Documentation: ChartOptionsView

1. Purpose

ChartOptionsView is a WPF view component that provides user interface logic for configuring chart display options. It implements the IChartOptionsView interface, serving as the visual layer for chart-related settings within the DTS Viewer application. The view exposes available filter class options that can be applied to sensor data visualization.

---

2. Public Interface

ChartOptionsView() (Constructor)

Signature: public ChartOptionsView()

Initializes a new instance of the ChartOptionsView class. Calls InitializeComponent() to load the associated XAML layout.

---

AvailableCFC (Property)

Signature: public List<IFilterClass> AvailableCFC { get; }

A read-only property that returns the list of available filter classes (CFC = Constant Fraction Classes, per FB 13120).

Behavior: Each access instantiates a new AnalogSettingDefaults object and returns its FilterOptions property.

Returns: List<IFilterClass> containing the available filter options.

---

3. Invariants

• The AvailableCFC property getter always creates a new instance of AnalogSettingDefaults on every access; it does not cache or reuse the object.
• The view always implements IChartOptionsView as its contract with the rest of the system.
• The XAML component (referenced via InitializeComponent()) is expected to be present and properly compiled as part of the partial class definition.

4. Dependencies

This module depends on:

Namespace	Type Used
DTS.Common.Interface	IChartOptionsView
DTS.Common.Interface.Sensors.SoftwareFilters	IFilterClass
DTS.SensorDB	AnalogSettingDefaults

What depends on this module:

Unclear from source alone. The IChartOptionsView interface suggests a presenter, view model, or controller consumes this view, but no direct consumers are visible in this file.

5. Gotchas

1. Instance creation on every property access: The AvailableCFC property instantiates a new AnalogSettingDefaults object on every call. If this property is data-bound in XAML and accessed frequently (e.g., by a UI update loop), it could create unnecessary object allocations and GC pressure. Consider whether caching would be appropriate.

2. FB 13120 reference: The XML comment references "FB 13120" (likely a feature/bug tracking identifier). The business context for why this property exists or what specific requirement it addresses is not clear from source alone.

3. Partial class definition: This is a partial class. The XAML file (ChartOptionsView.xaml) defines additional structure (base class, visual elements) that is not visible here. The actual base class (likely UserControl or similar) is defined in the XAML.
