![vue-speedometer](https://raw.githubusercontent.com/palerdot/vue-speedometer/master/speedo.gif)

**IMPORTANT** `v3.0` is released which is a complete rewrite with composition api/SFC (single file components). Minimum required vue version is `v3.3`. If you are using Vue 3 composition api, please upgrade to `v3`

Note: v2.x is still compatible with `Vue 3`. Please use latest v1.x (v1.8.0 at the time of writing) if you are using `Vue 2`.

## Usage:

**pnpm:**

`pnpm add vue-speedometer` 

**Yarn:**

`yarn add vue-speedometer` 

**NPM:**

`npm install --save vue-speedometer` 

```javascript

// import the component

import VueSpeedometer from "vue-speedometer"

// and use it in your component like

  

```

### Slim Build (Experimental):

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`. 

```javascript

// sample slim build usage

import VueSpeedometer from "vue-speedometer/slim"

// and use it

```

## Examples:

You can view [Live Examples here](https://palerdot.in/vue-speedometer/)

## 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](https://github.com/d3/d3-scale/blob/master/README.md#continuous_ticks) and [d3-array ticks](https://github.com/d3/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](https://palerdot.in/vue-speedometer/?path=/story/vue-speedometer--gradient-effect-with-large-number-of-segments-and-maxsegmentlabels-config). 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](https://github.com/d3/d3-scale/blob/master/README.md#continuous_ticks) and [d3-array ticks](https://github.com/d3/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](https://developer.mozilla.org/en-US/docs/Web/SVG/Content_type#Length) for more details |

| fluidWidth  | Boolean        | false    | If `true` takes the width of the parent component. See [Live Example](https://palerdot.in/vue-speedometer/?selectedStory=Fluid%20Width%20view&full=0&down=0&left=1&panelRight=0&downPanel=kadirahq%2Fstorybook-addon-actions%2Factions-panel) 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](https://github.com/d3/d3-interpolate#interpolateHsl)   |

| startColor | String         | #FF471A | Should be a valid color code - colorname, hexadecimal name or rgb value. Should be a valid input for [d3.interpolateHsl](https://github.com/d3/d3-interpolate#interpolateHsl)   |

| endColor | String         |  #33CC33 | Should be a valid color code - colorname, hexadecimal name or rgb value. Should be a valid input for [d3.interpolateHsl](https://github.com/d3/d3-interpolate#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](https://github.com/d3/d3-ease) - 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 'vue-speedometer'` and use it like `Transition.easeElastic`. This works for both JS and Typescript. For `type(script)` definitions, please refer [here](./src/index.d.ts). |

| 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](https://github.com/d3/d3-format#locale_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](https://palerdot.in/vue-speedometer/?selectedKind=vue-speedometer&selectedStory=Custom%20Current%20Value%20Text&full=0&down=1&left=1&panelRight=0) |

| 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 - ``. 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](https://palerdot.in/vue-speedometer/?path=/story/vue-speedometer--custom-segment-stops) |

| customSegmentLabels | Array`` | [] | Takes an array of `CustomSegmentLabel` objects. 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 'vue-speedometer'`, and use it like `CustomSegmentLabelPosition.Inside / CustomSegmentLabelPosition.Outside`. This works for both JS and Typescript. For `type(script)` definitions, please refer [here](./src/index.d.ts).  |

| 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      | Vue Speedometer     | SVG aria-label property for Accessibility purposes |

### FAQ

- Please refer this [comment](https://github.com/vuejs/vue-cli/issues/1875#issuecomment-408739414) if you run into `vue cli you are using the runtime only build of vue where the template compiler is not available` message when running from your local setup bootstrapped with `vue-cli`. Basically create a `vue.config.js`

```javascript

// vue.config.js

module.exports = {

  runtimeCompiler: true

}

```
