With configurations - Live Example

<ReactSpeedometer
  maxValue={500}
  value={473}
  needleColor="red"
  startColor="green"
  segments={10}
  endColor="blue"
/>

Custom Segment Colors - Live Example

<ReactSpeedometer
  value={333}
  segments={5}
  segmentColors={[
    "#bf616a",
    "#d08770",
    "#ebcb8b",
    "#a3be8c",
    "#b48ead",
  ]}
  // startColor will be ignored
  // endColor will be ignored
/>

Custom Segment Labels - Live Example

  // 'customSegmentLabels' prop takes an array of 'CustomSegmentLabel' Object
  /*
  type CustomSegmentLabel = {
    text?: string
    position?: OUTSIDE/INSIDE
    fontSize?: string
    color?: string
  }
  */

  <ReactSpeedometer
    value={777}
    currentValueText="Happiness Level"
    customSegmentLabels={[
      {
        text: "Very Bad",
        position: "INSIDE",
        color: "#555",
      },
      {
        text: "Bad",
        position: "INSIDE",
        color: "#555",
      },
      {
        text: "Ok",
        position: "INSIDE",
        color: "#555",
        fontSize: "19px",
      },
      {
        text: "Good",
        position: "INSIDE",
        color: "#555",
      },
      {
        text: "Very Good",
        position: "INSIDE",
        color: "#555",
      },
    ]}
  />

Custom Segment Stops - Live Example

  <ReactSpeedometer
    customSegmentStops={[0, 500, 750, 900, 1000]}
    segmentColors={["firebrick", "tomato", "gold", "limegreen"]}
    value={333}
  />
  // `segments` prop will be ignored since it will be calculated from `customSegmentStops`
  // In this case there will be `4` segments (0-500, 500-750, 750-900, 900-1000)
/>

Fluid Width Example - Live Example

// Speedometer will take the width of the parent div (500)
// any width passed will be ignored
<div style={{
  width: "500px",
  height: "300px",
  background: "#EFEFEF"
}}>
  <ReactSpeedometer
    fluidWidth={true}
    minValue={100}
    maxValue={500}
    value={473}
    needleColor="steelblue"
  />
</div>

Needle Transition Example - Live Example

<ReactSpeedometer
  value={333}
  needleColor="steelblue"
  needleTransitionDuration={4000}
  needleTransition="easeElastic"
/>

Force Render component on props change - Live Example

// By default, when props change, only the value prop is updated and animated. 
// This is to maintain smooth visualization and to ignore breaking appearance changes like segments, colors etc. 
// You can override this behaviour by giving forceRender: true

// render a component initially
<ReactSpeedometer
  width={200}
  height={200}
/>
// Now, if given forceRender: true, and change the appearance all together, the component will rerender completely on props change
<ReactSpeedometer
  forceRender={true}
  segments={15}
  width={500}
  height={500}
/>

Needle Height Configuration Example - Live Example

<ReactSpeedometer
  value={333}
  needleHeightRatio={0.7}
/>

You can give a value between 0 and 1 to control the needle height.

Gradient Like Effect - Live Example

<ReactSpeedometer
  value={333}
  maxSegmentLabels={5}
  segments={1000}
/>

Credits:

react-d3-speedometer was started as a react port of the following d3 snippet - http://bl.ocks.org/msqr/3202712. Component template was initially bootstrapped with React CDK. Also, many thanks to react and d3 ecosystem contributors.

Contributing:

PRs are welcome. Please create a issue/bugfix/feature branch and create an issue with your branch details. Probably I will create a similar branch in the upstream repo so that PRs can be raised against that branch instead of master. master-v0.x is the main branch for React 16 compatible changes.

Notes

• 1.x versions are compatible with React & React DOM Versions v17.x
• 0.x versions are compatible with React & React DOM Versions v16.x For every subsequent major react upgrade, react-d3-speedometer will be bumped to next major versions. For example 1.x will be compatible with React 17.x so on and so forth ...
