Matplot figure not rendered getting "Not Responding" message

Question

I am trying to update candlestick chart every 1min. I am using mplfinance to create candlestick plots and yahoo finance to get the data.

I am using time.sleep to pause and refresh.

Issue is plot window shows "Not Responding". Screenshot attached below. Where am I going wrong ? Requesting guidance.

Below is the complete code.

#Importing packages


import yfinance as yf

# Calling Pandas to create dataframe
import pandas as pd

#Importing Datetime package

LiveData['Datetime'] = pd.to_datetime(LiveData['Datetime'])
LiveData=LiveData.set_index('Datetime')

fig = mpf.figure(style='charles',figsize=(12,7))
    
ax1 = fig.add_subplot()
ax1.xaxis.set_major_locator(plt.MultipleLocator(1))
ax1.xaxis.set_major_locator(plt.MaxNLocator(20))
    
mpf.plot(LiveData,ax=ax1, type='candle',show_nontrading=True,volume=False)

    nyc_time, alarm, opentime = get_time()
    if nyc_time > alarm or nyc_time < opentime:
        if nyc_time > alarm:
            print("NASDAQ Closed for the day")
            break

            print("NASDAQ has not opened for the day")

    Get_Data(LiveData)   
    

Appreciating your time and guidance
