# Documentation: DTS.Common.Interface.Graphs

## 1. Purpose

This module defines the core data contracts for graph configuration within the DTS system. It provides two interfaces—`IGraphRecord` and `IGraph`—that model graph definitions persisted in a database, including axis bounds configuration, channel associations, and threshold lines. `IGraphRecord` represents the raw database record structure, while `IGraph` extends it with runtime operations for channel management and XML serialization. These interfaces serve as the abstraction layer between graph persistence and graph rendering/logic components.

## 2. Public Interface

### IGraphRecord

Base interface describing a database record for a graph.

| Property | Type | Description |
|----------|------|-------------|
| `GraphId` | `int` | Database primary key for the graph. |
| `TestSetupId` | `int` | Foreign key linking the graph to a test setup. |
| `GraphName` | `string` | Display name of the graph. Constrained to 50 characters via `[MaxLength(50)]`. |
| `GraphDescription` | `string` | Description text for the graph. Constrained to 50 characters via `[MaxLength(50)]`. |
| `ChannelsString` | `string` | Serialized representation of all channels in the graph. Constrained to 2048 characters via `[MaxLength(2048)]`. |
| `UseDomainMin` | `bool` | Flag indicating whether the domain (X) axis has a minimum bound. |
| `DomainMin` | `double` | Minimum value for the domain axis. Only meaningful when `UseDomainMin` is `true`. |
| `UseDomainMax` | `bool` | Flag indicating whether the domain (X) axis has a maximum bound. |
| `DomainMax` | `double` | Maximum value for the domain axis. Only meaningful when `UseDomainMax` is `true`. |
| `UseRangeMin` | `bool` | Flag indicating whether the range (Y) axis has a minimum bound. |
| `RangeMin` | `double` | Minimum value for the range axis. Only meaningful when `UseRangeMin` is `true`. |
| `UseRangeMax` | `bool` | Flag indicating whether the range (Y) axis has a maximum bound. |
| `RangeMax` | `double` | Maximum value for the range axis. Only meaningful when `UseRangeMax` is `true`. |
| `ThresholdsString` | `string` | Serialized representation of threshold lines to display on the graph. Constrained to 2048
