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"

- "#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 }

- { image: imageInstance }
- { color: "lime", image: "http://i.imgur.com/pT0i89v.png" }

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");
