+# Simplified Bar Gauges - Clean Single-Color Design
+
+## The Simple Approach
+
+I've created **truly simplified versions** of the vertical and horizontal bar gauges that eliminate ALL alignment issues by using a **single-color approach**.
+
+### 🎯 How It Works
+
+Instead of drawing multiple color bands (green/yellow/red zones), the **entire bar changes color** based on the current value:
+
+- **🟢 Green bar** = Value is in the safe range
+- **🟡 Yellow bar** = Value is in warning range (high or low)
+- **🔴 Red bar** = Value is in alarm range (high or low)
+
+This is like a modern "traffic light" gauge - the whole bar tells you the status at a glance.
+
+### ✅ Benefits
+
+1. **Zero alignment issues** - No color bands to align!
+2. **Cleaner appearance** - Modern, minimalist design
+3. **Easier to read** - Color indicates status instantly
+4. **Simpler code** - No complex segment or threshold calculations
+5. **Better performance** - Fewer drawing operations
+
+## Files Created & Modified
+
+### New Gauge Classes:
+1. **`src/pyefis/instruments/gauges/verticalBarSimple.py`** ✅
+   - Simplified vertical bar with single-color approach
+   - 182 lines, complete implementation
+
+2. **`src/pyefis/instruments/gauges/horizontalBarSimple.py`** ✅
+   - Simplified horizontal bar with single-color approach
+   - 171 lines, complete implementation
+
+### Updated Files:
+3. **`src/pyefis/instruments/gauges/__init__.py`** ✅
+   - Added imports for `HorizontalBarSimple` and `VerticalBarSimple`
+
+4. **`src/pyefis/screens/screenbuilder.py`** ✅
+   - Added support for `vertical_bar_gauge_simple` type
+   - Added support for `horizontal_bar_gauge_simple` type
+
+5. **`config/preferences.yaml.custom`** ✅
+   - All 12 EGT/CHT bars (BAR11-22) configured to use `vertical_bar_gauge_simple`
+
+## Visual Comparison
+
+### Old Multi-Band Approach:
+```
+EGT Bar:
+┌───┐
+│RED│ ← High alarm zone (>650°C)
+├───┤
+│YEL│ ← High warn zone (620-650°C)
+├───┤
+│GRN│ ← Safe zone
+│███│ ← Current value (filled)
+│GRN│
+├───┤
+│YEL│ ← Low warn zone
+├───┤
+│RED│ ← Low alarm zone
+└───┘
+
+Problem: Color bands can misalign between bars
+```
+
+### New Single-Color Approach:
+```
+EGT at 550°C (safe):    EGT at 630°C (warn):    EGT at 660°C (alarm):
+┌───┐                   ┌───┐                   ┌───┐
+│   │                   │   │                   │   │
+│   │                   │   │                   │   │
+│   │                   │YEL│                   │RED│
+│GRN│ ← Filled          │YEL│ ← Filled          │RED│ ← Filled
+│GRN│                   │YEL│                   │RED│
+└───┘                   └───┘                   └───┘
+
+Benefit: Entire bar changes color - no alignment issues!
+```
+
+## Configuration
+
+Your `config/preferences.yaml.custom` is **already configured** with the simple gauges:
+
+```yaml
+gauges:
+  # EGT for cylinders 1-4
+  BAR11:
+    type: vertical_bar_gauge_simple
+  BAR12:
+    type: vertical_bar_gauge_simple
+  BAR13:
+    type: vertical_bar_gauge_simple
+  BAR14:
+    type: vertical_bar_gauge_simple
+
+  # CHT for cylinders 1-4
+  BAR15:
+    type: vertical_bar_gauge_simple
+  BAR16:
+    type: vertical_bar_gauge_simple
+  BAR17:
+    type: vertical_bar_gauge_simple
+  BAR18:
+    type: vertical_bar_gauge_simple
+
+  # EGT for cylinders 5-6
+  BAR19:
+    type: vertical_bar_gauge_simple
+    # ... cylinder 5 settings
+  BAR20:
+    type: vertical_bar_gauge_simple
+    # ... cylinder 6 settings
+
+  # CHT for cylinders 5-6
+  BAR21:
+    type: vertical_bar_gauge_simple
+    # ... cylinder 5 settings
+  BAR22:
+    type: vertical_bar_gauge_simple
+    # ... cylinder 6 settings
+```
+
+## How to Test
+
+**Restart pyEfis to see the new single-color bars:**
+
+```bash
+cd ~/makerplane/pyefis
+python pyEfis.py
+```
+
+## What to Expect
+
+With the simple gauges, you'll see:
+- ✅ **Entire bar is one solid color** - Green, yellow, or red
+- ✅ **Bar fills from bottom to top** showing current value
+- ✅ **Color indicates status** - No need to look at which zone the value is in
+- ✅ **Zero alignment issues** - No color bands to align!
