Graphing function broken,

diyhouse · 5 July 2026 07:58

I recently ( a few days ago ), did a full update,.. 1st one in probably 6 months, to catch any updates and fixes.

However I have now discovered that graphing functions seem to be broken.

I have tried rebooting ( 1st reboot in 324 days ,.. darn ), full emoncms updates,.. aligning with the stable branch, doing updates, another reboot… But As yet nothing seems to work,..

If I try to enter the graph menu on my PC,.. I get the following error

Fatal error: Uncaught Error: Call to undefined function load_js() in /var/www/emoncms/Modules/graph/view.php:24 Stack trace: #0 /var/www/emoncms/core.php(101): include() #1 /var/www/emoncms/Modules/graph/graph_controller.php(49): view() #2 /var/www/emoncms/core.php(81): graph_controller() #3 /var/www/emoncms/index.php(257): controller() #4 {main} thrown in /var/www/emoncms/Modules/graph/view.php on line 24

At the top of the screen,.. no graphics, just this text.

Not sure if this is related,.. but in the following thread I had some issues with a previous update where I had modified one of the components… this was align start of week as Sunday..

https://community.openenergymonitor.org/t/cannot-upgrade-via-admin-pages/29004

Any thoughts as to what might have gone wrong, ??

my components are at the following levels.

Hello @diyhouse it looks like you have an incomplete update, in particular your version of core is behind, it should be on 11.15.15. Could you try running update again?

diyhouse · 5 July 2026 14:23

Hi Trystan,.. Tx For the ‘out of hours’ response,

Ran the update as you requested:-

Does this have anything to do with the ‘git stash’ stuff I did, to preserve Sunday as start of week?

KR…

Yes thats it

As you have local changes you will need to merge the upstream changes into your local branch, using:

git config pull.rebase false
git pull

diyhouse · 5 July 2026 19:58

Tx Trystan,…Got there with a few additions,…

to complete update I needed to

cd /var/www/emoncms/Modules/feed/engine
followed by:-
git config pull.rebase false
git pull
git stash
git config pull.rebase false
git pull
git stash apply ;to write back updates

Initially the git pulls were failing as follows:-

error: Your local changes to the following files would be overwritten by merge:

Aborting

hence I injected the git stash,.. which seems to have saved my edits…

and an additional

git config pull.rebase false
git pull
     and :-
git stash apply ; to write back updates

The final git pull then seems to update all of the components, with a whole load of php js css json files being update in the blink of an eye… followed by the git stash apply

on refreshing the emonpi components screen,.. emoncms core is at 11.15.15

And the graph interface has a whole new look and feel…

what new toys are here,.. I will explore..

How do I maintain future updates,.. is it essentially as I have discovered above,.. or can it be automated,.. I only ask,… as my git experience is very limited..

Many tx for your help Trystan
