Threshold sweep
Alerts per week at every threshold.
Definition · Updated Nov 2, 2026
A threshold sweep draws how many alerts a rule would fire at each threshold, with the current and proposed settings marked. You pick the threshold by its cost in alerts. Use it for alert tuning and SLO targets.
Pay once. Every update included.

Threshold across (93% to 97%) and alerts per week up (0 to 20).
One data object in the sample’s shape: alerts per threshold. The docs page lists every field and links its JSON Schema; the sample data comes with the component, so you can start from it and swap in your own.
Series take the preset’s data colours in order, and states such as up, down or warning take its status colours. Change the preset in Figma or in code to recolour every chart at once.
XS, S, M and L, in light and dark. Each size is laid out again from the data, so text and lines keep their size.
Yes. It plays in when it scrolls into view, and when the data changes every mark moves from its old place to its new one. With reduced motion on, it does not move.
Yes. The Figma component comes with Figma and Complete, the React component with Code and Complete.
Ask for it by name. The MCP server tells the agent what data it needs and runs the same command: npx shadcn add @chartory/threshold-sweep. You review the diff.
