react-gauge-component

React Gauge Chart Component for data visualization.

This is forked from @Martin36/react-gauge-chart 0b24a45. Key differences:

• Added min/max values
• Added grafana based gauge
• Added arcs limits in value instead of percent
• Added inner/outer ticks to the gauge for reference of the values
• Added blob pointer type
• Added arrow pointer type
• Added tooltips on hover for the arcs
• Added arc with linear gradient colors
• Full responsive
• All render flow fixed and optimized avoiding unecessary resource usage. Performance test, left is original: https://user-images.githubusercontent.com/45375617/239447916-217630e7-8e34-4a3e-a59f-7301471b9855.png
• Refactored project structure to separated files
• Refactored to Typescript
• Added complex objects for better modulation and organization of the project
• Fixed Rerenderings making arcs to be repeated in different sizes
• Fixed needing to set height bug
• Fixed needing to set id bug

Usage

Install it by running npm install react-gauge-component --save or yarn add react-gauge-component. Then to use it:

import GaugeComponent from 'react-gauge-component'

//Component with default values
<GaugeComponent />

For next.js you'll have to do dynamic import:

import dynamic from "next/dynamic";
const GaugeComponent = dynamic(() => import('react-gauge-component'), { ssr: false });

//Component with default values
<GaugeComponent />

• maxValue: number: The maximum value of the gauge. Default: 100.
• arc: object: The arc of the gauge.
  • cornerRadius: number: The corner radius of the arc. Default: 7.
  • padding: number: The padding between subArcs, in rad. Default: 0.05.

    • hideMinMax: boolean: Whether or not to hide the min and max labels. Default: false
    • ticks: Array<object>: The ticks of the gauge. When not provided, it will use default gauge ticks with five values.
      • value: number: The value of the tick.
      • valueConfig: object: The config of the tick's value label. When not provided, it will use default config.

Colors for the chart

The 'colorArray' prop could either be specified as an array of hex color values, such as ["#FF0000", "#00FF00", "#0000FF"] where each arc would a color in the array (colors are assigned from left to right). If that is the case, then the length of the array must match the number of levels in the arc. If the number of colors does not match the number of levels, then the first and the last color from the colors array will be selected and the arcs will get colors that are interpolated between those. The interpolation is done using d3.interpolateHsl.
