+# Plotting Module
+
+This module provides plotting utilities for visualizing coastal environmental conditions.
+
+## Conditions Plot
+
+The `conditions_plot` function creates a comprehensive visualization of environmental conditions during surveys or operations. It's inspired by operational analysis needs for autonomous surface vehicles and field campaigns.
+
+### Features
+
+- **Flexible variable selection**: Plot any combination of variables (default: wave height vs. peak period)
+- **Multiple survey groups**: Support for multiple groups with different colors and markers
+- **Climatological context**: Background distributions show typical conditions
+- **Color coding**: Optional color coding by scalar values
+- **Date flexibility**: Accept both datetime objects and date strings
+- **Customizable styling**: Control axis limits, bin sizes, markers, and more
+
+### Basic Usage
+
+```python
+import datetime as dt
+from murgtools.plotting import conditions_plot
+
+# Define survey dates
+dates = [
+    dt.datetime(2023, 6, 15),
+    dt.datetime(2023, 7, 20)
+]
+
+# Define time range for background climatology
+start = dt.datetime(2023, 1, 1)
+end = dt.datetime(2023, 12, 31)
+
+# Create the plot
+fig, axes = conditions_plot(dates, start, end, ofname='survey_conditions.png')
+```
+
+### Advanced Usage
+
+#### Multiple Survey Groups
+
+```python
+date_groups = [
+    {
+        'dates': [dt.datetime(2023, 6, 15), dt.datetime(2023, 6, 20)],
+        'label': 'Survey A',
+        'color': '#ff7f0e',
+        'marker': 'D'
+    },
+    {
+        'dates': [dt.datetime(2023, 7, 10)],
+        'label': 'Survey B',
+        'color': '#1f77b4',
+        'marker': 'o'
+    }
+]
+
+all_dates = [dt.datetime(2023, 6, 15), dt.datetime(2023, 6, 20), 
+             dt.datetime(2023, 7, 10)]
+
+fig, axes = conditions_plot(
+    all_dates, start, end,
+    date_groups=date_groups,
+    sampling_hours=2,
+    start_hour=13,
+    ofname='multi_group_conditions.png'
+)
+```
+
+#### Custom Variables
+
+```python
+# Plot peak period vs wave height
+fig, axes = conditions_plot(
+    dates, start, end,
+    x_var='Tp',
+    y_var='Hs',
+    x_limits=[5, 20],
+    y_limits=[0, 3],
+    ofname='custom_vars.png'
+)
+```
+
+#### Color by Scalar Value
+
+```python
+# Color points by wave direction
+fig, axes = conditions_plot(
+    dates, start, end,
+    color_var='waveDirectionPeak',
+    ofname='colored_by_direction.png'
+)

