Possible null reference return.

Converting null literal or possible null value to non-nullable type.

Possible null reference assignment.

Nullability of reference types in type of parameter 'sender' of 'void ExampleOnDemandPlotting.SimulateData_Tick(object sender, EventArgs e)' doesn't match the target delegate 'EventHandler' (possibly because of nullability attributes).

Non-nullable property 'AnalogyFactory' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Non-nullable event 'OnNewPointsData' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the event as nullable.

Non-nullable field 'simulateData' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable property 'Interactor' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.
