Both Threads Doesn't Work simultaneously Python3 , Raspberry PI

0

Here's My code I want to start both Thread together But it isn't starting.First Thread helps me in posting my data taken from sensor to ".csv" file and the second thread takes data from that file and plots a graph by using matplotlib.SO they should run simultaneously to give a proper live graph output. Please Help.

My Code:

import Adafruit_DHT

import time

import csv

import sys

import matplotlib.pyplot as plt

import matplotlib.dates as mdates

import matplotlib.animation as animation

from datetime import datetime

from threading import Thread 



csvfile ="temp.csv"



fig = plt.figure()

rect = fig.patch

rect.set_facecolor('#0079E7')

count = "0"



class Graph:



    def __init__(self):

        self.count = ""



    def storeD(self):

        while True:
