DataLogger help needed

I have been working to setup DataLogger on a Raspberry Pi 3. It will run and fetch one line of data and put into the database but fails when try to plot:

@raspberrypi:~/SDL_Pi_DataLogger $ python DataLogger.py

SDL_Pi_Datalogger

Will work with the INA3221 SwitchDoc Labs Breakout Board
Will work with the ADS1115 SwitchDoc Labs Breakout Board
Will work with OurWeather - Complete Weather Kit
Will work with SwitchDoc Labs WxLink Wireless LInk
