Feature: Per-panel time range / timescale options on dashboards

[SemoTech]

Context

SemoTech — self-hosted LogTide v1.3.1, custom dashboard Caddy WAN Geography (geo map, Top-N tables, log table, time series).

Thanks again for the 1.3.x dashboard panel work — we’re live on it. Related: viewport jump filed separately as #304.

Problem

Panel lookback is fixed to a small enum and differs by panel type. There is no global dashboard time picker, and several widgets we use for WAN traffic can’t express common windows like 48h or an arbitrary last N days.

Today (from shared types in 1.3.1):

Panel	Field	Allowed values
top_n_table	interval	1h | 24h | 7d
geo_map	interval	1h | 24h | 7d
time_series	interval	1h | 6h | 24h | 7d | 30d
log_table	timeRange	15m | 1h | 6h | 24h | 7d

For ops review we often want last 48 hours (or 3d / 14d) on Top Locations / Geo map / Top Blocked without jumping straight to 7d.

Request

1. Per-panel timescale control in each widget’s config (already partially there — extend it).
2. Ideally also a dashboard-level time range that panels can inherit (with per-panel override), similar to Grafana.
3. Broader preset set, e.g. 1h / 6h / 12h / 24h / 48h / 7d / 30d, and/or a custom relative window.
4. Align naming (interval vs timeRange) across panel types if practical.

Acceptance ideas

• top_n_table and geo_map support at least 48h (or custom relative range)
• Editing a panel’s time scope is obvious in the UI (not only YAML/API)
• Optional: dashboard default time range with panel override

Happy to test from our Caddy WAN dashboard once this lands.

Thanks, all of this is reasonable. Plan: broaden and align the per-panel presets first (48h included), then look at a dashboard-level default range with per-panel override as part of the same work. Will update here once it's on develop, happy to have you validate it on your WAN dashboard.

This landed on develop (PR #306). All window-scoped panels now share one preset list (15m, 1h, 6h, 12h, 24h, 48h, 3d, 7d, 14d, 30d) with readable labels, and there is a dashboard-level time range picker in the toolbar that temporarily overrides every panel (view-only, per-panel configs stay untouched). Two silent bugs fixed along the way: the time_series panel always rendered the last 24h whatever its interval said, and the top services table always aggregated 7 days. Last seen now also works on the service dimension. Ships with the next release; happy to have you test it from develop.

Thanks @Polliog — this is exactly what we needed for WAN ops review.

We’ll test on the next release against our Caddy WAN Geography dashboard: the expanded preset list (especially 48h), the dashboard-level time range picker with per-panel configs unchanged, and the time_series / top services interval fixes you mentioned in PR #306.

We’re on stable latest today and will upgrade when the release drops rather than tracking develop. Happy to confirm here once we’ve exercised it in production.
