# ✅ Refactoring Complete - Clean Code with ApexCharts

## 🎯 What Was Changed

Following your feedback, I've refactored all inline CSS and JavaScript to use proper classes and the existing ApexCharts library.

---

## ✅ **Changes Made**

### **1. Removed All Inline Styles (`resources/views/reports/leaves-report.blade.php`)**

**Before:**
```blade
<div style="margin-bottom: 2rem; background: white; padding: 1rem; border-radius: 8px;">
    <canvas style="max-height: 300px; display: block;"></canvas>
</div>
```

**After:**
```blade
<div class="leave-chart-container leave-chart-container-pie">
    <div id="paidVsUnpaidChart"></div>
</div>
```

### **2. Removed Chart.js Library**
- Removed: `<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>`
- Using: Existing ApexCharts library from layout (already included)

### **3. Added Custom CSS Classes (`public/assets/css/custom.css`)**

Added proper CSS classes to `custom.css`:
```css
.leave-chart-container {
    margin-bottom: 2rem;
    background: white;
    padding: 1rem;
    border-radius: 0.375rem;
}

.leave-chart-container canvas {
    display: block;
}

.leave-chart-container-pie {
    max-height: 350px;
}

.leave-chart-container-bar {
    max-height: 400px;
}

.leave-chart-container-line {
    max-height: 300px;
}
```

### **4. Refactored JavaScript (`public/assets/js/pages/leaves-report.js`)**

**Before:** Chart.js implementation with inline styles
```javascript
const parent = ctx1.parentElement;
parent.style.height = '350px';
parent.style.width = '100%';

paidVsUnpaidChart = new Chart(ctx1, {
    type: 'pie',
    // ... Chart.js options
});
```

**After:** ApexCharts implementation
```javascript
const pieChartOptions = {
    chart: {
        type: 'pie',
        height: 300
    },
    series: [paidDays, unpaidDays],
    labels: ['Paid Leaves', 'Unpaid Leaves'],
    colors: ['#71dd37', '#ffab00'],
    // ... ApexCharts options
};

paidVsUnpaidChart = new ApexCharts(document.querySelector("#paidVsUnpaidChart"), pieChartOptions);
paidVsUnpaidChart.render();
```

## 📊 **Charts Implementation**

### **Chart 1: Paid vs Unpaid Pie Chart**
- Uses ApexCharts pie chart
- Colors: Green (#71dd37) for paid, Orange (#ffab00) for unpaid
- Legend at bottom

### **Chart 2: Utilization Bar Chart**
- Uses ApexCharts bar chart
- Color-coded by utilization level
- Rotated labels for better readability
- Top 10 users only

### **Chart 3: Trend Line Chart**
- Uses ApexCharts line chart
- Smooth curve
- Placeholder for future enhancement

---

## 🎨 **Classes Used**

### **Bootstrap/Sneat Classes:**
- `modal` / `modal-dialog` / `modal-xl`
- `modal-header` / `modal-body`
- `modal-title` / `modal-content`
- `btn-close` / `btn-info` / `btn-primary`

### **Custom Classes:**
- `.leave-chart-container` - Base container
- `.leave-chart-container-pie` - Pie chart specific
- `.leave-chart-container-bar` - Bar chart specific
- `.leave-chart-container-line` - Line chart specific

---

## ✅ **Benefits**

1. **Clean Code**: No inline styles/scripts
2. **Maintainable**: Styles in CSS file, easy to update
3. **Consistent**: Uses existing library (ApexCharts)
4. **Professional**: Follows best practices
5. **Reusable**: Classes can be used elsewhere
6. **Smaller Bundle**: No duplicate chart library
