我有一个json文件数据（2Go），其中每一行是（threadTitle，numberOfSubscribers）
thread1 1092
thread2 44481
thread3 12105
thread4 2835
thread5 4292
...
我想用python绘制直方图：
Y：线程数
X：5个订阅者的范围。 [0到100]，[101到1000]，[1001到5000]，[5001到10000]和[10001和更多]
有没有办法有效地使用python中的任何库？
目前，我必须以这种方式预处理数据，然后绘制数据，但这看起来有点麻烦。
subreddit_subscriber = open("subreddit_subscriber.txt","w");
# 5 counters, one for each bin
subreddit_count = dict();
subreddit_count["below_100"] = 0;
subreddit_count["below_1000"] = 0;
subreddit_count["below_5000"]= 0;
subreddit_count["below_10000"] = 0;
subreddit_count["more_10000"] = 0;
with open(file, "r") as f:
for line in f:
subreddits = json.loads(line);
subscribers = subreddits["subscribers"]
#increment the counter according to the number of subscribers
if(subscribers <=100):
subreddit_count["below_100"] += 1;
elif (subscribers <= 1000):
subreddit_count["below_1000"] += 1;
elif (subscribers <= 5000):
subreddit_count["below_5000"] += 1;
elif (subscribers <= 10000):
subreddit_count["below_10000"] += 1;
else:
subreddit_count["more_10000"] += 1;
for key in subreddit_count.keys():
subreddit_subscriber.write(key + "\t" + str(subreddit_count[key]));
subreddit_subscriber.close();

**编辑：** After plotting Jezrael's code
答案 0 :(得分：0)
我认为您只能阅读要列出的值subscribers，然后创建Series并使用cut进行分级，value_counts进行计数，最后plot.bar：
L = []
with open(file, "r") as f:
for line in f:
L.append(json.loads(line)["subscribers"])
print (L)
s = pd.Series(L)
#print (s)
l = ['below_100','below_1000','below_5000','below_10000','more_10000']
a = pd.cut(s, bins=[-1,100,1000,5000,10000,np.inf], labels=l).value_counts()
#print (a)
a.plot.bar()
