Source: Frontend/src/app/components/dashboard/dashboard-libary/widgets/widget-principals-tendancy/widget-principals-tendancy.component.ts (line 17)

Part of: Frontend

WidgetPrincipalsTendancyComponent manages dashboard data and chart presentation for principal tendency information. It checks feature subscription access, initializes the chart, and derives values, colors, and chart height for rendering.

Extends: BaseWidgetComponent

Implements: OnInit

Methods

Properties

Where it refuses work

• WidgetPrincipalsTendancyComponent stops the work with an early return when this.dashboardLibraryService.checkFeatureSubscription(this.widget.chartEnumId).
• WidgetPrincipalsTendancyComponent stops the work with an early return when value > 150.

Usage

ts
import { Component, ViewChild } from '@angular/core';
import { WidgetPrincipalsTendancyComponent } from './widget-principals-tendancy.component';

@Component({
  selector: 'app-dashboard-host',
  template: `
    <app-widget-principals-tendancy
      #principalsWidget>
    </app-widget-principals-tendancy>
  `
})
export class DashboardHostComponent {
  @ViewChild('principalsWidget')
  principalsWidget!: WidgetPrincipalsTendancyComponent;

  refreshWidget(): void {
    if (this.principalsWidget.checkFeatureSubscription()) {
      this.principalsWidget.getDashboardData();
      this.principalsWidget.onChartInit();
    }
  }
}

AI Coding Instructions

• Keep feature-access checks through checkFeatureSubscription() before requesting or rendering subscription-dependent dashboard data.
• Call getDashboardData() as part of component initialization or refresh flows; avoid duplicating its data-loading logic in parent components.
• Keep chart setup in onChartInit() and use setValue(), setColor(), and chartHeight() for chart-specific display state.
• Preserve Angular lifecycle behavior by keeping initialization work in ngOnInit() rather than requiring callers to construct the component directly.
