PSDReportMainViewModel Documentation

1. Purpose

PSDReportMainViewModel serves as the primary view model coordinator for the PSD (Power Spectral Density) Report module within the DTS Viewer application. It manages navigation regions, orchestrates view loading, handles user interaction requests, and coordinates event-driven communication between child views (graphs, tests, charts, settings, and data selection components). This class acts as the central hub binding the PSD report UI regions to their respective views and view models.

Constructor

public PSDReportMainViewModel(IRegionManager regionManager, IEventAggregator eventAggregator, IUnityContainer unityContainer)
