Apache ECharts dashboards in 3: 3-D helps — Section 1158: 3-D helps

Dossier 1158 for Apache ECharts dashboards links case “3-D helps” directly to metric 3 (2026). Numbers are optional. If comparison is the job, label the ends only. Keep Apache ECharts dashboards with “3-D helps” and 3 from 3. Keep the grid faint. Data should own the ink.

In reports, ads and assignments it fits ops dashboards, quarterly packs, live KPI walls. Skip it when a single static bar in a PDF would answer the question. This page gathers anatomy, fit, craft, failure modes and work / ads / school recipes for Apache ECharts dashboards. When should I pick Apache ECharts dashboards?

When the story is: ops dashboards, quarterly packs, live KPI walls. When should I avoid Apache ECharts dashboards? Skip it in cases like: a single static bar in a PDF would answer the question. Baidu ECharts became Apache ECharts as a top GitHub visualization project JSON options mapping datasets to Cartesian, polar and graph views

Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure. Yes for lab reports and poster boards if axes, units and a source line are present. Excel or Google Sheets or PowerPoint; export SVG/PDF. Do not rely on hue alone. Label directly and check greyscale.

Keep axis, unit, and year. If “3-D helps” is the axis, the figure is 3 and the year is 3. Keep Apache ECharts dashboards with “3-D helps” and 3 from 3. 32026

Interactive Scenario & Decision Matrix

Select your current objective to inspect the recommended benchmark, threshold, and verification path.

Leave the current chart type. If a guard warning is showing, fix that field before export.

Briefing 11 for Accessible viz aligns condition “Encoding” with reference value 1917 on the ground.

5-Step Execution & Verification Playbook

  1. Paste stays on this device — JSON you paste or restore never uploads. The studio keeps work in browser memory and local storage only.
  2. sanitizeDoc and guards before render — sanitizeDoc bounds the doc, then guardShape, guardChart and plainText run on every load path. Unknown fields drop; bad docs reject instead of drawing raw.
  3. Recent boards are local — The recent list is saved on this browser. Opening or comparing a snapshot still runs sanitizeDoc first; guards are not skipped on restore.
  4. Coworker export never POSTs — A file or string from a teammate is read locally. Nothing is posted to Tool-Lifes or a third-party ingest endpoint.
  5. Compare is a second sanitize pass — Side-by-side compare loads two already-sanitized boards in memory. It is not an upload or server diff; just a second guard pass on both sides.
06

Myth vs. Evidence Fact-Check

Does the studio upload my board, CSV, or pasted JSON?

No. Work stays on this device. Nothing is posted to a server. Every load, paste, restore, undo and redo runs sanitizeDoc, then guardShape, guardChart and plainText.

What does sanitize do to JSON I paste or restore?

sanitizeDoc keeps a bounded name, shape list and chart. Unknown fields are dropped. Each shape passes guardShape; charts pass guardChart; labels pass plainText. Invalid docs are rejected, not rendered raw.

If I compare or load a recent board, does it leave this browser?

No. Recent boards are local. Compare and load still run sanitizeDoc first. guardShape, guardChart and plainText are not skipped on restore.

Can I open a coworker’s export without sending it off-device?

The file never uploads. sanitizeDoc and the guards run before render. That is not a virus scanner — only open files you trust. Studio stays sanitize-safe; the guards are not optional.