+# Feature Enhancement: Support continuous time sampling for ASV operations
+
+## Summary
+Add support for continuous time range sampling in `conditions_plot()` to better represent extended autonomous surface vehicle (ASV) or boat operations, instead of sampling only discrete hourly intervals.
+
+## Current Behavior
+The `conditions_plot()` function currently samples data at discrete hourly intervals:
+- `time_list`: List of dates when surveys occurred
+- `sampling_hours`: Number of consecutive hours to sample (default: 1)  
+- `start_hour`: Starting hour in UTC for sampling (default: 13)
+
+**Example**: For date 2023-06-15 with `sampling_hours=2` and `start_hour=13`, only data at 13:00 and 14:00 UTC are plotted.
+
+## Problem
+For ASV operations or surveys that span multiple hours or entire days with varying start/end times, the current approach:
+- Doesn't capture all data points during actual operation periods
+- Assumes fixed start times across all survey dates
+- Loses information about conditions experienced during extended operations
+
+## Proposed Solutions
+
+### Option 1: Time Range Support in date_groups (Recommended)
+
+Add support for tuples of (start_time, end_time) in the `dates` field:
+
+```python
+from datetime import datetime
+from murgtools import conditions_plot
+
+date_groups = [
+    {
+        'dates': [
+            (datetime(2023, 6, 15, 12, 0), datetime(2023, 6, 15, 18, 30)),  # 6.5 hours
+            (datetime(2023, 6, 20, 10, 15), datetime(2023, 6, 20, 16, 45))  # 6.5 hours
+        ],
+        'label': 'ASV Survey',
+        'color': '#ff7f0e',
+        'marker': 'D'
+    }
+]
+
+fig, axes = conditions_plot(
+    time_list=None,  # Not needed when using date_groups with ranges
+    start_date=datetime(2023, 1, 1),
+    end_date=datetime(2023, 12, 31),
+    date_groups=date_groups
+)
+```
+
+**Pros**:
+- Integrates naturally with existing date_groups structure
+- Maintains backward compatibility (single datetime still works)
+- Each group can have different time ranges
+
+**Cons**:
+- Requires checking if date is datetime or tuple in processing logic
+
+### Option 2: Separate time_ranges Parameter
+
+Add a new `time_ranges` parameter alongside `time_list`:
+
+```python
+time_ranges = [
+    (datetime(2023, 6, 15, 12, 0), datetime(2023, 6, 15, 18, 30)),
+    (datetime(2023, 6, 20, 10, 0), datetime(2023, 6, 20, 16, 45))
+]
+
+fig, axes = conditions_plot(
+    time_list=None,
+    time_ranges=time_ranges,
+    start_date=datetime(2023, 1, 1),
+    end_date=datetime(2023, 12, 31)
+)
+```
+
+**Pros**:
+- Clear separation between discrete times and time ranges
+- Easy to validate inputs
+
+**Cons**:
+- Adds another parameter to function signature
+- Can't mix ranges and discrete times easily
+- Doesn't work well with date_groups styling
+
+### Option 3: Smart Auto-Detection
+
+Automatically detect tuples in `time_list` and treat them as time ranges:
+
+```python
+time_list = [
+    (datetime(2023, 6, 15, 12, 0), datetime(2023, 6, 15, 18, 30)),  # Time range
+    datetime(2023, 7, 20),  # Single point (uses sampling_hours/start_hour)
+    (datetime(2023, 8, 10, 9, 0), datetime(2023, 8, 10, 15, 30))   # Time range
+]
+
+fig, axes = conditions_plot(
+    time_list=time_list,
+    start_date=datetime(2023, 1, 1),
+    end_date=datetime(2023, 12, 31),
+    sampling_hours=2,  # Used for single datetime entries
+    start_hour=13
+)
+```
+
+**Pros**:
+- Most flexible - can mix single points and ranges
+- No new parameters needed
+- Intuitive API
+
+**Cons**:
+- Less explicit - behavior depends on input type
+- May be confusing for users expecting consistent behavior
+
+## Implementation Details
+
+For any option, the implementation would:
+
+1. Detect if a date entry is a time range (tuple) or single point (datetime)
+2. For time ranges: Extract all data points between start and end times
+3. For single points: Use existing `sampling_hours` and `start_hour` logic
+4. Plot all collected points with the same styling
+
+**Code location**: `murgtools/plotting/conditions_plot.py` lines 295-306 (current time sampling logic)
+
+## Benefits
+
+- **Better representation**: Shows actual conditions during entire operation
+- **More accurate**: Captures temporal variability within operations
+- **Flexible**: Supports both discrete sampling and continuous operations
+- **Backward compatible**: Existing code continues to work (if implemented carefully)
+
+## Priority
+
+**Medium** - Valuable enhancement that improves usefulness for ASV/extended operations without breaking existing functionality.
+
+## Related Files
+
+- `murgtools/plotting/conditions_plot.py` - Main implementation
+- `tests/test_conditions_plot.py` - Add tests for new functionality
+- `examples/example_conditions_plot.py` - Add example demonstrating time ranges
+- `murgtools/plotting/README.md` - Document new capability
+
+## Acceptance Criteria
+
+- [ ] Time ranges can be specified for survey dates
+- [ ] All data points within time ranges are plotted
+- [ ] Backward compatibility maintained for existing code
+- [ ] Unit tests cover new functionality
+- [ ] Documentation updated with examples
+- [ ] Works correctly with date_groups styling

-    datetime(2023, 7, 20),  # Single point (uses sampling_hours/start_hour)
-    (datetime(2023, 8, 10, 9, 0), datetime(2023, 8, 10, 15, 30))   # Time range

-fig, axes = conditions_plot(
-    time_list=time_list,
-    start_date=datetime(2023, 1, 1),
-    end_date=datetime(2023, 12, 31),
-    sampling_hours=2,  # Used for single datetime entries
-    start_hour=13
-)
-```
-
-**Pros**:
-- Most flexible - can mix single points and ranges
-- No new parameters needed
-- Intuitive API
-
-**Cons**:
-- Less explicit - behavior depends on input type
-- May be confusing for users expecting consistent behavior
-
-## Implementation Details
-
-For any option, the implementation would:
-
-1. Detect if a date entry is a time range (tuple) or single point (datetime)
-2. For time ranges: Extract all data points between start and end times
-3. For single points: Use existing `sampling_hours` and `start_hour` logic
-4. Plot all collected points with the same styling
-
-**Code location**: `murgtools/plotting/conditions_plot.py` lines 295-306 (current time sampling logic)
-
-## Benefits
-
-- **Better representation**: Shows actual conditions during entire operation
-- **More accurate**: Captures temporal variability within operations
-- **Flexible**: Supports both discrete sampling and continuous operations
-- **Backward compatible**: Existing code continues to work (if implemented carefully)
-
-## Priority
-
-**Medium** - Valuable enhancement that improves usefulness for ASV/extended operations without breaking existing functionality.
-
-## Related Files
-
-- `murgtools/plotting/conditions_plot.py` - Main implementation
-- `tests/test_conditions_plot.py` - Add tests for new functionality
-- `examples/example_conditions_plot.py` - Add example demonstrating time ranges
-- `murgtools/plotting/README.md` - Document new capability
-
-## Acceptance Criteria
-
-- [ ] Time ranges can be specified for survey dates
-- [ ] All data points within time ranges are plotted
-- [ ] Backward compatibility maintained for existing code
-- [ ] Unit tests cover new functionality
-- [ ] Documentation updated with examples
-- [ ] Works correctly with date_groups styling

Subject: [PATCH 16/17] Fix test compatibility for Python 3.9/3.10

The tests were failing on Python 3.9 and 3.10 due to a naming collision:
the module `conditions_plot.py` exports a function also named
`conditions_plot`, causing mock.patch to find the function instead of
the module when resolving the patch path.

Fix by using sys.modules to get the actual module object for patching,
and add real test implementations for bin_data tests.
