If inner-text property is set then percentage will not be shown. Default : true | | show-legend | Boolean | Shows percentage text Default : true | | legendClass | String | Classes for percentage text Default : true |

Events

Events emitted by the component to the parent.

| Event Name | Description | | --------------------------------------------- | ----------------------------------------------------- | | vue-circle-init(event) | This event is emmited after the circle is initialized | | vue-circle-progress(event,progress,stepValue) | This event is emitted on every progress step | | vue-circle-end(event) | This event is emitted after completing progress |

Methods

Methods you can call on the component.

| Method | Description | | --------------------- | ------------------------------------------------------------------------------------------------- | | updateProgress(value) | It will update component progress value and animate the change. It doesn't redraw the widget. | | updateFill(fill) | It will update component fill color. |

Using Methods

Methods can be called from your parent component by making use of the special tag "ref".

When you initialize the component add a unique ID to the component using the ref tag, like this

<vue-circle ref="myUniqueID"></vue-circle>

Then from your parent Vue instance, you can call the methods by using the following:

this.$refs.myUniqueID.updateProgress(21)
this.$refs.myUniqueID.updateFill('#ff1e41')
