 
        savefig('pie.png',facecolor=(0,0,0))

If you call create_pie() in other places, it will show Resource "pie.png" was not found on the path

create_pie()
pyglet.resource.image('pie.png')

This sounds more like this is a pyglet issue than an mpl issue. If you open the png some other route does it look correct?

What do you think the bug in matplotlib is?

I 'm very sorry for my fault, it is pyglet a issue ,sorry!!!

I have a new problem.When the operation is repeated for a picture, the picture will continue to change, but the last time label not disappear,can you tell me the reason？
paste my code:
#encoding:utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

import time
import json
import urllib2
from random import randint as ra
from pylab import *

class Pie(object):
def init(self, data, date_time=None):
self.data = data
self.date_time = date_time
self.create_pie()

def create_pie(self):
    figure(1,figsize=(6,6),facecolor=(0,0,0))  
    ax = axes([0.1, 0.1, 0.8, 0.8])
    fracs = self.data
    labels = 'hello','world','you','are','lucky','boy'

    explode=(0,0,0,0,0,0)   
    #patches, texts, autotexts = pie(fracs, explode=explode, labels=labels, autopct='%1.1f%%', shadow=True)  
    patches, texts = pie(fracs, explode=explode, labels=labels, shadow=True)        
    for i in texts:
        i.set_color('w')
    title('Raining Hogs and Dogs'.encode('utf-8'), bbox={'facecolor':'0.8', 'pad':5})
    savefig('pie.png',facecolor=(0,0,0))

def make_png(date_time=None):
m = ra(10, 50)
n = 60-m
data = ['10', '10', '10', '10', m, n]
print data
Pie(data)

if name == "main":
while 1:
make_png()
time.sleep(1)

Your axes() constructor is simply overlaying a new axes on top of any
existing axes from previous runs. If you use subplots(111), then it should
only create it once. Subsequent calls will fetch the already created axes.

You will also see previous plots as well. You may want to call
"hold(False)" as well.
