Examples¶

For: developers. Each example demonstrates live what the matching Developer Guide section explains — the guide is the narrative, these are the working code.

Live interactive demos. Each opens a standalone page rendered in the browser.

Run these on your own machine. Every example on this page ships in the downloadable examples package — unzip it, start the bundled server, and edit them locally. The library is included, so it works offline with nothing to install.

Some pages cover several related topics; those links point at the relevant section of the page.

Start here¶

• Showcase — the whole library on one page — four real lot scenarios with the summary panel, statistical findings and the Insights charts, over data you can swap for your own — start here if you are deciding whether wafermap fits your problem

Getting started¶

• Your first wafer map — minimal two-call example, no CSV · Guide: Your first wafer map
• Loading CSV data — parse and map real columnar data · Guide: Loading real data from a CSV
• Geometry inference — omit die size and let the library infer it · Guide: Adding die size and wafer geometry
• Partial data and centre anchoring — anchoring the wafer centre for partial coverage, and why sparse data doesn't need it · Guide: Adding die size and wafer geometry
• Warnings the library surfaces — the built-in ⚠ indicator, warning severity, and the onWarning opt-out for hosts with their own notification UI · Guide: Adding die size and wafer geometry
• Bins and yield — named hard bins, pass/fail colours, yield label · Guide: Working with bins
• Bin colours across a full program — a four-wafer lot with 15 hard bins and 32 soft bins — how every bin keeps its colour, two pass grades, and what happens when soft bins outnumber the palette · Guide: How bin colours are assigned
• Metadata / layout mode — generic categorical colouring from die.metadata, coexists with test/bin data · Guide: Metadata / layout plot mode
• Test values — parametric measurements, spec limits, colorbar · Guide: Working with test values
• Retests — multi-touch probe sequences and retest policy · Guide: Retests and enriching dies after build

Interaction and control¶

• Display control — rotation, flip, plot mode, colour scheme · Guide: Controlling the display
• Custom colour schemes — register your own bin/value palette with registerColorScheme · Guide: Custom colour schemes
• Theming — theme the chrome and canvas with --wmap-* custom properties (light, dark, Nord, Solarized, brand green) · Guide: Controlling the display
• Interaction API — hover, click, box-select, controller methods · Guide: Responding to user interaction
• Web Worker — off-main-thread build for large datasets · Guide: Processing large datasets with a Web Worker

Analysis and layout¶

• Insights chart suite — the built-in charts — yield by wafer, bin pareto, ring/quadrant yield, capability, box plots, histograms and test correlation — with no charting library to add · Guide: The Insights tab
• Statistical findings — ring, quadrant, cluster, edge-arc analysis on a single wafer · Guide: Adding statistical findings
• Summary panel — persistent metadata and stats sidebar docked beside the map · Guide: Summary panel
• Lot gallery — card grid of multiple wafers with shared controls and stacked modes · Guide: Building a lot gallery
• Lot-level findings — cross-wafer trend detection with analyzeWaferLot · Guide: Lot-level statistical findings
• Lot-stack spatial analysis — mean/median/stddev maps aggregated across a lot · Guide: Recipes
• Reticle overlays — photolithography field grid and reticle-position findings · Guide: Reticle overlays
• Multi-site parallel testing — site-based analysis across a multi-site prober card
• Real wafer data (WM-811K) — open dataset with 811 000 wafer records · Guide: Adding statistical findings
• Mixed patterns (MixedWM38) — classified failure pattern dataset · Pattern Detection

Compatibility and advanced¶

• wafermap vs Plotly.js — side-by-side render timings and feature comparison · Performance
