  Display the following animation graph on the tkinter,environment:python3.6 +windows10 desktop
  Below is  mpf_animation_demo1.py:
  ```python
  import pandas as pd
  import mplfinance as mpf
  import matplotlib.animation as animation
  
  idf = pd.read_csv('data/SPY_20110701_20120630_Bollinger.csv',index_col=0,parse_dates=True)
  idf.shape
  idf.head(3)
  idf.tail(3)
  df = idf.loc['2011-07-01':'2011-12-30',:]
  
  fig = mpf.figure(style='charles',figsize=(7,8))
  ax1 = fig.add_subplot(2,1,1)
  ax2 = fig.add_subplot(3,1,3)
  
  def animate(ival):
      if (20+ival) > len(df):
          print('no more data to plot')
          ani.event_source.interval *= 3
          if ani.event_source.interval > 12000:
              exit()
          return
      data = df.iloc[0:(20+ival)]
      ax1.clear()
      ax2.clear()
      mpf.plot(data,ax=ax1,volume=ax2,type='candle')
  
  ani = animation.FuncAnimation(fig, animate, interval=250)
  
  mpf.show()
