An Angular directive for integrating Apache ECharts charts and visualizations into Angular applications.
Ngx-echarts is an Angular directive that provides seamless integration for Apache ECharts, a powerful charting and visualization library. It enables Angular developers to easily create interactive, data-driven charts within their applications using a familiar Angular component model, solving the problem of embedding complex visualizations in Angular apps without direct DOM manipulation.
Angular developers (version 2.x and above) who need to incorporate interactive charts and data visualizations into their web applications, particularly those already using or preferring the Apache ECharts library.
Developers choose ngx-echarts because it offers a lightweight, idiomatic Angular wrapper around the full ECharts API, supporting tree-shaking for optimized bundle sizes and providing Angular-specific features like event binding and dynamic updates through directives and inputs.

Exposes the complete ECharts instance for direct method calls like resize() and showLoading(), allowing fine-grained control over chart behavior as documented in the API section.
Uses Angular directives and event bindings, making it familiar for Angular developers with support for all ECharts events through outputs like (chartClick) and (chartInit).
Includes a [merge] input for partial chart updates, optimizing performance by allowing data changes without re-rendering the entire chart, as highlighted in the directive properties.
Supports tree-shaking and custom ECharts builds, enabling developers to include only necessary chart types and components, reducing bundle size as detailed in the custom build section.
Requires manual import of ECharts core and components for tree-shaking, which is verbose and error-prone, with separate instructions for legacy and modern builds adding confusion.
Tightly coupled with Apache ECharts; updates or breaking changes in ECharts may necessitate ngx-echarts version updates, as seen in the lengthy compatibility list for different Angular versions.
Acts as a thin wrapper, so developers must learn both Angular and ECharts APIs, with no simplification of ECharts' complex configuration options, leading to a steeper learning curve.
