There is also another really nice version here

Install from NPM

npm install react-liquidchart

Example

For now, this will have to do.

Usage

import React, { Component } from 'react';
import { render } from 'react-dom';
import LiquidChart from 'react-liquidchart';

const stops = [
  <stop key={1} stopColor="someColor1" offset="5%" />
  <stop key={2} stopColor="someColor2" offset="50%" />,
  <stop key={3} stopColor="someColor3" offset="85%" />,
];

class ChartLiquid extends Component {
  constructor() {
    super();
  }

  render() {
    return (
      <div
        style={{
          width: '100%',
          height: '500px',
        }}
      >
        <LiquidChart
            responsive
            legend="Percentage of Completed Tasks"
            value={Math.random() * 100}
            showDecimal
            amplitude={4}
            frequency={2}
            animationTime={2000}
            animationWavesTime={2250}
            gradient={{
              type: 1,
              x1: 0,
              x2: 0,
              y1: 100,
              y2: 0,
              stops,
            }}
            postfix="%"
            legendFontSize={0.1}
          />
      </div>
    );
  }
}
render(<ChartLiquid />, document.getElementById('app'));

LiquidChart PropTypes

Name Type Default Description
Width number null The width of the chart, used if responsive is false
height number null The width of the chart, used if responsive is false
responsive bool true If set to true then the element will fill out into parent container, and resize on window dimension change
Value number 0 The value, tops at 100 and 0 is the minimum
animationWavesTime number null The speed of the wave animation, going back and forth
animationTime number 2000 milliseconds for animation when updating value
animationEase string 'easeCubicInOut' The name of the d3 easing function, other values like, easeBack, easeBackInOut, easeSinInOut, easeExpInOut. See d3 easing page for more ideas.
outerBound number 0.9 This is the outerRadius of the chart where 1 would be 100% of the radius and 0 would be 0% of the radius..
innerBound number 0.8 The innerwidth of the outerpath surronding the liquid, again 0.8 would be 80% of the radius.
margin number 0.025 The margin between the outer path and the liquid, here 0.025 would be 2.5%
amplitude number 4 The Amplitude X * sine(frequency) part of the formula
frequency number 2 The frequency, how many full circles are in the chart.
waveScaleLimit bool true This is in the original, this will create a scale that limits the wave height close to 0 or 100
outerStyle shape { fill: 'rgb(23,139,202)'} The style of the outerarc fill and stroke
liquidStyle shape { fill: 'rgb(23, 139, 202)'} The style of the liquid, fill and stroke
dryStyle shape {fill: 'rgb(164, 219, 248)'} The style of the number that is not in the liquid, fill and stroke
wetStyle shape {fill: 'rgb(4, 86, 129)'} The style of the number that is in the liquid, fill and stroke
fontSizes shape The sizes of the fonts in ratio to the radius.
showDecimal bool false If this is set then the decimal place is shown
postfix string null The symbol that goes in the last tspan placeholder

Animation

There are two kinds of animation, the value animation and the back and forth animation. To set the animation you only need to set either the animationTime or the animationEase for value transitions. To set the back and forth animation you need to set the animationWavesTime prop.

fontSizes

Sets the fontsize of the tspans. The values are fractions of the radius.

const fontSize = {
  value: 0.6,
  decimal: 0.3,
  postfix: 0.1,
  legend: 0.1,
};

CSS

You can add your own css to the component by targeting the classes that are set.

For an example if I would like to change the font type and the positioning I could do something like this

  .liquid-text {
    transform: translate(0, 40px);
    font-family: Roboto;
  }
