Apache ECharts

Project67.5K

Build interactive, customizable charts for browser applications.

Added 2026-10-07
Replaces

What you can build

  • Parse uploaded rows, validate required fields and dates, then output normalized chart-ready records and a separate report of rejected rows.
  • Join actual and target records by period, calculate absolute and percentage variance, and output matched series plus unmatched-period records.
  • Apply a user-maintained alias map before aggregation, then output grouped totals and a separate list of labels without mappings.
  • Compute a configurable rolling average from ordered numeric readings, then output original and smoothed series for visual comparison.
  • Find transitions across a chosen threshold in timestamped readings, then output event timestamps and values alongside the chart data.

Try this prompt

Build a small browser workflow that accepts timestamped sensor readings and a user-selected threshold. Preserve the original input, validate records, identify threshold crossings, and display the readings with crossings visually distinguished using Apache ECharts. Show a separate event list with timestamps and values, plus clear errors for rejected records. Document the accepted input format and threshold rule; do not overwrite source data.

Get started

  1. Choose how to obtain ECharts

    The README documents obtaining ECharts from the official website, installing it through npm, or loading it from a CDN.

  2. Follow the integration documentation

    Use the linked Get Started handbook for browser integration, then consult the API and option manual for chart configuration.

  3. Prepare for source development

    Building from source requires Node.js. The README documents dependency installation, development watch mode, TypeScript checks, and production builds.

License & notes

Apache-2.0Apache License 2.0 permits commercial use subject to its terms. When distributing copies or derivatives, retain required notices and attribution and mark modified files. The license file notes specified embedded d3.js files have BSD 3-Clause terms. The README documents npm, official-site download, and CDN options, but gives no prices. Hosting and any data services you add may have separate costs; no paid API or model cost is documented.

  • ECharts provides visualization, not turnkey data ingestion, validation, storage, hosting, or analytics; add those capabilities in your application.
  • The README links to API and chart-option documentation but does not detail chart-specific behavior; verify needed details in those references.
  • Apache License 2.0 redistribution requires applicable notices and attribution; the license file separately identifies specified embedded d3.js files under BSD 3-Clause terms.
