AG Charts Server-Side Rendering Examples

Open in GitHub Codespaces

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
01-basic-render.ts npm run basic Renders a bar chart to PNG
02-jpeg-output.ts npm run jpeg JPEG output with quality and high-DPI settings
03-express-server.ts npm run server HTTP endpoint serving chart images at localhost:3000/chart.png

Codespaces

Click the badge above to launch a ready-to-use environment. Once open:

npm run server

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

Requirements

  • Node.js 20.0.0 or later
  • skia-canvas native dependencies (included in the Codespaces image)
