+# PX360 Command Center - Implementation Guide
+
+## Overview
+
+The PX360 Command Center is a comprehensive, unified dashboard that consolidates all analytics, KPIs, and metrics from across the PX360 system into a single, powerful command center interface. This document provides detailed information about the implementation, features, and usage of the Command Center.
+
+## Features
+
+### 1. Unified KPI Display
+- **Complaints KPIs**: Total complaints, open complaints, overdue complaints, resolved complaints
+- **Actions KPIs**: Total actions, overdue actions
+- **Surveys KPIs**: Average survey score, negative surveys
+- **Trend Indicators**: Visual indicators showing percentage changes vs. previous period
+
+### 2. Interactive Charts (ApexCharts)
+All charts use ApexCharts library for modern, responsive, and interactive visualizations:
+
+- **Complaints Trend**: Line/Area chart showing complaint volume over time
+- **Complaints by Category**: Donut chart showing distribution across categories
+- **Survey Satisfaction Trend**: Line chart showing satisfaction scores over time
+- **Survey Distribution**: Donut chart showing positive/neutral/negative split
+- **Department Performance**: Bar chart ranking departments by performance
+- **Physician Leaderboard**: Bar chart showing top-performing physicians
+
+### 3. Advanced Filtering System
+Users can filter data by:
+- **Date Range**: Preset options (7 days, 30 days, 90 days, this month, last month, quarter, year) or custom range
+- **Hospital**: Filter by specific hospital (role-based access control)
+- **Department**: Filter by specific department
+- **KPI Category**: Filter by category (complaints, surveys, actions, physicians)
+
+### 4. Data Tables
+- **Overdue Complaints Table**: Shows all overdue complaints with quick action links
+- **Physician Leaderboard Table**: Detailed ranking with ratings, survey counts, and sentiment breakdown
+
+### 5. Export Functionality
+- **Excel Export**: Download dashboard data in Excel (.xlsx) format
+- **PDF Export**: Generate professional PDF reports with all KPIs and data
+- Both exports respect current filter settings
+
+## Architecture
+
+### Backend Components
+
+#### 1. UnifiedAnalyticsService (`apps/analytics/services/analytics_service.py`)
+
+A comprehensive service class that handles all data aggregation and KPI calculations.
+
+**Key Methods:**
+```python
+class UnifiedAnalyticsService:
+    @staticmethod
+    def get_all_kpis(user, date_range, hospital_id, department_id, ...)
+        """Returns all KPIs based on filters"""
+        
+    @staticmethod
+    def get_chart_data(user, chart_type, date_range, ...)
+        """Returns chart data for specific chart type"""
+        
+    @staticmethod
+    def get_date_range_filter(date_range, custom_start, custom_end)
+        """Returns (start_date, end_date) tuple"""
+        
+    @staticmethod
+    def get_complaints_trend(user, start_date, end_date, ...)
+        """Returns complaints trend chart data"""
+        
+    @staticmethod
+    def get_complaints_by_category(user, start_date, end_date, ...)
+        """Returns complaints by category chart data"""
+        
+    # ... additional chart data methods
+```
+
+#### 2. ExportService (`apps/analytics/services/export_service.py`)
+
+Handles Excel and PDF export generation.
+
+**Key Methods:**
+```python
+class ExportService:
+    @staticmethod
+    def prepare_dashboard_data(user, kpis, charts, tables)
+        """Prepares data structure for export"""
+        
+    @staticmethod
+    def export_to_excel(data)
+        """Generates Excel file and returns HttpResponse"""
+        
+    @staticmethod
+    def export_to_pdf(data)
+        """Generates PDF file and returns HttpResponse"""
+```
+
+#### 3. UI Views (`apps/analytics/ui_views.py`)
+
+Django views for rendering the dashboard and handling API requests.
+
+**Key Views:**
+```python
+@login_required
+def command_center(request)
+    """Main dashboard view - renders the HTML template"""
+    
+@login_required
+def command_center_api(request)
+    """API endpoint - returns JSON data for dynamic updates"""
+    
+@login_required
+def export_command_center(request, export_format)
+    """Handles Excel and PDF export requests"""
+```
+
+### Frontend Components
+
+#### 1. Command Center Template (`templates/analytics/command_center.html`)
+
+The main dashboard template includes:
+- Filter panel with collapsible form
+- KPI cards with trend indicators
+- Chart containers for ApexCharts
+- Data tables with sorting and actions
+- Loading overlay
+- JavaScript for dynamic updates
+
+#### 2. JavaScript Functionality
+
+**Key JavaScript Functions:**
+```javascript
+// Global state
+let charts = {};
+let currentFilters = { ... };
+
+// Core functions
+loadDashboardData()              // Loads all dashboard data via AJAX
+updateKPIs(kpis)                 // Updates KPI cards
+updateCharts(chartData)          // Renders/updates ApexCharts
+renderChart(elementId, chartData, chartType)  // Renders individual chart
+updateTables(tableData)          // Updates data tables
+
+// Filter functions
+handleDateRangeChange()          // Shows/hides custom date range
+updateFilters()                  // Updates currentFilters object
+resetFilters()                   // Resets all filters to defaults
+
