# ChartOptions

### Purpose
This module defines enumeration types used for chart configuration options in the DTS Viewer component. It provides strongly-typed options for time unit display, data filtering, Y-axis range scaling, device wake methods, and chart unit types. Each enum is designed for use with the Xceed WPF Toolkit PropertyGrid, featuring `Description` attributes for display text and `IItemsSource` implementations for dropdown population.

### Public Interface

**TimeUnitTypeEnum** - Enum defining time unit display options.
- `MS = 0` - Milliseconds, displayed as "ms"
- `Seconds = 1` - Seconds, displayed as "Seconds"

**TimeUnitTypeItemSource** - Implements `IItemsSource`. Provides `GetValues()` method returning `ItemCollection` via `EnumUtil.GetValuesList<TimeUnitTypeEnum>()`.

**FilterOptionEnum** - Enum defining data filtering modes.
- `Unfiltered = 0` - No filtering applied
- `TestSetupDefault = 1` - Use test setup default filter settings
- `Custom = 2` - User-defined custom filtering

**FilterOptionEnumItemSource** - Implements `IItemsSource`. Provides `GetValues()` method returning `ItemCollection` via `EnumUtil.GetValuesList<FilterOptionEnum>()`.

**YRangeScaleEnum** -
