Angular wrapper for Chart.js providing directives for line, bar, pie, radar, polar area, doughnut, bubble, and scatter charts.
ng2-charts is an Angular wrapper library for Chart.js that provides Angular directives to easily create interactive charts. It allows developers to integrate line, bar, pie, radar, and other chart types into Angular applications with minimal configuration. The library simplifies data visualization by leveraging Chart.js's capabilities within Angular's ecosystem.
Angular developers who need to add interactive charts and data visualizations to their web applications. It's particularly useful for those already familiar with Chart.js who want Angular-specific integration.
Developers choose ng2-charts because it provides a seamless Angular-native experience for Chart.js, with directives, services, and event handling that align with Angular best practices. It reduces boilerplate code while maintaining full access to Chart.js features and customization options.

Provides Angular directives and services that align with Angular's data binding and lifecycle hooks, simplifying chart integration. Evidence from README: It offers 'Angular-specific directives and services for seamless integration with Angular's data binding and lifecycle.'
Maintains complete access to Chart.js features and customization options, allowing granular control over chart data, labels, and configurations. README states: 'Allows granular control over chart data, labels, datasets, and options via Chart.js configurations.'
Includes a ThemeService for dynamic color and style overrides to match application themes easily. README provides an example of overriding colors for dark and light themes using this service.
Supports Angular CLI for automatic installation and configuration, reducing setup time. README shows: 'You can install ng2-charts by using the Angular CLI: ng add ng2-charts.'
Requires manual installation and management of Chart.js as a peer dependency, adding an extra step and potential version conflicts. README explicitly notes: 'You will also need to install and include Chart.js library in your application (it is a peer dependency).'
Chart.js can increase bundle size significantly, and while minimal configurations are possible, optimizing requires extra effort. README admits: 'Alternatively, include a minimal configuration to reduce the bundle size, eg: provideCharts({ registerables: [BarController, Legend, Colors] });'
Frequent updates are needed to align with Angular versions, as shown in the compatibility table, leading to potential breaking changes and migration efforts. The table lists different ng2-charts versions for each Angular version, indicating maintenance overhead.
