# PieChart
An animated pie chart component, displaying all changes with smooth transitions.

The library has been developed with Angular 6. It should work with older versions of Angular too, but this isn't tested yet.

This repository is maintained by volunteers of [OPITZ CONSULTING Deutschland GmbH](https://www.opitz-consulting.com).


There is a demo component `PieChartDemoComponent` in this repository at https://github.com/opitzconsulting/ngx-d3.

```bash
npm install @opitzconsulting/pie-chart
```

In your application root module definition add `PieChartModule`.
```typescript
import { PieChartModule } from '@opitzconsulting/pie-chart';
@NgModule({
  bootstrap: [ /* ... */ ],
  declarations: [ /* ... */ ],
  imports: [
    /* ... */
    PieChartModule
  ]
})
export class AppModule {}
```

In your components template add `oc-pie-chart` tag.
```html
<oc-pie-chart [data]="pieChartData" width="250" height="250"></oc-pie-chart>
```

In your component class you can declare the data:
```typescript
import { PieChartData } from 'oc-pie-chart';
/* ... */
public pieChartData: Array<PieChartData>: Array<PieChartData> = [
  { caption: 'apples', value: 10, color: 'green' },
  { caption: 'oranges', value: 20, color: 'orange' },
  { caption: 'bananas', value: 30, color: 'yellow' }
];
```

**Properties:**
