By default it's automatically calculated as 1/14 of size but you may set your own number Default: "auto" | | show-percent | Boolean | Show loaded percentage inside circle. If inner-text property is set then percentage will not be shown. 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. | | redraw(props) | It will update component. Param is a JSON object, you must used props) |

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");
this.$refs.myUniqueID.redraw({ animation: { duration: 5000 }, size: 150 });
