  1 | # react-gauge-chart
  2 | React component for displaying a gauge chart, using D3.js
  3 | 
  4 | # Usage
  5 | Install it by running `npm install react-gauge-chart`. Then to use it:
  6 | 
  7 | ```jsx
  8 | import GaugeChart from 'react-gauge-chart'
  9 | 
 10 | <GaugeChart id="gauge-chart1" />
 11 | ```
 12 | 
 13 | ## Examples
 14 | 
 15 | Check the demo below for live examples of the charts
 16 | 
 17 | #### To create a default chart
 18 | 
 19 | ```jsx
 20 | <GaugeChart id="gauge-chart1" />
 21 | ```
 22 | 
 23 | #### Chart with 20 levels and pointer at 86%
 24 | 
 25 | ```jsx
 26 | <GaugeChart id="gauge-chart2" 
 27 |   nrOfLevels={20} 
 28 |   percent={0.86} 
 29 | />
 30 | ```
 31 | 
 32 | #### Chart with custom colors and larger arc width
 33 | 
 34 | ```jsx
 35 | <GaugeChart id="gauge-chart3" 
 36 |   nrOfLevels={30} 
 37 |   colors={["#FF5F6D", "#FFC371"]} 
 38 |   arcWidth={0.3} 
 39 |   percent={0.37} 
 40 | />
 41 | ```
 42 | 
 43 | #### Chart with other corner radius and larger padding between arcs
 44 | 
 45 | ```jsx
 46 | <GaugeChart id="gauge-chart4" 
 47 |   nrOfLevels={10} 
 48 |   arcPadding={0.1} 
 49 |   cornerRadius={3} 
 50 |   percent={0.6} 
 51 | />
 52 | ```
 53 | 
 54 | #### Chart with custom arcs width
 55 | 
 56 | ```jsx
 57 | <GaugeChart id="gauge-chart5"
 58 |   nrOfLevels={420}
 59 |   arcsLength={[0.3, 0.5, 0.2]}
 60 |   colors={['#5BE12C', '#F5CD19', '#EA4228']}
 61 |   percent={0.37}
 62 |   arcPadding={0.02}
 63 | />
 64 | ```
 65 | 
 66 | #### Chart with disabled animation
 67 | 
 68 | ```jsx
 69 | <GaugeChart id="gauge-chart6" 
 70 |   animate={false} 
 71 |   nrOfLevels={15} 
 72 |   percent={0.56} 
 73 |   needleColor="#345243" 
 74 | />
 75 | ```
 76 | 
 77 | # Demo
 78 | https://martin36.github.io/react-gauge-chart/
 79 | 
 80 | # API
 81 | 
 82 | ## <GaugeChart />
 83 | 
 84 | ### Warning: Do not use the same `id` for multiple charts, as it will put multiple charts in the same container
 85 | 
 86 | #### Note: If you do any updates to the props of the chart, it will rerender with a different size (it's a bug). To prevent this set a fixed height for the chart e.g.
 87 | 
 88 | ```jsx
 89 | const chartStyle = {
 90 |   height: 250,
 91 | }
 92 | 
 93 | <GaugeChart id="gauge-chart1" style={chartStyle} />
 94 | 
 95 | ```
 96 | 
 97 | The props for the chart:
 98 | 
 99 | | Name            | PropType                    | Description                                                    | Default value          |

129 | ##### Colors for the chart
130 | 
131 | The colors could either be specified as an array of hex color values, such as `["#FF0000", "#00FF00", "#0000FF"]` where
132 | 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**
133 | must match the **number of levels** in the arc.
134 | If the number of colors does not match the number of levels, then the **first** and the **last** color from the colors array will
135 | be selected and the arcs will get colors that are interpolated between those. The interpolation is done using [d3.interpolateHsl](https://github.com/d3/d3-interpolate#interpolateHsl).
