Summary

  • Click any sparkline character in the detail view to inspect that data point
  • Shows approximate time ago, latency value, and UP/DOWN status
  • Esc dismisses tooltip without leaving detail view; click outside sparkline clears it
  • Uses existing BubbleZone zone manager — no new dependencies
  • 12 table-driven tests for index resolution (padding, truncation, edge cases)

Files

  • sparkline.go — resolveSparklineIndex() maps zone-relative X to data index
  • sparkline_test.go — table-driven tests for index resolution
  • tui.go — sparkTooltipIdx field on Model
  • update.go — handleSparklineClick() + Esc dismissal in detail view
  • view_dashboard.go — zones.Scan() enabled for detail view
  • view_detail.go — zone-marked sparklines + tooltip info line rendering

Test plan

  • go build ./... passes
  • go test ./... passes (all packages)
  • Manual: click sparkline chars, verify tooltip content
  • Manual: Esc dismisses tooltip, second Esc exits detail view
  • Manual: click on dot padding shows nothing

Click any sparkline character to see data point details — approximate
time, latency, and up/down status. Esc dismisses tooltip without
leaving detail view. Uses existing BubbleZone infrastructure with
zone-relative coordinate math for index resolution.
