  • Query success rate

Advanced Analytics

• Page reference frequency analysis
  • Which pages are cited most
  • Identify underutilized documents
  • Generate recommendations
• Query complexity metrics
  • Average query length
  • Common query patterns
  • Frequently used keywords

  • Export to CSV
  • Export to JSON
  • Export charts as images (PNG)
  • Generate PDF report
  • Include date range in filename
  • Progress indicator for large exports

Acceptance Criteria

• Dashboard displays all analytics charts correctly
• Charts are interactive (hover, click, zoom)
• Data accurately reflects actual query history
• Can filter analytics by date range (last 7/30/90 days, all time)
• Can filter by specific documents
• Statistics cards show accurate metrics with trends
• Dashboard loads efficiently even with large datasets (1000+ queries)
• Charts are responsive and work on mobile
• Can export data to CSV and JSON
• All charts have proper legends and labels
• Color scheme matches application theme
• Tooltips provide detailed information
• No performance degradation with analytics running

Dependencies

• All previous versions (v0.1.0 - v0.4.0)
• Document from src/store/types.ts
• QuerySource from src/store/types.ts
• Existing query and message data
• New chart.js and vue-chartjs libraries

Design Notes

Layout

• 4-column grid on desktop, 1-column on mobile
• Summary cards at top
• Large charts in middle section
• Detailed tables at bottom

Colors (Chart.js compatible)

• Primary: #3B82F6 (blue)
• Success: #22C55E (green)
• Warning: #EAB308 (yellow)
• Danger: #EF4444 (red)
• Neutral: #6B7280 (gray)

Chart Options

• Enable animations (300ms duration)
• Responsive: true
• MaintainAspectRatio: false
• Show legend for multi-series charts
• Grid lines: subtle gray
• Font family: match app theme

Technical Considerations

Performance

• Aggregate data client-side for <10,000 queries
• Consider backend aggregation for larger datasets
• Cache computed analytics for 5 minutes
• Use Web Workers for heavy calculations
• Lazy load charts (only render when in viewport)

Data Storage

• Store raw analytics data in IndexedDB if exceeds localStorage limit
• Keep last 365 days of detailed data
• Aggregate older data into monthly summaries
• Implement data cleanup strategy

Chart Configuration

// Example configuration
{
  responsive: true,
  maintainAspectRatio: false,
  plugins: {
    legend: { display: true, position: 'bottom' },
    tooltip: { mode: 'index', intersect: false }
  },
  scales: {
    y: { beginAtZero: true }
  }
}

Testing Checklist

• Test with no query history
• Test with small dataset (<10 queries)
• Test with large dataset (1000+ queries)
• Test date range filtering
• Test document filtering
• Test export to CSV
• Test export to JSON
• Test chart interactivity (hover, click)
• Test responsive behavior on mobile
• Test with different time zones
• Test chart rendering performance
• Test with incomplete data (missing fields)
• Verify calculation accuracy of all metrics

Related Issues

• Depends on: All previous versions (v0.1.0 - v0.4.0)
• Related to: Future v0.6.0 (suggestions can use analytics data)
