Use Line Charts for Trends
Line charts are ideal when the question is about direction over time, such as traffic growth, monthly revenue, temperature change, or progress across weeks.
Choose Straight, Smooth, or Stepped
Straight lines work well for most continuous data, smooth lines create a softer presentation, and stepped lines are better for discrete jumps like pricing tiers or thresholds.
Multiple Series Add Context
Comparing two or more lines in the same chart can reveal whether values move together, diverge, or cross over at key points.
Use Area Fill Carefully
Area fill can help emphasize magnitude, but it works best when the chart is simple and not overloaded with too many overlapping series.
