GCOverrides

While it is rather complicate to make Garmin responding to bug reports or to feature requests regarding Garmin Connect Web, it is often possible to make the changes ourselves, locally. A feature of the Chrome browser, called Local Overrides, allows it - you can customize not only the look of the pages, but in some cases, and to certain extent, even the functionality.

When reading the forums, I saw many requests, where the overrides could be used, and decided to test whether it could be done. After some testing I decided to share the results with the community. 

The installation of the overlays is easy - it is sufficient to download the file archive, unzip it into a folder, and then assigning and enablig it in Chrome DevTools. Detailed description of the functionality, and step-by-step installation instructions are available on GitHub. The only inconvenience is, that to keep the GCOverrides active, the DevTools pane or a window need to stay opened. The best way of doing so, is detaching them from the current page as a separate window, and minimizing them.

Recently, the Local Overrides work also on the latest Microsoft Chromium Edge.

The installation process is explained in details in the README file

Current Features (GCO v1.20)

  • Weight - 6 Months Report - brings back the 6 Months report plotting all weight data within the 6 motnhs period (not only monthly averages like the 12 Months report does) Note: as of 2020/04/03 I noticed a new look of the Weight page in GC, and this feature of GCO does not work with it. However, since it still seems to be just an intermediate version, suffering some problems, I'll wait till Garmin fixes the bugs, before trying to add the 6 months report again.
  • Activity Overlays bugfix - adds missing overlays and their labels on zoomed graphs on the Activity pages
  • Floors per Min bugfix - fix of the incorrect pace on the native GC Floors Climbing Activity page 
  • Configurable Sleep Goal - see the chapter Setings in README.md for instructions
  • Conversion of Calories to kilojoules on the Calories In/Out page and on the Dashboard; needs to be enabled in the GCO Settings
  • Adjustable Y-axis on Graphs - turns the majority of graphs to have adjustable Y-Axis (with the help of selecting a rectangle of the current graph). Please note, that due to the compression of JavaScript files and the use of numeric chunks in GC, this feature may require frequent updates, and/or may not work for everyone. Searching for a more stable hack.
  • Panning of Graphs - the user can press the Shift key and drag the mouse in order to pan a zoomed graph (same limitations as at the previous feature)
  • Exportable Graphs - additional Export menu at zoomed graphs allowing the export of graphs as images or PDF
  • Enhanced Graph Tooltips - Distance added to all time-based activity graph tootips; improved formatting of tooltips on zoomed versions
  • Hiding Golf - optional hiding of Golf from the Side Menu and from the Gear Menu;
  • Hiding Model-Based Badges - badges designed only for exclusive watches may be hidden from the list of available badges 
  • Enabling manual date input in Reports - in the native version, on the Progress Summary page of Reports, the date can only be picked from the Calendar. Now you can enter it manually.
  • Diving Distance - information about the aerial distance between the entry and the exit locations of a dive
  • Step Counts for Activities - on the pages of activities of the type Run and Walk, the count of steps done during the activity is displayed
  • ... more to come

For details, please have a look at the CHANGELOG

(I'll be updating the list of features above, when new ones will be added)

  • OK, I see. I'll try to do somethinng with it, but it may take a while. I looked at it - although the report is gone, the detailed data in the backround is still availale, so I shoud be able to find a way, just it will be a bit more complicated than originally, with the report being just hidden.

  • It sounds like a bit of an undertaking. I wouldn't go crazy over it if it's too much trouble. Like I said, I can create a graph from my access database. 

    Incidentally, I have kept a record of pretty much every activity I have done since 1974. Back then, it was in a paper diary but soon was transformed into a dbase III database and then moved to Access when it became more of a standard. I just checked and my Access database has 9,647 records.

  • Another update after a longer time: Version 1.15 - added Detailed 6 Months and Yearly Graphs - instead of the default monthly averages, all data is shown (daily values)  on relevant 6 Months and 1 Year graphs on the Reports page. See an example below for the Pace Report

  • Hi Trux.

    Not seeing the changes on my side. I went to average pace and although the cursor changed and the overrides window was showing, the data didn't look any different for me.

  • Does the label on the top of the page tell GCOverrides v1.15? Did you copy all the new files, or just some of them?

  • No it doesn't have a title at all. What I did was delete my previous version and extract the GCO-master folder to where the old folder was.

  • Actually, I see where it says GCO overrides v1.15 now but the data isn't any more granular.

  • Actually, I see where it says GCO overrides v1.15 now but the data isn't any more granular.

    Not sure if I understand what you mean by "data isn't any more granular" - does it mean it works now for you? Or that it worked before, and now it stopped? Maybe post a screenshot, that I see better what you mean.

  • With and without overrides. Data is the same. I expected to see a lot more dots like you showed in your image.

  • I expected to see a lot more dots like you showed in your image.

    Yes, definitely, you should, unless you have just one activity per month. But even in such case, the dots are smaller on the 6 Months and 1 Year reports, with GCO, than on the default repeorts.

    Please have a look at the tab Overrides in DevTools - you may need to make the DevTools pane bigger, or better yet undocking it (through the menu under one of the triple dot symbols) to see it better. The Overrides tab then shows the list of active files - those are shown with a purple dot (see the screenshot from my browser, below). On the Reports page, the files 77.9aeb... and gauth-widget.js should have the purple dot. Especially the first one is important. If it is not active, we'll have to look deeper, but first let me know how it looks with this.
