Inline Labels Line

A multi-series line chart that labels each series directly at its endpoint — showing name, latest value, and period-over-period delta. Eliminates the need for a separate legend and makes trends instantly readable.

Examples

When to Use

  • Comparing multiple KPI trends over time (revenue by region, team velocity)
  • Executive dashboards where readers need name + value + change at a glance
  • Replacing a standard line chart when the legend is hard to cross-reference
  • Time-series forecasting with the Date Logic feature to dim past / dot future

Tips & Best Practices

  • Inline labels replace the need for a traditional legend — each series is labeled at its endpoint with name, value, and delta
  • Enable Date Logic to automatically dim past data and dot future projections
  • Use the "last2" marker mode to highlight the latest two data points for quick trend reading
