Hill Charts for GitHub nga Martin Lutter

Hill Chart for GitHub adds interactive hill charts directly to GitHub issue pages — the same concept Basecamp popularized for visualizing project progress at a glance.

How it works

The left side of the hill represents "figuring things out" — research, uncertainty, and design. The right side represents "making it happen" — execution and known work. You add named points and drag them along the curve to show where each piece of work stands.

• Open any GitHub issue and click the Hill Chart button in the issue toolbar
• Add points for tasks or workstreams
• Drag them along the hill to show progress
• Click "Paste to comment" — the chart is encoded into the comment form, ready to submit

Where data lives

Chart data is stored inside a regular GitHub issue comment. Nothing leaves GitHub — no external servers, no API tokens, no accounts. The data travels with the issue itself, and anyone with the extension installed can see and edit it.

Features

• Drag-and-drop points along the hill curve
• Charts render inline in issue comments for anyone with the extension
• Copy chart data to clipboard for sharing
• Works on any GitHub repository (public or private)
• No data collection — everything stays in your GitHub issues
• Lightweight, runs only on github.com
