Question

If the title of a chart does not convey enough information, the designer may need to
use longer, more detailed labels within the chart.
insert more information into a caption below the chart.
add a few lines of explanatory text between the title and the chart.
add a subtitle.

Answer 1

All of the above. Which option you pick depends on how much detail is needed and where it best belongs:

- Use longer, more detailed labels within the chart when the missing info is specific to axes, series, or data points.
- Insert more information into a caption when you need background, data source, methodology, or caveats that don’t belong in the chart itself.
- Add a few lines of explanatory text between the title and chart to summarize the key insight or highlight important context.
- Add a subtitle when you want a short, immediate extension of the title (e.g., timeframe, location, or metric).

Choose the least intrusive solution that conveys the necessary context without cluttering the visual.
