## Usage

```ts
import { Component, ViewChild } from '@angular/core';
import { WidgetTopOffersByClientsLastNyearsComponent } from './widget-top-offers-by-clients-last-nyears.component';

@Component({
  selector: 'app-dashboard-page',
  template: `
    <app-widget-top-offers-by-clients-last-nyears
      #topOffersWidget>
    </app-widget-top-offers-by-clients-last-nyears>
  `
})
export class DashboardPageComponent {
  @ViewChild('topOffersWidget')
  topOffersWidget?: WidgetTopOffersByClientsLastNyearsComponent;

  refreshTopOffers(): void {
    this.topOffersWidget?.getDashboardData();
  }
}
```

## AI Coding Instructions

- Let Angular invoke `ngOnInit` and `ngOnChanges`; do not call lifecycle hooks directly from application code.
- Keep data loading in `getDashboardData()` and process returned data through `afterResponse()`.
- Preserve the existing `setChaching()` and `getChaching()` method names when working with cached widget state.
- Initialize chart event wiring in `onChartInit()` and keep chart click behavior in `onPlannedVisitsChartClick()`.
- When adding filter inputs or dashboard controls, route updates through `onValueChanged()` so the widget reloads consistently.
