How to Read a Dive Deeper Trend Chart
When a story involves real numbers tracked over time or compared across categories, Dive Deeper generates a chart directly from the reported figures.
By Headlinne Editorial Team · Updated on
Two chart types, chosen automatically
A line chart is used when a number changes over time — a price, a count, a percentage tracked across dates. A bar chart is used instead when the comparison is across categories rather than time, like different regions or groups.
Every point is a real reported figure
Nothing on the chart is estimated or interpolated — each plotted point corresponds to a specific number that actually appeared in a cited source, matching the figures in the statistics section of the report.
Simple by design
The chart favors clarity over density — clean axes, a legend when more than one series is shown, and enough labeling to understand the numbers at a glance without needing to zoom or interact.
Absent without real numbers
If a story does not include at least a couple of genuinely comparable reported figures, no chart is generated — a single isolated statistic is shown as text instead, not forced into a chart with only one data point.
Where the data comes from
Every point on the chart is a figure a cited source actually reported. Headlinne does not interpolate between gaps or estimate to smooth a line, which means a chart occasionally looks sparser than it might elsewhere — and also that you can open the source behind any point and check what it measured.
Key takeaways
- ✓Every trend chart Headlinne draws is built from figures reported in cited sources, so the underlying numbers stay checkable.
- ✓Line charts show a number over time; bar charts show a comparison across categories.
- ✓Every plotted point is a real figure from a cited source, matching the statistics section.
- ✓A chart only appears when there are enough genuinely comparable reported numbers.
Frequently asked questions
Where do the numbers in a trend chart come from?
From statistics the research pass actually retrieved and cited. Headlinne does not interpolate or estimate to make a line look smoother — where the data is not there, the chart is not drawn.
Does Dive Deeper ever combine numbers from different sources into one chart?
Yes, when they measure the same thing — for example tracking one figure across several reports over time — but each point still traces back to the specific source that reported it.
