Free · ECharts · Editable React source
Line Foundation
A flexible ECharts line base with references, selection events, Canvas, and SVG rendering.
This is the installable component, not a mockup. Width is a preview container setting; theme and colors use your app’s shadcn CSS variables.
Select a mark or an accessible data-table value, or change the range to inspect the callback.

01 / Installation
Your code. Your project.
Use an initialized shadcn/Tailwind React project. The URL installs the component and its shared files recursively. No namespace configuration, platform account, or agent files.
Next.js, Vite & manual setup →npx shadcn@latest add https://beautifulcharts.dev/r/echarts-line-foundation.jsonPackage dependencies: echarts. Shared files are included in Source above. The installed license file covers the free source.
For a manual install, add those packages, copy every listed Source file to its displayed path, and adjust the @/ alias if your project uses a different one.
02 / Component API
Make it yours.
