Fixed-height Chart.js dashboard tiles need responsive:true, maintainAspectRatio:false, and an explicit CSS height on the canvas wrapper to prevent zero-height collapse and resize thrash.
Stop lagging dashboards. Learn how to use Chart.js decimation plugins to render massive time-series datasets efficiently without losing the visual shape of your data.
Learn how Chart.js’s responsive and maintainAspectRatio options let you make charts that grow with the page or keep a fixed ratio. A step‑by‑step config example shows the exact code, common pitfalls, and performance tips.
Learn how to use the Chart.js Decimation plugin to render massive time-series datasets without crashing the browser, using LTTB to preserve data peaks.
Chart.js plugins share the chart's canvas, data, and render loop. This architecture note covers the mutation boundaries, ordering declarations, and failure modes that keep a v4 plugin from corrupting the chart it runs in.
Chart.js's built-in decimation plugin downsamples huge line datasets to roughly the canvas pixel width. Here's how to enable it, choose between min-max and LTTB, and handle the fidelity trade-off.
A decision guide for Chart.js v4+ responsive resizing: compare maintainAspectRatio modes, container constraints, and high-DPI handling with a validated dashboard implementation pattern.