+// Export functions
+exportDashboard(format)          // Initiates Excel/PDF export
+```
+
+## URL Structure
+
+```
+/analytics/command-center/                    # Main dashboard
+/analytics/api/command-center/                # API endpoint for data
+/analytics/api/command-center/export/excel/   # Excel export
+/analytics/api/command-center/export/pdf/     # PDF export
+```
+
+## Data Flow
+
+### 1. Initial Page Load
+```
+User Request → command_center view
+    ↓
+Render template with initial filters and KPIs
+    ↓
+Return HTML to browser
+    ↓
+JavaScript loads data via AJAX
+    ↓
+command_center_api returns JSON
+    ↓
+Dashboard updates with data
+```
+
+### 2. Filter Change
+```
+User applies filter
+    ↓
+JavaScript updates currentFilters
+    ↓
+loadDashboardData() called
+    ↓
+AJAX request to command_center_api with filters
+    ↓
+Backend aggregates data based on filters
+    ↓
+JSON response with kpis, charts, tables
+    ↓
+JavaScript updates UI components
+```
+
+### 3. Export Request
+```
+User clicks Export → Excel/PDF
+    ↓
+exportDashboard(format) called
+    ↓
+AJAX request to export_command_center
+    ↓
+ExportService generates file
+    ↓
+Browser downloads file
+```
+
+## Role-Based Access Control
+
+The Command Center respects user roles:
+
+### PX Admin
+- Can view data across all hospitals
+- Can filter by any hospital or department
+- Full access to all KPIs and charts
+
+### Hospital Manager
+- Can only view data for their hospital
+- Hospital filter pre-selected to their hospital
+- Can filter by departments within their hospital
+
+### Department Manager
+- Can only view data for their department
+- Hospital and department filters pre-selected
+- Limited to department-specific KPIs
+
+## Chart Configurations
+
+### 1. Line Charts (Trend Data)
+```javascript
+{
+    chart: { type: 'line', height: 350, toolbar: { show: true } },
+    stroke: { curve: 'smooth', width: 3 },
+    fill: { type: 'gradient', gradient: { ... } },
+    xaxis: { categories: [...] },
+    yaxis: { min: 0, forceNiceScale: true }
+}
+```
+
+### 2. Donut Charts (Distribution Data)
+```javascript
+{
+    chart: { type: 'donut', height: 350 },
+    labels: [...],
+    dataLabels: { enabled: true },
+    legend: { position: 'bottom' }
+}
+```
+
+### 3. Bar Charts (Ranking Data)
+```javascript
+{
+    chart: { type: 'bar', height: 350 },
+    plotOptions: { bar: { horizontal: true } },
+    xaxis: { categories: [...] }
+}
+```
+
+## Export Formats
+
+### Excel Export (.xlsx)
+- Contains separate sheets for:
+  - Executive Summary (KPIs)
+  - Detailed Charts Data
+  - Overdue Complaints List
+  - Physician Leaderboard
+- Formatted with proper headers and styling
+- Includes timestamp and filter information
+
+### PDF Export (.pdf)

+
+## Performance Optimizations
+
+1. **Database Query Optimization**
+   - Uses select_related() and prefetch_related() for efficient queries
+   - Aggregates data at database level where possible
+   - Limits result sets for tables (20-100 rows)
+
+2. **Caching**
+   - Consider adding Redis caching for frequently accessed data
+   - Cache chart data for common filter combinations
+
+3. **AJAX Loading**
+   - Initial page load shows skeleton with filters
+   - Data loads asynchronously via AJAX
+   - Prevents page timeout on large datasets
+
+4. **Pagination**
+   - Table results are paginated
+   - Chart data limits to top N items (e.g., top 10 departments)

+
+## Customization Guide
+
+### Adding a New KPI
+
+1. **Add KPI calculation in UnifiedAnalyticsService:**
+```python
+@staticmethod
+def get_all_kpis(user, date_range, ...):
+    kpis = {
+        # existing KPIs
+        'new_kpi': self._calculate_new_kpi(user, date_range, ...),
+    }
+    return kpis
+```
+
+2. **Add KPI card to template:**
+```html
+<div class="col-md-3">
+    <div class="card kpi-card">
+        <div class="card-body">
+            <div class="text-xs font-weight-bold text-primary text-uppercase mb-1">
+                {% trans "New KPI" %}
+            </div>
+            <div class="kpi-value text-primary" id="newKpi">0</div>
+        </div>
+    </div>
+</div>
+```
+
+3. **Update JavaScript:**
+```javascript
+function updateKPIs(kpis) {
+    // existing updates
+    document.getElementById('newKpi').textContent = kpis.new_kpi || 0;
+}
+```
+
+### Adding a New Chart
+
+1. **Add chart data method in UnifiedAnalyticsService:**
+```python
+@staticmethod
+def get_new_chart(user, start_date, end_date, hospital_id, department_id):
+    # Query and aggregate data
+    return {
+        'series': [...],
+        'labels': [...],
+        'chart_type': 'bar',  # or 'line', 'donut', etc.
+        'metadata': {...}
+    }
+```
+
+2. **Add chart method call:**
+```python
+charts = {}
+for chart_type in chart_types + ['new_chart']:
+    charts[chart_type] = UnifiedAnalyticsService.get_chart_data(
+        user=user, chart_type=chart_type, ...
+    )
+```
+
+3. **Add chart container to template:**
+```html
+<div class="col-lg-6">
+    <div class="card">
+        <div class="card-header">
+            <h6 class="m-0 font-weight-bold">{% trans "New Chart" %}</h6>
+        </div>
+        <div class="card-body">
+            <div class="chart-container" id="newChart"></div>
+        </div>
+    </div>
+</div>
+```
+
+## Troubleshooting