+- ✅ **Clean, modern appearance** - Minimalist design
+- ✅ **All functionality preserved** - Highlights, peak mode, normalize mode still work
+- ✅ **Magenta circles still work** - Highlighting the hottest cylinder (EGTMAX1/CHTMAX1)
+
+### Color Logic:
+The bar color is determined by the **current value** vs thresholds:
+
+1. **🔴 Red (Alarm)**: 
+   - EGT ≥ 650°C (highAlarm) 
+   - CHT ≥ 232°C (highAlarm)
+   - Or values below lowAlarm
+
+2. **🟡 Yellow (Warning)**:
+   - EGT ≥ 620°C (highWarn) but < 650°C
+   - CHT ≥ 204°C (highWarn) but < 232°C
+   - Or values below lowWarn but above lowAlarm
+
+3. **🟢 Green (Safe)**:
+   - All other values (between lowWarn and highWarn)
+
+## Alternative Gauge Options
+
+You have three gauge types available:
+
+### 1. **Simple (Currently Active)** - Recommended ✅
+```yaml
+type: vertical_bar_gauge_simple
+```
+- Entire bar changes color based on value
+- Clean, modern look
+- No alignment issues
+
+### 2. **Improved** - Multi-band with fixed alignment
+```yaml
+type: vertical_bar_gauge_improved
+```
+- Traditional color bands (green/yellow/red zones)
+- Better pixel alignment than original
+- Use if you prefer the traditional multi-band look
+
+### 3. **Original** - Default multi-band
+```yaml
+type: vertical_bar_gauge
+```
+- Original implementation
+- Has the alignment issue you reported
+- Available for comparison
+
+## Technical Implementation
+
+### Simple Gauge Approach
+
+The simple gauge uses a single `_getBarColor()` method that checks the current value against thresholds:
+
+```python
+def _getBarColor(self):
+    """Determine bar color based on current value and thresholds."""
+    value = self._value
+
+    # Check high alarm first (highest priority)
+    if self.highAlarm is not None and value >= self.highAlarm:
+        return self.alarmColor  # Red
+
+    # Check high warning
+    if self.highWarn is not None and value >= self.highWarn:
+        return self.warnColor   # Yellow
+
+    # Check low alarm
+    if self.lowAlarm is not None and value <= self.lowAlarm:
+        return self.alarmColor  # Red
+
+    # Check low warning
+    if self.lowWarn is not None and value <= self.lowWarn:
+        return self.warnColor   # Yellow
+
+    # Default to safe
+    return self.safeColor       # Green
+```
+
+### Drawing Process
+
+1. Draw dark gray background (empty portion)
+2. Calculate value pixel position
+3. Get bar color based on `_getBarColor()`
+4. Draw filled portion from bottom to value position in that color
+5. Draw highlight ball if this is the hottest cylinder
+6. Draw peak line if in peak mode
+
+This approach is:
+- ✅ **Simpler** - One color calculation instead of multiple band calculations
+- ✅ **Faster** - Fewer draw operations
+- ✅ **More reliable** - No pixel rounding or alignment issues
+- ✅ **Easier to understand** - Color = status, instantly readable
+- ✅ **Inherits from original** - All features (normalize, peak, temperature conversion) preserved
+
+## Summary
+
+All files are created and your configuration is ready:
+
+| File | Status | Lines |
+|------|--------|-------|
+| `verticalBarSimple.py` | ✅ Created | 182 |
+| `horizontalBarSimple.py` | ✅ Created | 171 |
+| `gauges/__init__.py` | ✅ Updated | Imports added |
+| `screenbuilder.py` | ✅ Updated | Types registered |
+| `preferences.yaml.custom` | ✅ Updated | All bars configured |
+
+**Ready to run!** Just restart pyEfis and you'll see the new clean single-color bars. 🚀
