Props

Follwing props are used while initialization

Note : Only progress is a required prop. Others are optional

Prop Name	Type	Description
progress `(required)`	Number	Total progress of circle (filled area)
size	Number	Size of circle Default : `200`
reverse	Boolean	Reverse animation and arc draw Default:`false`
line-cap	String	Arc line cap: "butt", "round" or "square" `Default: "butt"`
fill	Object	The arc fill config. You may specify next: - `"#ff1e41"` - `{ color: "#ff1e41" }` - `{ color: 'rgba(255, 255, 255, .3)' }` - `{ gradient: ["red", "green", "blue"] }` - `{ gradient: [["red", .2], ["green", .3], ["blue", .8]] }` - `{ gradient: [ ... ], gradientAngle: Math.PI / 4 }` - `{ gradient: [ ... ], gradientDirection: [x0, y0, x1, y1] }` - `{ image: "http://i.imgur.com/pT0i89v.png" }` - `{ image: imageInstance }` - `{ color: "lime", image: "http://i.imgur.com/pT0i89v.png" }` Default: `{ gradient: ["#3aeabb", "#fdd250"] }`
empty-fill	String	Color of the "empty" arc. Only a color fill supported by now Default: `"rgba(0, 0, 0, .1)"`
animation	Mixed	Animation config. See jQuery animations. You may also set it to `false` Default: `{ duration: 1200, easing: "circleProgressEasing" }` `"circleProgressEasing"` is just a ease-in-out-cubic easing
animation-start-value	Number	Default animation starts at `0.0` and ends at specified `value`. Let's call this direct animation. If you want to make reversed animation then you should set `animationStartValue` to `1.0`. Also you may specify any other value from `0.0` to `1.0` Default: `0.0`
start-angle	Number	Initial angle (for `0` value) Default: `-Math.PI`
insert-mode	String	Canvas insertion mode: append or prepend it into the parent element Default: `"prepend"`
thickness	Number	Width of the arc. 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.

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");
