node-red-contrib-chartjs

A Node-RED node that provides Chart.js-based charts for Node-RED dashboards. Version 0.5.2 supports line, multi-line, vertical/horizontal bar, pie, doughnut, polar area, bubble, and radar charts. Charts are served on configurable HTTP paths and can be updated at runtime via msg.payload. Uses socket.io and serve-static on the server side. This package is a Node-RED community contribution, not actively maintained with regular releases. Key differentiator: it enables dynamic chart creation and updates within Node-RED flows without custom code.
