Find the main patterns before choosing figures. For a changing series, the start, finish and a major turning point may explain more than a list of every value.

If a line rises overall but has one large fall halfway through, the start and finish alone would hide that fall, right?

Right. That fall is a reason to include an intermediate value. Choose numbers because they support an important feature, not because they're evenly spaced across the chart.
