`WidgetTopOffersByMarketSegmentsLastNyearsComponent` is an Angular dashboard widget that loads and displays top offers grouped by market segment across a selected year range. It reacts to lifecycle and value changes, initializes chart behavior, handles chart clicks, assigns year colors, and stores or retrieves cached widget state.

import { WidgetTopOffersByMarketSegmentsLastNyearsComponent } from './widget-top-offers-by-market-segments-last-nyears.component';

@Component({
  selector: 'app-dashboard-host',
  template: `
    <app-widget-top-offers-by-market-segments-last-nyears>
    </app-widget-top-offers-by-market-segments-last-nyears>
  `
})
export class DashboardHostComponent implements AfterViewInit {
  @ViewChild(WidgetTopOffersByMarketSegmentsLastNyearsComponent)
  offersWidget!: WidgetTopOffersByMarketSegmentsLastNyearsComponent;

  ngAfterViewInit(): void {
    this.offersWidget.getChaching();
    this.offersWidget.getDashboardData();
  }

  refreshOffers(): void {
    this.offersWidget.onValueChanged();
  }
}
```

## AI Coding Instructions

- Keep data loading in `getDashboardData()` and apply response-dependent state updates in `afterResponse()`.
- Call `setChaching()` when widget selections change so cached state matches the current chart state.
- Use `getChaching()` during initialization before requesting dashboard data when cached selections are supported.
- Keep chart setup in `onChartInit()` and route chart interaction handling through `onPlannedVisitsChartClick()`.
- Use `setYearColor()` for chart series colors rather than assigning year colors in multiple locations.
