Quadrant Charts

Quadrant charts divide a space into four sections based on two axes. They are perfect for priority matrices, risk assessments, and strategic analysis frameworks like the Eisenhower Matrix.

Basic Example

quadrantChart
    title Priority Matrix
    x-axis Low Effort --> High Effort
    y-axis Low Impact --> High Impact
    quadrant-1 Do First
    quadrant-2 Schedule
    quadrant-3 Delegate
    quadrant-4 Eliminate

    Quick Fix: [0.2, 0.8]
    Major Feature: [0.8, 0.9]
    Minor Tweak: [0.3, 0.2]
    Complex Legacy: [0.9, 0.3]

What You Get

Quick Syntax Reference

Chart Structure

quadrantChart
    title Chart Title
    x-axis Left Label --> Right Label
    y-axis Bottom Label --> Top Label
    quadrant-1 Top Right Name
    quadrant-2 Top Left Name
    quadrant-3 Bottom Left Name
    quadrant-4 Bottom Right Name

Plotting Points

Points are defined with a name and coordinates:

Point Name: [x, y]

Coordinates range from 0 to 1:

• [0, 0] is bottom-left
• [1, 1] is top-right
• [0.5, 0.5] is center

Common Use Cases

• Priority Matrix: Effort vs Impact
• Risk Assessment: Likelihood vs Severity
• Feature Planning: Value vs Complexity
• Skill Mapping: Competence vs Interest
