Demo

Click here for the Angular 1.x version

Install

First you have to install the module through npm:

npm install angular-svg-round-progressbar --save

Afterwards you need to import the RoundProgressModule in your module:

import {NgModule} from '@angular/core';
import {RoundProgressModule} from 'angular-svg-round-progressbar';

@NgModule({
  imports: [RoundProgressModule]
})
export class YourModule {};

If you're using SystemJS as your module loader, there is also a UMD bundle at ./node_modules/angular-svg-round-progressbar/bundles/angular-svg-round-progressbar.umd.js.

Options

| Name | Description | Required | Default value | Possible values | | --- | --- | --- | --- | --- | | current | The current progress. Limited by the max option. | Yes | undefined | number | | max | The progress' maximum value. | Yes | undefined | number | | radius | Radius of the circle. | No | 125 | number | | color | The color of the current value on the circle. | No | #45ccce | string | | background | Color of the circle's background. | No | #eaeaea | string | | stroke | Specifies the circle's thickness. | No | 15 | number | | semicircle | Whether the progressbar should be a full circle or a semicircle. | No | false | boolean | | clockwise | Whether the progressbar should rotate clockwise or counter-clockwise. | No | true | boolean | | responsive | Whether the progressbar should fit inside its parent container. Note Turning this option on will override the specified radius in order to make the circle fit in its parent. The radius to stroke ratio won't change. | No | false | boolean | | rounded | Whether the current progress ending should be rounded or straight. | No | false | boolean | | duration | The duration of the animation. Pass 0 for no animation. | No | 800 | number | | animationDelay | Milliseconds to wait before starting an animation. | No | 0 | number | | onRender | Callback function that gets executed every time the circle is animated. The function gets called with the current progress as it is being animated. | No | undefined | Function | | animation | The easing function that will be used when animating. | No | easeOutCubic | linearEase easeInQuad easeOutQuad easeInOutQuad easeInCubic easeOutCubic easeInOutCubic easeInQuart easeOutQuart easeInOutQuart easeInQuint easeOutQuint easeInOutQuint easeInSine easeOutSine easeInOutSine easeInExpo easeOutExpo easeInOutExpo easeInCirc easeOutCirc easeInOutCirc easeInElastic easeOutElastic easeInOutElastic easeInBack easeOutBack easeInOutBack easeInBounce easeOutBounce easeInOutBounce |

Minimal example:

<round-progress [current]="current" [max]="max"></round-progress>

Full example:

<round-progress
    [current]="current"
    [max]="max"
    [color]="'#45ccce'"
    [background]="'#eaeaea'"
    [radius]="125"
    [stroke]="20"
    [semicircle]="true"
    [rounded]="true"
    [clockwise]="false"
    [responsive]="false"
    [duration]="800"
    [animation]="'easeInOutQuart'"
    [animationDelay]="0"
    (onRender)="doSomethingWithCurrentValue($event)"></round-progress>

Configuring the default values

The module comes with some pre-configured options for things like colors, size, stroke etc. If these don't match your app's design, you can change the global defaults by providing a new value for the ROUND_PROGRESS_DEFAULTS injection token. Whenever an option isn't defined on a round-progress element, it's value will be taken from the defaults.

import {NgModule} from '@angular/core';
import {
  RoundProgressModule,
  RoundProgressConfig,
  ROUND_PROGRESS_DEFAULTS
  } from 'angular-svg-round-progressbar';

@NgModule({
  imports: [RoundProgressModule],
  providers: [{
    provide: ROUND_PROGRESS_DEFAULTS,
    useValue: {
      color: '#f00',
      background: '#0f0'
    }
  }]
})
export class YourModule {};

Browser support

• yarn to install development dependencies.
• yarn lint to lint the source files.
• yarn start to run a development server. Go to localhost:4200 to see the demo.
• yarn build-lib to build the library in production mode.
• yarn build-demo to build the demo in production mode.
• yarn release-lib to build the library and release it to npm.
• yarn release-demo to build the demo and deploy it to GitHub Pages.
