Usage

Basic usage

With sane defaults in place, basic usage is as simple as passing a sections array of objects with a value prop to vc-donut component.

<template>
  <vc-donut :sections="sections">50%</vc-donut>
</template>
<script>
  export default {
    data() {
      return {
        sections: [{ value: 25 }, { value: 25 }, { value: 25 }, { value: 25 }]
      };
    }
  };
</script>

Usage with all the available props

<template>
  <vc-donut
    background="white" foreground="grey"
    :size="200" unit="px" :thickness="30"
    hasLegend legendPlacement="top"
    :sections="sections" :total="100"
  >
    <h1>100%</h1>
  </vc-donut>
</template>
<script>
  export default {
    data() {
      return {
        sections: [
          { label: 'Red section' value: 25, color: 'red' },
          { label: 'Green section' value: 25, color: 'green' },

  • Foreground color of the donut. This is the color that is shown for empty regions of the donut ring.

total

  • Specifies where the legend should be placed. Valid values are top, right, bottom and left.

sections

  • type: Array
  • default: []
  • An array of objects. Each object in the array represents one section. Every object must have a value property. Sum of all the sections' value should not exceed total, an error is thrown otherwise.
  • Object properties
    • value - Size of the section. Should be <= total.
    • color - Color of the section. vc-donut comes with 24 predefined colors, so this property is optional if you have <= 24 sections without the color property.
    • label - Name of this section. This is used in the legend as well as tooltip text.

Slots

default slot

If you want more control over text content of the chart, default slot can be used instead of the text prop.
