Historical

Historical shows observations charts across day, month, and year periods.

  • Change card order and visibility in Settings > Historical.
  • For chart-by-chart behavior, see Historical Charts.

Time range

Use the toolbar period picker to switch between day-level detail, month summaries, and year summaries:

  • Choose Today, Yesterday, One week ago, One month ago, or One year ago for observation-level detail on a specific day.
  • Choose This month or Previous month for daily summaries across a month.
  • Choose This year or Last year for broader yearly patterns and summaries.

Hover or drag across a chart to inspect values. Use the calendar menu or the previous and next arrows to move between available periods.
