@x011 Change the line containing if oldSeries: in C:\Python38\lib\site-packages\tacharts-0.0.30-py3.8.egg\TAcharts\wrappers.py to if oldSeries.any():.

@x011 Change the line containing if oldSeries: in C:\Python38\lib\site-packages\tacharts-0.0.30-py3.8.egg\TAcharts\wrappers.py to if oldSeries.any():.

I did make that change as mentioned but now i am getting: AttributeError: 'NoneType' object has no attribute 'any'
Please advise
