ACT Preparation / Unit 19 ACT 1806 short lesson, about 20 seconds
Graphs With More Than One Series
Captions available
The idea
A graph can show several data series at once, each marked by its own line style, symbol or color, explained in a legend.
In practice
Two invented lines show plant height over time, one for full sun and one for shade.
Where people slip
Match each line to the legend before reading; swapping the series reverses the conclusion.
