react-d3-speedometer
react-d3-speedometer is a react component library for showing speedometer like gauge using d3.
Usage:
NPM:
npm install --save react-d3-speedometer
Yarn:
yarn add react-d3-speedometer
// import the component
import ReactSpeedometer from "react-d3-speedometer"
// and just use it
<ReactSpeedometer />
Configuration Options:
| prop | type | default | comments |
| ------------|:--------------:| --------:| ---------|
| value | Number | 0 | Make sure your value is between your minValue
and maxValue
|
| minValue | Number | 0 | |
| maxValue | Number | 1000 | |
| segments | Number | 5 | Number of segments in the speedometer. Please note, segments
is calculated with d3-ticks which is an approximate count that is uniformly spaced between min and max. Please refer to d3-ticks and d3-array ticks for more detailed info. |
| maxSegmentLabels | Number | value from 'segments' prop | Limit the number of segment labels to displayed. This is useful for acheiving a gradient effect by giving arbitrary large number of segments
and limiting the labels with this prop. See Live Example. Please note, maxSegmentLabels
is calculated with d3-ticks which is an approximate count that is uniformly spaced between min and max. Please refer to d3-ticks and d3-array ticks for more detailed info. |
| forceRender | Boolean | false | After initial rendering/mounting, when props change, only the value
is changed and animated to maintain smooth visualization. But, if you want to force rerender the whole component like change in segments, colors, dimensions etc, you can use this option to force rerender of the whole component on props change. |
| width | Number | 300 | diameter of the speedometer and the width of the svg element |
| height | Number | 300 | height of the svg element. Height of the speedometer is always half the width since it is a semi-circle. For fluid width, please refere to fluidWidth
config |
| dimensionUnit | String | px | Default to px
for width/height
. Possible values - "em" , "ex" , "px" , "in" , "cm" , "mm" , "pt" , ,"pc"
... Please refer to specification for more details |
| fluidWidth | Boolean | false | If true
takes the width of the parent component. See Live Example for more details |
| needleColor | String | steelblue | Should be a valid color code - colorname, hexadecimal name or rgb value. Should be a valid input for d3.interpolateHsl |
| startColor | String | #FF471A | Should be a valid color code - colorname, hexadecimal name or rgb value. Should be a valid input for d3.interpolateHsl |
| endColor | String | #33CC33 | Should be a valid color code - colorname, hexadecimal name or rgb value. Should be a valid input for d3.interpolateHsl |
| segmentColors | Array (of colors) | [] | Custom segment colors can be given with this option. Should be an array of valid color codes. If this option is given startColor and endColor options will be ignored. |
| needleTransition | String | easeQuadInOut | d3-easing-identifiers - easeLinear, easeQuadIn, easeQuadOut, easeQuadInOut, easeCubicIn, easeCubicOut, easeCubicInOut, easePolyIn, easePolyOut, easePolyInOut, easeSinIn, easeSinOut, easeSinInOut, easeExpIn, easeExpOut, easeExpInOut, easeCircleIn, easeCircleOut, easeCircleInOut, easeBounceIn, easeBounceOut, easeBounceInOut, easeBackIn, easeBackOut, easeBackInOut, easeElasticIn, easeElasticOut, easeElasticInOut, easeElastic |
| needleTransitionDuration | Number | 500 | Time in milliseconds. |
| needleHeightRatio | Float (between 0 and 1) | 0.9 | Control the height of the needle by giving a number/float between 0
and 1
. Default height ratio is 0.9
. |
| ringWidth | Number | 60 | Width of the speedometer ring. |
| textColor | String | #666 | Should be a valid color code - colorname, hexadecimal name or rgb value. Used for both showing the current value and the segment values |
| valueFormat | String | | should be a valid format for d3-format. By default, no formatter is used. You can use a valid d3 format identifier (for eg: d
to convert float to integers), to format the values. Note: This formatter affects all the values (current value, segment values) displayed in the speedometer |
| currentValueText | String | ${value} | Should be provided a string which should have ${value} placeholder which will be replaced with current value. By default, current value is shown (formatted with valueFormat
). For example, if current Value is 333 if you would like to show Current Value: 333
, you should provide a string Current Value: ${value}
. See Live Example |
| currentValuePlaceholderStyle | String | ${value} | Should be provided a placeholder string which will be replaced with current value in currentValueTextProp
. For example: you can use ruby like interpolation by giving following props - <ReactSpeedometer currentValueText="Current Value: #{value}" currentValuePlaceholderStyle={"#{value}"} />
. This is also helpful if you face no-template-curly-in-string
eslint warnings and would like to use different placeholder for current value |
| customSegmentStops | Array | [] | Array of values starting at min
value, and ending at max
value. This configuration is useful if you would like to split the segments at custom points or have unequal segments at preferred values. If the values does not begin and end with min
and max
value respectively, an error will be thrown. This configuration will override segments
prop, since total number of segments will be length - 1
of customSegmentProps
. For example, [0, 50, 75, 100]
value will have three segments - 0-50
, 50-75
, 75-100
. See Live Example |
| labelFontSize | String | 14px | Font size for segment labels/legends |
| valueTextFontSize | String | 16px | Font size for current value text |
| paddingHorizontal | Number | 0 | Provides right/left space for the label text. Takes a number (without explicit unit, unit will be taken from dimensionUnit config which defaults to px). Helpful when using a bigger font size for label texts. |
| paddingVertical | Number | 0 | Provides top/bottom space for the current value label text below the needle. Takes a number (without explicit unit, unit will be taken from dimensionUnit config which defaults to px). Helpful when using a bigger font size for label texts. |

Default with no config - Live Example
<ReactSpeedometer />
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 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}

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}
/>
