Original prompt

This section details on the original issue you should resolve

<issue_title>conditions plot</issue_title>
<issue_description>Create a plot like the one listed in the repo below. make it flexible so i can pass different variables. The default should be wave height and peak period as included in the existing implementation. Additionally, it should have flexibility to color by a scalar value as an option.

it uses a lot of the dependencies that are in this repository already (get data). arguments to be passed should be list of times data are collected.

https://github.com/kkoetje/asv_conditions_plot/blob/main/find_asv_survey_conditions.py
</issue_description>

<agent_instructions>this should probably live in its own directory as helper functions as this creates a whole new category of capability to be provided through this library. it should live next to get data and utils

Pull request overview

This PR adds a new plotting module to visualize environmental conditions during surveys or operations, based on operational needs from the ASV conditions plotting work. The implementation provides a flexible two-panel plot showing time series and scatter distributions with climatological context.

Changes:

New plotting module with conditions_plot() and bin_data() functions
Support for flexible variable selection (default: wave height vs peak period)
Multiple survey groups with customizable styling (colors, markers, labels)

Why is this test commented out?

Fixed in commit 838caed. Refactored the entire example file to use clean, importable functions instead of commented-out code. The examples are now properly structured and can be run individually.

+# Example 6: Color by scalar value (if available in data)
+print("\nExample 6: Color by scalar value")


Most of these examples are commented out. I don't think it's good practice to do this right?

Fixed in commit 838caed. Removed all commented code and restructured as individual example functions that can be imported and run. Much cleaner approach.

+    else:
+        # Process dates in each group
+        for group in date_groups:
+            processed_dates = []
+            for d in group['dates']:
+                if isinstance(d, str):
+                    processed_dates.append(dt.datetime.strptime(d, '%Y%m%d'))
+                elif isinstance(d, dt.datetime):
+                    processed_dates.append(d)
+                else:
+                    raise ValueError(f"Unsupported date format: {type(d)}")
+            group['dates'] = processed_dates
+            # Set default marker if not provided
+            if 'marker' not in group:
+                group['marker'] = 'o'


When date_groups is provided, the code doesn't validate that each group dictionary contains the required keys ('dates', 'label', 'color'). Missing keys will cause KeyError exceptions later (e.g., at lines 225, 227). Consider adding validation after line 196 to check for required keys and provide helpful error messages if they're missing.

implement as a function

Implemented in commit 70ae4fd. Added _validate_date_groups() function that checks for required keys ('dates', 'label', 'color') and validates that 'dates' is a list. The function provides clear error messages indicating which keys are missing.

+                     np.ceil(np.nanmax(data_to_be_binned)) + bin_size, 
+                     bin_size)
+    # np.digitize returns 1-based indices, convert to 0-based for Python consistency
+    bin_indices = np.digitize(data_to_be_binned, bins=bins, right=False) - 1


The bin_data function has a potential bug with values exactly equal to np.nanmin(data_to_be_binned). Since bins start at np.nanmin(data_to_be_binned), the minimum value in the data will fall exactly on the first bin edge. With right=False in np.digitize, this value gets index 0, which becomes -1 after subtracting 1. This negative index will cause issues in the binning loop (lines 167-174 of conditions_plot.py) where it's used as 'idx_bins == ii'. Consider starting bins slightly below the minimum value, e.g., 'np.nanmin(data_to_be_binned) - bin_size/2' or handling the edge case explicitly.

Suggested change

bin_indices = np.digitize(data_to_be_binned, bins=bins, right=False) - 1

bin_indices = np.digitize(data_to_be_binned, bins=bins, right=False) - 1

# Guard against values equal to the minimum falling below the first bin (index -1)

bin_indices[bin_indices < 0] = 0

Fixed in commit 70ae4fd. Added guard to prevent negative indices: bin_indices[bin_indices < 0] = 0 after the digitize operation. This ensures values equal to the minimum bin edge are correctly assigned to index 0.

+                if len(date_groups) == 1:  # Only add colorbar if single group
+                    cbar = plt.colorbar(scatter, ax=ax2)
+                    cbar.set_label(color_var)


When using color_var with multiple date groups, no colorbar is created (line 272 condition is False). This means users cannot see what the color values represent. Consider either: (1) adding a single colorbar for all groups combined, (2) documenting this limitation in the docstring, or (3) raising a warning when color_var is used with multiple groups.

lets do a single colorbar for all groups combined

Implemented in commit 70ae4fd. Changed the colorbar logic to create a single colorbar for all groups when color_var is used. The colorbar now uses the first scatter collection and displays outside the loop, showing the color scale for all groups combined.

+
+        fig, axes = conditions_plot(time_list, start_date, end_date, ofname='test_output.png')


Variable fig is not used.

Suggested change

fig, axes = conditions_plot(time_list, start_date, end_date, ofname='test_output.png')

conditions_plot(time_list, start_date, end_date, ofname='test_output.png')

write as _, _ = conditions_plot

Fixed in commit 70ae4fd. Changed to _, _ = conditions_plot(...) pattern to explicitly indicate both return values are intentionally unused.

…onditions_plot.py

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. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
