AG Charts Server-Side Rendering Examples

Render AG Charts to PNG and JPEG images in Node.js, without a browser. See the documentation for full details.

Quick Start

npm install
npm run basic

The rendered chart is written to output/chart.png.

Examples

Script	Command	Description

Codespaces auto-forwards port 3000 and provides a URL to view the chart in your browser.
