Listen to the pattern

A time-series is a pattern. It climbs upward and descends, patterns are stable or swinging, they change slowly or abruptly. The pattern is more important than the actual values. To understand the pattern it helps to read it aloud to yourself. “The first value is the smallest. A steep ascent follows. Then a descent roughly to the bottom again.” Time-series patterns are similar to sound patterns. A sound pattern climbs or descends just like values do. You can hear what you see and see what you hear. If you simultaneously hear and see the same your understanding is faster. Sounds read the pattern to you. Test audio sparklines.
