Linear Gauge

A Linear Gauge in REAVIZ uses a linear scale to display a specific data point using a dial over a linear scale with defined limits. This type of gauge is ideal for showing how a value fits within a range.

Types supported by reaviz:

Where to use:

Display Single Values: Ideal for showing specific data points within a range.
Track Metrics: Useful for tracking metrics such as risk scores or performance indicators.
Compare Multiple Values: Great for comparing multiple values in a clear, linear format.

Quick Start

To create a Linear Gauge, use import the LinearGauge and give it data. The chart will automatically configure itself with the default options exposed via props.

import { LinearGauge } from 'reaviz';


export default function App() {
  return (
    <LinearGauge
      width={300}
      height={100}
      data={{ key: 'Risk Score', data: 74 }}
    />
  );
}

import { LinearGauge } from 'reaviz';

export default function App() {
  return (
    <LinearGauge
      width={300}
      height={100}
      data={{ key: 'Risk Score', data: 74 }}
    />
  );
}

In this example, we only pass one data object, however, we can pass multiples and it will distribute the values across them.

Examples

Single-series gauges

Multi-series gauges
