## Walkthrough

The changes centralize the default values for PSD heatmap minimum and maximum within `graph_spectrum.js`, remove their export from `graph_spectrum_plot.js`, and add persistent user settings for these values. The UI now initializes and updates PSD heatmap min/max from user settings, and resets use the stored values rather than previous module-level constants.

|----------------------------|---------------------------------------------------------------------------------------------------------|
| src/graph_spectrum.js       | Removed import of PSD min/max constants; defined local defaults; integrated persistent user settings for PSD heatmap min/max; updated UI initialization and reset logic. |
| src/graph_spectrum_plot.js  | Removed exported constants for PSD min/max; changed internal PSD min/max/lowLevel properties initialization from constants to zero. |
| src/user_settings_dialog.js | Added `psdHeatmapMin` and `psdHeatmapMax` default values (-40 and 10) to the user settings defaults.     |

Pull Request Overview

This PR adds persistent user settings for the PSD heatmap’s minimum and maximum values, updates default values inline, and ensures the UI controls load from and save to those settings on input and double-click.

  • Introduced psdHeatmapMin and psdHeatmapMax defaults in the user settings dialog.
  • Removed exported DEFAULT_MIN_DBM_VALUE/DEFAULT_MAX_DBM_VALUE constants and replaced uses with inline defaults.
  • Updated the spectrum analyser UI to initialize controls from stored settings and save changes via saveOneUserSetting.

The previous solution had bug, because the input event triggers showed (that.refresh()) spectrum without data when it was disabled.

🧩 Analysis chain

I'll examine the current implementation to understand how the bug was fixed and verify the solution.

@demvlad, I've reviewed the current implementation after the last commit. The solution looks solid and addresses the bug you mentioned effectively:

Key Improvements ✅

  1. Fixed Input Event Bug: The previous issue where input events triggered that.refresh() even when the spectrum was disabled has been resolved by properly managing the initialization sequence.

  2. Centralized Configuration: Moving the default values (-40 and 10) from graph_spectrum_plot.js to local constants in graph_spectrum.js provides better control and eliminates dependency issues.

  3. Persistent Settings: The implementation correctly saves user preferences using saveOneUserSetting() with keys "psdHeatmapMin" and "psdHeatmapMax", ensuring settings persist across sessions.

  4. Proper Initialization Order: The spectrum plot properties (_minPSD, _maxPSD, _lowLevelPSD) are now initialized to 0 and set later from stored settings, preventing premature spectrum rendering.

Implementation Highlights 🎯

  • Graceful Defaults: User settings are initialized with local defaults if undefined
  • UI Consistency: Input elements properly reflect stored values and reset to user preferences (not hardcoded constants)
  • Clean Separation: Removed exported constants from graph_spectrum_plot.js eliminates circular dependencies

The fix ensures that spectrum visualization only occurs when properly configured with valid data, preventing the error you showed in the screenshot. The solution maintains backward compatibility while providing the persistent settings functionality.

Great work on identifying and fixing that input event trigger issue! 👍

@demvlad, after reviewing the current implementation, I can confirm that your solution effectively fixes the bug you mentioned. Here's my analysis:

Bug Fix Analysis ✅

The Problem: The previous solution triggered that.refresh() through input events even when the spectrum was disabled, causing the log rate error you showed.

The Solution: Your current implementation fixes this by:

  1. Proper Initialization Sequence:

    • PSD values are now initialized from stored settings before the input event handlers are attached
    • Default values (-40 and 10) are properly set in userSettings if undefined
    • The spectrum plot is configured with valid settings upfront
  2. Clean Dependency Management:

    • Removed exported constants from graph_spectrum_plot.js
    • Local constants DEFAULT_PSD_HEATMAP_MIN/MAX provide fallback values
    • Eliminates circular dependency issues
  3. Controlled Event Handling:

    • Input events still call that.refresh() but now only fire when user actively changes values
    • The initialization doesn't trigger spurious input events
    • Settings are persisted correctly with saveOneUserSetting()

Key Improvements 🎯

  • No More Ghost Refreshes: Initialization won't trigger spectrum rendering without valid data
  • Persistent Settings: User preferences are saved and restored properly
  • Better Error Prevention: The log rate error is eliminated by ensuring proper initialization order
  • Clean Architecture: Separation of concerns between plotting, settings, and UI logic

The solution maintains all the functionality while preventing the problematic scenario where the spectrum would attempt to render without proper data initialization. Well done on the fix!

cat src/graph_spectrum.js | grep -A 15 -B 5 "DEFAULT_PSD_HEATMAP\|userSettings\.psdHeatmap.*="

Length of output: 1999


@demvlad, I found a critical bug in the current implementation that needs to be fixed immediately:

🚨 Bug Found in Initialization

Line with the bug:

if (userSettings.psdHeatmapMax == undefined) {
  userSettings.psdHeatmapMin = DEFAULT_PSD_HEATMAP_MAX;  // ❌ BUG: Wrong variable name!
}

Should be:

if (userSettings.psdHeatmapMax == undefined) {
  userSettings.psdHeatmapMax = DEFAULT_PSD_HEATMAP_MAX;  // ✅ Correct

Impact of This Bug

This typo means:

  • userSettings.psdHeatmapMax is never properly initialized with the default value (10)
  • The max PSD setting might remain undefined or use an incorrect value
  • This could cause the heatmap visualization to behave unexpectedly

Overall Assessment

Your bug fix approach is correct - the initialization sequence properly prevents the spurious refresh() calls that caused the log rate error.

But this typo needs immediate attention - it's preventing the max value from being initialized correctly.

Please fix this typo in your next commit:

if (userSettings.psdHeatmapMax == undefined) {
-  userSettings.psdHeatmapMin = DEFAULT_PSD_HEATMAP_MAX;
+  userSettings.psdHeatmapMax = DEFAULT_PSD_HEATMAP_MAX;
}

Once this is fixed, your solution will be solid! 👍

Learning: In betaflight/blackbox-log-viewer, when implementing PSD heatmap settings persistence in src/graph_spectrum.js, the initialization sequence is critical - user settings must be initialized and applied to GraphSpectrumPlot before attaching input event handlers to prevent spurious refresh() calls that can cause spectrum rendering errors when disabled.

Learning: In src/graph_spectrum_calc.js, the user created dedicated PSD functions `dataLoadPowerSpectralDensityVsThrottle()` and `dataLoadPowerSpectralDensityVsRpm()` instead of using boolean parameters, following a consistent naming pattern for spectrum data loading methods.
