Pure.Chart.Model.Abstractions

Chart model interfaces for the Pure ecosystem — immutable, composable abstractions over chart data structures.

Overview

Pure.Chart.Model.Abstractions defines a set of minimal, read-only interfaces that represent the structural components of a chart. Each interface exposes only getters — no mutation, no side effects. All string properties are typed as IString from Pure.Primitives.Abstractions, keeping the model decoupled from concrete string representations.

Interfaces

Interface	Namespace	Description
IChart	Pure.Chart.Model.Abstractions	Root chart model — title, description, type, axes, and series
IChartType	Pure.Chart.Model.Abstractions	Named category of chart (e.g. bar, line, pie)
IChartSeries	Pure.Chart.Model.Abstractions	A single data series — legend label and axis source bindings
IAxis	Pure.Chart.Model.Abstractions	A chart axis with a legend label

Design Principles

• Immutable — all interfaces expose only get properties; no setters, no methods that mutate state.
• Composable — IChart is built from IChartType, IAxis, and IEnumerable<IChartSeries>; complex structure is expressed through composition.
• Primitive-typed — string properties use IString from Pure.Primitives.Abstractions, not System.String, keeping the model framework-agnostic.
• AOT-compatible — the library is fully compatible with Native AOT compilation.

Dependencies

• Pure.Primitives.Abstractions — base interfaces for immutable primitive types (IString, INumber<T>, etc.)

Target Frameworks

• .NET 7
• .NET 8
• .NET 9
• .NET 10

Installation

dotnet add package Pure.Chart.Model.Abstractions

Usage

Implement the interfaces to model a chart in your domain:

using Pure.Chart.Model.Abstractions;
using Pure.Primitives.Abstractions.String;

public sealed class BarChartType : IChartType
{
    public IString Name { get; } = new StringValue("Bar");
}

public sealed class SalesChart : IChart
{
    public IString Title { get; } = new StringValue("Monthly Sales");
    public IString Description { get; } = new StringValue("Sales figures by month");
    public IChartType Type { get; } = new BarChartType();
    public IAxis XAxis { get; } = new MonthAxis();
    public IAxis YAxis { get; } = new RevenueAxis();
    public IEnumerable<IChartSeries> Series { get; } = [new SalesSeries()];
}
