Dashboards overview

Every dashboard in Chomper is a grid of panels you arrange yourself — there's no fixed layout to work around. This page covers how dashboards are organized, what a panel can be, and how the shared time range picker drives every panel on the page at once.

The dashboard catalog

The catalog lists every dashboard you have access to, newest first, with its panel count, current version, and when it was last updated. Creating one takes a title and an optional description — it starts empty, ready for panels. Deleting a dashboard asks for confirmation twice before it goes through, so it isn't one accidental click away.

Panel types

Every panel is driven by a ClickHouse query you write yourself — there's no separate category of fixed, non-SQL panels to reach for first. Five panel types are available: Time series, Pie, Gauge, Geo heatmap, and Table, each turning its query's result into a specific kind of chart.

Each panel type has its own guide with worked examples — see Panel types.

Editing a dashboard

Clicking Edit turns the grid interactive: drag a panel to move it, drag its corner to resize it, and use Add panel to drop in a new one. Nothing is written until you click Save — every layout change, added panel, or edited query is staged locally first, so Cancel always gets you back to exactly where you started.

Any panel can carry a short note — see Panel types for how the note editor and its sticky-note indicator work.

The time range picker

A single time range picker, top-right, drives every time-bound panel on the dashboard at once. Three ways to set it:

• Quick presets — from “Last 1 hour” through “Last 30 days”.
• Custom range — relative expressions like now-6h or now-7d, or an absolute date and time.
• Calendar — pick a start day and an end day directly.

None of these take effect until you click Apply time range — so browsing presets never jumps the dashboard around under you. A dashboard can also be given its own default range, so it always opens the way you left it rather than the standard last-24-hours view.

Note. A relative range (anything containing now) keeps sliding forward automatically as time passes; an absolute range stays fixed to the exact window you picked.
