SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables developers to render Chart.js visualizations within a Helios-powered timeline, providing deterministic frame updates by bypassing Chart.js internal animations.

Core Features & Use Cases

  • Chart.js + Helios integration: drive chart data from the Helios timeline and disable built-in transitions.
  • Deterministic rendering: update datasets synchronously in a timeline-driven loop for consistent frame output.
  • Use Case: Build a live dashboard that updates bar chart data every few frames without chart animation, ensuring smooth frame pacing.

Quick Start

Bind Helios to the document timeline and configure Chart.js to disable animations; update chart data in the Helios subscription using chart.update('none').

FAQPage Schema
How do I disable Chart.js animations for deterministic frame updates in a web dashboard?

To disable Chart.js animations for deterministic frame updates, configure the chart to bypass transitions and update datasets synchronously using chart.update('none') within a timeline-driven loop. This ensures consistent frame output for live dashboards.

What is the best way to drive Chart.js data visualizations from a timeline?

The best way to drive Chart.js data visualizations from a timeline is to integrate it with Helios. This binds chart data updates to the document timeline, disabling built-in transitions to provide deterministic rendering for web dashboards.

Can I use Chart.js with Helios to build a live dashboard with smooth frame pacing?

Yes, you can use Chart.js with Helios to build a live dashboard with smooth frame pacing. By binding Helios to the document timeline and disabling Chart.js animations, datasets update synchronously without visual frame dropping.

Do I need Chart.js version 3 or higher to avoid built-in transitions during timeline updates?

Yes, you need Chart.js version 3 or higher along with Helios core to avoid built-in transitions during timeline updates. This configuration allows you to perform synchronous data updates via chart.update('none').

Why does my Chart.js animation conflict with deterministic rendering loops?

Chart.js animation conflicts with deterministic rendering loops because built-in transitions operate asynchronously. To resolve this, disable animations and use chart.update('none') within a Helios subscription for synchronous, timeline-driven frame output.

How do I configure Chart.js to update bar chart data every few frames without animation?

To update bar chart data every few frames without animation, bind Helios to the document timeline and configure Chart.js to disable animations. Update the datasets synchronously inside the Helios subscription using chart.update('none').
