example-chartjs SKILL.md skillA
example-chartjs from bintzgavin/helios is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bintzgavin/helios/example-chartjs@git:20261009.c6b0c13Pins git:20261009.c6b0c13 in mdr.lock. Pin the fingerprint instead.

Chart.js integration patterns for Helios. Use when creating animated data visualizations with Chart.js.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chart.js + Helios
Integrate Helios with Chart.js by disabling internal animations and manually driving data updates from the timeline.
## Quick Start
```typescript
import { Helios } from '@helios-project/core';
import Chart from 'chart.js/auto';
const helios = new Helios({ fps: 30, duration: 5 });
helios.bindToDocumentTimeline();
const ctx = document.getElementById('chart').getContext('2d');
const chart = new Chart(ctx, {
type: 'bar',
data: { /* ... */ },
options: {
// CRITICAL: Disable internal tweens
animation: false,
responsive: true
}
});
helios.subscribe((state) => {
const t = state.currentTime;
// 1. Calculate new data based on time
const newData = calculateData(t);
// 2. Update chart data
chart.data.datasets[0].data = newData;
// 3. Force immediate update without animation
chart.update('none');
});
```
## Key Patterns
### Disable Animations
Chart.js has a built-in animation engine that tweens values when data changes. This conflicts with frame-by-frame rendering. You must disable it:
```javascript
options: {
animation: false
}
```
### Immediate Updates

How to install
mdr add bintzgavin/helios/example-chartjs@sha256:5f7b1fb1ed7de58fThe line at the top of this page pins the label git:20261009.c6b0c13, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
