Ports

Getting Started:

Install with yarn or npm.

Yarn:

yarn add react-d3-speedometer

npm:

npm install --save react-d3-speedometer

And, use it like

// import the component
import ReactSpeedometer from "react-d3-speedometer"
// and just use it
<ReactSpeedometer />

Slim Build:

There is a Slim build available without bundling d3. This project uses d3 micro bundles. If your project also uses d3 microbundles, you can opt for slim build. Necessary d3 dependencies required for slim build to work are - d3-array, d3-color, d3-ease, d3-format, d3-interpolate, d3-scale, d3-selection, d3-shape, d3-transition.

// sample slim build usage
import ReactSpeedometer from "react-d3-speedometer/slim"
// and use it
<ReactSpeedometer />

Live Examples

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 (JS) / Transition (TS)	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. There is a helper Object/Type 'Transtion', which you can import like `import { Transition } from 'react-d3-speedometer'` and use it like `Transition.easeElastic`. This works for both JS and Typescript. For `type(script)` definitions, please refer here.
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
segmentValueFormatter	Function	value => value	Custom segment values formatter function. This function is applied after 'valueFormat' prop if present.
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
customSegmentLabels	Array`<CustomSegmentLabel>`	[]	Takes an array of `CustomSegmentLabel` objects. Please note, the array length should match `segments` which is automatically calculated by `d3-ticks`. For more details, please check `segment` prop section. Each object has following keys for custom rendering of labels - `text`, `fontSize`, `color`, `position: OUTSIDE/INSIDE`. For `position`, there is a helper `CustomSegmentLabelPosition` Object/Type which you can import like `import { CustomSegmentLabelPosition } from 'react-d3-speedometer'`, and use it like `CustomSegmentLabelPosition.Inside / CustomSegmentLabelPosition.Outside`. This works for both JS and Typescript. For `type(script)` definitions, please refer here.
labelFontSize	String	14px	Font size for segment labels/legends
valueTextFontSize	String	16px	Font size for current value text
valueTextFontWeight	String	bold	Font weight for current value text. Any valid font weight identifier (500, bold etc) can be used.
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.
svgAriaLabel	String	React d3 speedometer	SVG aria-label property for Accessibility purposes
