Pure.Chart.RichRelationalModel

Concrete immutable record implementations of the rich relational chart model for the Pure ecosystem.

Overview

Pure.Chart.RichRelationalModel provides sealed record implementations for chart domain entities that combine both the structural (model) and relational aspects of a chart into a single strongly-typed, immutable object. Each record implements a corresponding interface from Pure.Chart.RichRelationalModel.Abstractions and exposes primitive-typed properties via the Pure.Primitives.Abstractions contracts (IGuid, IString).

A "rich relational" model is one that carries not only foreign-key identifiers but also the fully resolved navigation objects — e.g. a ChartRichRelationalModel holds both TypeId (IGuid) and Type (IChartType), both XAxisId/YAxisId and the resolved IAxis instances.

Types

All types live in the Pure.Chart.RichRelationalModel namespace.

Type	Implements	Properties
ChartRichRelationalModel	IChartRichRelationalModel	Id, Title, Description, TypeId, Type, XAxisId, XAxis, YAxisId, YAxis, Series
AxisRichRelationalModel	IAxisRichRelationalModel	Id, Legend
ChartSeriesRichRelationalModel	IChartSeriesRichRelationalModel	Id, ChartId, Legend, XAxisSource, YAxisSource
ChartTypeRichRelationalModel	IChartTypeRichRelationalModel	Id, Name

Each record provides two constructors:

• Copy constructor — accepts the corresponding rich relational interface, copies all properties.
• Full constructor — accepts each property individually for explicit construction.

Design Principles

• Immutable — all properties are init-only; records enforce value equality.
• Composable — each type implements the interface hierarchy from Pure.Chart.RichRelationalModel.Abstractions, which itself composes IChart* and IChartRelationalModel* interfaces.
• AOT-compatible — the library is trimming- and AOT-safe (IsAotCompatible = true).

Dependencies

• Pure.Chart.RichRelationalModel.Abstractions — interface contracts for IChartRichRelationalModel, IAxisRichRelationalModel, IChartSeriesRichRelationalModel, and IChartTypeRichRelationalModel

Target Frameworks

• .NET 7
• .NET 8

Installation

dotnet add package Pure.Chart.RichRelationalModel

Usage

using Pure.Chart.RichRelationalModel;

// Construct from individual primitives
IChartRichRelationalModel chart = new ChartRichRelationalModel(
    id: myGuid,
    title: myTitle,
    description: myDescription,
    typeId: typeGuid,
    type: new ChartTypeRichRelationalModel(typeGuid, typeName),
    xAxisId: xGuid,
    xAxis: new AxisRichRelationalModel(xGuid, xLegend),
    yAxisId: yGuid,
    yAxis: new AxisRichRelationalModel(yGuid, yLegend),
    series: chartSeriesCollection
);

// Or copy-construct from any IChartRichRelationalModel
IChartRichRelationalModel copy = new ChartRichRelationalModel(existingChart);
