01 / Component Usage

Basic & Interactive Integration

Import BarBasic directly into your React client component. Provide an array of observations conforming to the data shape.

page.tsx

import { BarBasic } from "@/components/charts/recharts/bar-basic"

const data = [
  {
    "label": "Jan",
    "value": 186
  },
  {
    "label": "Feb",
    "value": 305
  },
  {
    "label": "Mar",
    "value": 237
  }
]

export default function ChartDemo() {
  return (
    <div className="w-full max-w-xl h-80">
      <BarBasic data={data} color="#10b981" />
    </div>
  )
}

Requires a client context ('use client') for DOM lifecycle and container measurement.

Expected ResultLive 220px

Container-aware width · 200px height

02 / Data Contract

Input Schema & Coordinates

Input data format for Basic Bar Chart. Records should provide required coordinates and metrics.

Chart data contract
Field	Type	Required	Meaning
`label`	`string`	Yes	Category label or horizontal axis timestamp
`value`	`number`	Yes	Metric numerical magnitude

Null / Missing Value Policy:

Missing values are gracefully handled or skipped depending on interpolation rules.

Coordinate Ordering Policy:

Records should follow monotonic sorting for sequential coordinate plots.

Example Observation Payload:

[
  {
    "label": "Jan",
    "value": 186
  },
  {
    "label": "Feb",
    "value": 305
  },
  {
    "label": "Mar",
    "value": 237
  }
]
