Dot plot with intervals
Estimates with how sure they are.
Definition · Updated Nov 2, 2026
A dot plot with intervals marks each estimate as a dot with a line for its confidence interval, against a target. Items whose interval crosses the target show as uncertain. Use it for on-time rates, conversion rates and survey results with sample sizes.
Pay once. Every update included.

Re-laid out, never scaled.
The same data at XS, S, M and L. Every size is redrawn from the data, so text and line weights never shrink.

When to use
How sure is each number?
Three signs it fits, and three signs another type fits better.
Is it estimates, not raw spread?
The spread of raw values.
Yes: Keep the dot plot with intervals
Code and Figma
One name in Figma and in code.
Every Figma property is a prop with the same name and values. One command installs it.

What people ask before they put a dot plot with intervals in a dashboard.
Something else?
hello@usechartory.comThe interval crosses the SLA line, so the data cannot yet say whether the carrier is above or below it. The legend names above SLA, uncertain and below SLA.
The estimate and its low and high per item, plus the target.
One data object in the sample’s shape: an estimate and an interval per item. 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 React component is free in the public registry in Hearth, no token needed; Signal comes with Code and Complete. The Figma component comes with Figma 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/dot-plot-with-intervals. You review the diff.
