All examples in 1, 2 or 3 can be used when appropriate. A good example is sometimes 150k vs 155k is a massive difference and matters a lot. Sometimes it doesnt. It all comes down to what you are trying to present and if it is helping to inform or misinform.

Just make sure axis are clearly labeled with values and units. Use your best judgement on how to present data. As a viewer just make sure you observe the axis and the details. Dont just glance at a chart, glancing is useless and you will get bamboozled sooner or later . . . Almost certainly sooner.

Agreed. There are lots of examples where you really shouldn't start the Y axis at zero, e.g. if zero is not a reasonable value of whatever measure you're displaying. If I want to display the past few years' average temperatures in Miami, I should not start either the X-axis (year) or the Y-axis (temperature) at zero.

1 is perfectly OK for when you need to zoom in to see the difference. Perhaps it can be better notified that the axis doesn't start at zero

2 is perfectly OK when you want to show correlation between to series that don't necessarily have the same unit or magnitude.

3 is the most questionable one because three years is a very short time frame (for some things). You can address that by adding a previous trend line.
I don't know if it qualifies as cherry picking though, or at least it's not what people mean when they use that term.

All in all these are not deceptive if you know how to look at a chart and if there's a modicum of context to the chart.

I appreciate the effort but not necessarily the execution.

Alibaba sells garbage products for cheap prices and uses every last bit of information about you to spam your phone and email. I’m still getting spam calls in Chinese 5 years after trying out their service. Never bought a thing from them.
