Add the chart
One command adds the Overlapping areas component to your project.
npx shadcn add @chartory/overlapping-areas - 3
Use it
Pass your rows. The props are the Figma properties.
usage.tsximport { OverlappingAreas } from "@/components/chartory/overlapping-areas"<OverlappingAreas data={venueVolume} size="m" legend/>
Props
<OverlappingAreas>
Every prop but data is a Figma property with the same name and values.
OverlappingAreasData
The data prop: one object for the whole chart.
OverlappingAreasSeries
One object per entry in series.
The data as a JSON Schema: schemas/overlapping-areas.json
Overlapping areas chart: a React and Figma chart in four sizes
What does an overlapping areas chart show?
An overlapping areas chart draws two or three filled series on one axis with see-through fills, so you can compare their levels without stacking them. Where one rises above another, you see it. Use it for venues, channels or regions that run side by side.
Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.
What is the Overlapping areas component?
It is one <OverlappingAreas> component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is two or three series, one value per point.
Sizes XS, S, M and L re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.
When should I use it?
- Are there three series or fewer? Yes means the overlapping areas fit.
- Is each series its own level? Yes means the overlapping areas fit.
- Do the levels matter, not only the trend? Yes means the overlapping areas fit.
When does another type fit better?
- More fills turn to mud. Use Multi-line chart instead.
- The series add up to a total. Use Streamgraph instead.
- Only direction and crossings matter. Use Multi-line chart instead.
Overlapping areas questions
Installing, data, Figma and plans.
Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.
It is free in Hearth and MIT licensed: add the @chartory registry URL once, no token, then run npx shadcn add @chartory/overlapping-areas. The Installation guide has the steps.
Yes. Connect the Chartory MCP server and ask for the overlapping areas chart; the agent runs the same command and you review the diff.
Two or three series, one value per point. The sample data comes with the component, and the props table lists every field.
XS, S, M and L, in Figma and in code. Each size is laid out again from the data, so text and lines keep their size.
Yes. chart/013-overlapping-areas has the same properties as the component.
Yes. Every paint is a token, so the chart follows light and dark mode and the collection you pick.
None for Hearth: it is free in the public registry, no token. The Signal collection (@chartory/signal) comes with Code and Complete.
