Sneaky way that improperly “scaling”
charts can give you the perception of what possible outcome has for the
near future. It creates an air of
uncertainty and fear. www.thereformedbroker.com/2013/05/03/lying-with-charts/
IMO scale manipulation is not necessarily a question of false or improper but one of appropriate or proportional. There are no hard and fast rules. The basic question is, do the chart designer's choices result in a fair presentation of the data? And then you're down to what is fair.
