Chart Titles
A chart title should help readers understand what the visualization is saying, not merely identify it as a chart. Strong data-visualization systems separate the main message from supporting metadata.
Write a concise chart title that tells readers the main message or trend. Keep supporting measure, geography, and time-period detail in a subtitle or nearby metadata when your chart system supports it.
Key details
Important caveats
Metadata Boundary
Put supporting metadata such as measure, geography, and time period in a subtitle when the style system provides one, rather than overloading the title.
Further guidance
Message First
Use the chart title to communicate the main trend or takeaway when the chart has a clear finding, rather than naming only the chart type.
Style
Keep chart titles concise, front-loaded, active where appropriate, and in the capitalization style required by the publication; ONS uses sentence case.
