Place core data restatements directly on the chart

Put text that restates the plotted result directly on the chart instead of leaving it only in surrounding copy. For example, add on-chart annotations that label the two colored areas and state the core contrast, so the annotation also acts as a direct color key.

When the main message is already in the plotted values, readers do not need a separate layer of prose to discover it. Keeping the restatement on the chart lets the marks and the explanation be read together.

Mechanism: On-chart annotations shorten the distance between the plotted pattern, the category meaning of the colors, and the headline takeaway.

Evidence: The post distinguishes between restatements of the core data and added information, and recommends placing restatements closer to the chart itself as annotations, including text that directly explains what the chart’s two areas represent and emphasizes their difference (Mintzer-Sweeney, 2024).

• User Goal: Show a stark, simple pattern so readers grasp it immediately.
• Data: The main message is a direct restatement of what is already plotted.
• Chart Setting: The chart uses colored areas or similarly distinct marks that still need a direct explanation.
• Audience: Readers are expected to get the main comparison from the chart itself.
• Success Criterion: Readers can tell what the marks represent and what the main contrast is without relying on nearby prose.

Break it when: The text adds information that is not itself the core plotted result. Why: That kind of information should sit farther away, such as in a subtitle or footnote, rather than compete with the chart annotation.

Sacrifice: The chart body has less room for other text. Risk: If added background stays in the same space, the core restatement loses prominence. Mitigation: Keep only the core restatement and the direct mark explanation on the chart.

Mistake: Leave the main summary in nearby prose while the plotted areas remain explained only indirectly. Why it fails: Readers must move back and forth between text and chart, and the marks still do not explain themselves.

Failure Sign: The chart cannot be understood without reading nearby copy first. Quick Check: Cover the surrounding prose. If the chart no longer tells you what the colored areas are or what the headline contrast is, the restatement is too far away. Stronger Test: Verify that the chart itself contains both the main comparison and the label-to-color mapping.

• Add a short annotation inside the chart that states the main difference shown by the data.
• Use that annotation text to label the plotted areas directly, so it doubles as a color key.
• Reduce or remove duplicated summary text that sits farther from the marks.
