Ubvuntu 20.04 python 3.8

With the May 29 2022 commit, I always get:

Traceback (most recent call last): File "/usr/local/lib/nanovnasaver/nanovna-saver.py", line 26, in from NanoVNASaver.main import main File "/usr/local/lib/nanovnasaver/NanoVNASaver/main.py", line 36, in from NanoVNASaver.NanoVNASaver import NanoVNASaver File "/usr/local/lib/nanovnasaver/NanoVNASaver/NanoVNASaver.py", line 28, in from .Windows import ( File "/usr/local/lib/nanovnasaver/NanoVNASaver/Windows/init.py", line 6, in from .DisplaySettings import DisplaySettingsWindow File "/usr/local/lib/nanovnasaver/NanoVNASaver/Windows/DisplaySettings.py", line 25, in from NanoVNASaver.Charts.Chart import ( File "/usr/local/lib/nanovnasaver/NanoVNASaver/Charts/init.py", line 2, in from .Frequency import FrequencyChart File "/usr/local/lib/nanovnasaver/NanoVNASaver/Charts/Frequency.py", line 37, in class FrequencyChart(Chart): File "/usr/local/lib/nanovnasaver/NanoVNASaver/Charts/Frequency.py", line 453, in FrequencyChart def _data_oob(self, data: list[Datapoint]) -> bool: TypeError: 'type' object is not subscriptable

I don't know if this is sufficient, but it seems to clear the error so far:
