ViewerChartOptions

Purpose

This module defines Prism-based event classes for chart viewer operations, enabling loosely-coupled communication between components in the viewer subsystem. Events cover zoom reset, cursor display/clearing, PDF export, and axis/options changes. Uses the older Microsoft.Practices.Prism.Events namespace (Prism 4.x or earlier).

Public Interface

ResetZoomChangedEvent

• Inherits CompositePresentationEvent<bool> - Event payload is a boolean.

CursorShowChangedEvent

• Inherits CompositePresentationEvent<bool> - Event payload is a boolean.

CursorsClearChangedEvent

• Inherits CompositePresentationEvent<bool> - Event payload is a boolean.

CursorShowMinMaxChangedEvent

• Inherits CompositePresentationEvent<bool> - Event payload is a boolean.

CursorsAlailableChangedEvent

• Inherits CompositePresentationEvent<bool> - Event payload is a boolean. Note: typo in class name ("Alailable" vs "Available").

SaveToPDFRequestedEvent

• Inherits CompositePresentationEvent<string> - Event payload is a string (likely file path).

ChartAxisChangedEvent

• Inherits CompositePresentationEvent<ChartAxisChangedEventArg> - Event payload is ChartAxisChangedEventArg.

ChartAxisChangedEventArg

• IBaseViewModel ParentVM { get; set; } - Parent view model reference.
• string Axis { get; set; } - Axis identifier.
• double MinValue { get; set; } - Minimum axis value.
• double MaxValue { get; set; } - Maximum axis value.

ChartOptionsChangedEvent

• Inherits CompositePresentationEvent<ChartOptionsChangedEventArg> - Event payload is ChartOptionsChangedEventArg.

ChartOptionsChangedEventArg

• IBaseViewModel ParentVM { get; set; } - Parent view model reference.
• IChartOptionsModel Model { get; set; } - Chart options model.
• string ChartType { get; set; } - Chart type identifier.

Invariants

• All events inherit from CompositePresentationEvent<T> and are empty classes (no additional members).
• Event args classes (ChartAxisChangedEventArg, ChartOptionsChangedEventArg) are mutable POCOs with public getters and setters.
• The `
