AttributeError: 'XXX' object has no attribute '_QwtPlot__data' #77

Closed PierreRaybaut closed 11 months ago

This error occurs whenever a QwtPlot object is being destroyed unexpectedly.

So, the solution would be to handle this error:

Silently, if we identify that this can occur when exiting Python properly
By raising an explicit exception or RuntimeWarning if we confirm that it should not happen
