Time Range management (widget vs. dashboard)

[Viconours]

Describe your question

Hi!

I am building a dashboard to monitor a pilote phase for a RAG. But I'm confused on the time range management in widgets vs. dashboard.
I'd like to have on the same dashboard :

• A chart with the total number of unique users from the beginning of the experimentation.
• A chart with the unique active users over the last 7 days.
  It's possible to select a specific range when creating the widget but it's overriden by the time range selected for the whole dashboard so I cannot have two different time ranges on the dashboard.
  Am I misusing time range feature? Anyway to make this happen?

Thank you very much!
Victor

Based on the available documentation, the current dashboard implementation does not support having widgets with independent time ranges on the same dashboard. The dashboard-level time filter overrides individual widget time settings.

This is a limitation of the current architecture. When you configure time filters at the widget level during creation, these settings are indeed overridden by the dashboard's global time range selector(1).

Current Workaround Options:

1. Create separate dashboards for different time ranges (one for all-time metrics, another for 7-day metrics)
2. Manually adjust the dashboard time range when you need to view different time periods

Note on Unique User Count:

Be aware that there's a known issue with unique user ID counting in dashboard widgets where the system may show trace count instead of unique user count, even with correct filters applied(2). This may affect your "total number of unique users" metric.

The ability to have per-widget time ranges would require architectural changes to how dashboards handle time filtering. This functionality is not currently available in Langfuse dashboards(1)(3).
