Dashboards, data uploads & a new What's New feed

Everything on main is now live: the complete visualization and dashboard suite, fully generalized data uploads (CSV, Parquet, JSON, or Ambyte), a new in-app What's New feed powering this public changelog, and the mobile app current at v2.3.0.

Explore your experiments

Everything on main is now live. The headline is data exploration, end to end: the visualization and dashboard suite is complete and data uploads are fully generalized, so you can bring in data, chart it, and present results without ever leaving openJII. A new in-app What's New feed is what powers this changelog, and on mobile the app is current at v2.3.0.

Visualization & dashboards

An experiment dashboard: scatter, bar, line, dot, and lollipop charts on one page.
An experiment dashboard: scatter, bar, line, dot, and lollipop charts on one page.

  • Every chart family: Basic (area, bar, bubble, dot, lollipop, pie), Statistical (histogram, box, violin, density, ridge), and Scientific (heatmap, contour, correlation matrix), plus specialized charts: polar, wind rose, radar, ternary, alluvial, parallel-coordinates, and carpet.

  • Dashboards: compose visualizations into multi-chart layouts that combine charts and narrative on one page.

  • Slice and compare: an operator-aware filter shelf and a per-participant view for classroom experiments.

  • Raw traces, explorable: a direct answer to the Ghana hackathon finding that raw fluorescence carries more signal than pre-computed parameters.

Scientific and specialized charts: heatmap, contour, correlation matrix, parallel-coordinates, and radar.

Generalized data uploads

The redesigned data and metadata import flow.
The redesigned data and metadata import flow.

  • Upload any tabular dataset: the import flow is generalized beyond MultispeQ measurements, so you can bring your own CSV, Parquet, JSON, or Ambyte data and attach it to an experiment.

  • Redesigned import flow: drag-and-drop file selection, on-selection validation, and a clear append-to-table requirement so every upload lands in the right place.

  • Hardened end to end: Parquet, JSON, and Ambyte ingestion unblocked, upload history hardened, and internal plumbing columns hidden from your data.

A new What's New feed

  • In-app What's New: a panel on web and mobile with a per-user unread indicator that stays in sync across your devices.

  • Public changelog: the /releases page you're reading, with a detail page for every note, now including inline images and video.

Reliability, mobile & polish

  • Dashboard rendering: chart sizing, WebGL exhaustion, render-loop, and correctness fixes across the renderer so large dashboards stay responsive.

  • Mobile (v2.3.0): English by default with an in-app language switcher, further crash hardening from PostHog reports, and longer scan timeouts for extended pre-illumination protocols, on top of the branching measurement flows and offline-scan fixes from the late-June cut.

  • Platform polish: a refreshed public site (logo, footer, spacing) plus a sweep of security and dependency updates.
