Decision Matrix Bases View

This plugin lets you build decision matrices inside Obsidian Bases. A decision matrix combines your raw scores for different options across various criteria with how much each criterion matters to you — giving you an objective framework for making a choice.

Features

• Two views: a scoring table with weighted totals and rankings, and a visual rankings view with a podium and card list
• Click any score to edit it; changes save to the note's frontmatter straight away
• Rows are ranked by weighted average
• An empty cell means you haven't scored it yet; a 0 means you deliberately gave it zero — both count as 0 in the calculation
• Negative weights let you penalize criteria where a higher value is worse (e.g. cost, risk)
• Rank Raws: when criteria are on incompatible scales (e.g. price in dollars vs. quality out of 10), you can convert a column's values to competition ranks before scoring. The ranked position is shown alongside the original value.
• Collapsible row groups
• Score out of 5, 10, or 100 — switchable per view

Installation

Requires Obsidian 1.9.10+ with Bases enabled.

Search for Decision Matrix Bases View in Settings → Community Plugins.

Setup

The fastest way to get started: go to Settings → Decision Matrix and hit Create examples. It drops a ready-to-use folder into your vault — four notes, a base file, and a decision note with weights already configured. Open it and you'll see both views in action.

How it works

The view pulls scores from any notes in your vault. The only requirement is that those notes have numeric properties — those automatically become your scoring criteria.

Naming your properties

Use whatever property names make sense (cost, quality, ease_of_use). If you want to keep them grouped with a shared prefix in your vault (e.g. score_cost, score_quality), set that prefix in Settings and the view strips it from column headers automatically.

Keeping weights between sessions

Weights you set in the view are session-only by default. To make them stick, add weight_<propertyname> properties to the note that contains ![[yourfile.base]] — for example, weight_cost: 3. The view loads those every time it opens, and you can reset to them at any time with the ↺ button.
