    Basic usage

    With sane defaults in place, basic usage is as simple as passing a sections array with objects containing a value property. This will create a donut with 2 sections that take up 25% each.

      <vc-donut :sections="sections">Basic donut</vc-donut>
      export default {
        data() {
          return {
            sections: [{ value: 25 }, { value: 25 }]

    Usage with all the available props

        background="white" foreground="grey"
        :size="200" unit="px" :thickness="30"
        has-legend legend-placement="top"
        :sections="sections" :total="100"
        :start-angle="0" :auto-adjust-text-size="true"
      export default {
        data() {
          return {
            sections: [
              { label: 'Red section', value: 25, color: 'red' },
              { label: 'Green section', value: 25, color: 'green' },
              { label: 'Blue section', value: 25, color: 'blue' }
        methods: {
          handleSectionClick(section, event) {
            console.log(`${section.label} clicked.`);

    For brevity, only the section-click event is demonstrated in the above example. You can use all the other section-* events the same way.

    Using the component as a pie chart

    Making the component look like a pie chart is as simple as setting the thickness to 100.

        :sections="[{ value: 35 }, { value: 15 }, { value: 15 }, { value: 35 }]"

    Note: setting thickness to 100 will completely hide the diagram's text or slot content. The content will still be present in the DOM, however it won't be visible for obvious reasons.



    Prop Type Required Default Description
    size Number No 250 Diameter of the donut. Can be any positive value.
    unit String No 'px' Unit to use for size. Can be any valid CSS unit. Use % to make the donut responsive.
    thickness Number No 20 Percent thickness of the donut ring relative to size. Can be any positive value between 0-100 (inclusive). Set this to 0 to draw a pie chart instead.
    text String No Text to show in the middle of the donut. This can also be provided through the default slot.
    background String No '#ffffff' Background color of the donut. In most cases, this should be the background color of the parent element.
    foreground String No '#eeeeee' Foreground color of the donut. This is the color that is shown for empty region of the donut ring.
    start-angle Number No 0 Angle measure in degrees where the first section should start.
    total Number No 100 Total for calculating the percentage for each section.
    has-legend Boolean No false Whether the donut should have a legend.
    legend-placement String No 'bottom' Where the legend should be placed. Valid values are top, right, bottom and left. Doesn't have an effect if has-legend is not true.
    auto-adjust-text-size Boolean No true Whether the font-size of the donut content is calculated automatically to fit the available space.
    sections Array No [] An array of objects. Each object in the array represents a section.
    section.value Number Yes Value of the section. The component determines what percent of the donut should be taken by a section based on this value and the total prop. Sum of all the sections' value should not exceed total, an error is thrown otherwise.
    section.color String Read description Read description Color of the section. The component comes with 24 predefined colors, so this property is optional if you have <= 24 sections without the color property.
    section.label String No 'Section <section number>' Name of the section. This is used in the legend as well as the tooltip text of the section.


    All the section-* listeners are called with the section object on which the event occurred and the native Event object as arguments respectively. Consider adding a custom property (eg: name) to the section objects to uniquely identify them.

    Event Parameter Description
    section-click section, event Emitted when a section is clicked.
    section-mouseenter section, event Emitted when the mouseenter event occurs on a section.
    section-mouseleave section, event Emitted when the mouseleave event occurs on a section.
    section-mouseover section, event Emitted when the mouseover event occurs on a section.
    section-mouseout section, event Emitted when the mouseout event occurs on a section.
    section-mousemove section, event Emitted when the mousemove event occurs on a section.


    Slot Description
    default slot If you want more control over the content of the chart, default slot can be used instead of the text prop.
    legend Slot for plugging in your own legend.
