@glyn.hudson, On my VM install, it is fine, on the EmonPi the changes are not appearing. Both main emoncms and graph repos are on master currently. Refreshed browser and rebooted on the EmonPi.
Ran an emoncms update twice as well.
I should also have said this comment relates to the graphID.
It did help, so I cleared browser cache and tested with a bit more concentration. It seems it’s these buttons that are not working:
These buttons are working:
Except this button 
seems to exhibit slightly unusual behavior - the start date is preselected like this…
And it seems to work as expected, until you press one of the (D,W,M,Y) buttons first, then you get this - missing start date. You can select a new start date but the graph does not update it’s time scale.
Sorry, I missed your post while writing my last post.
I tested again and all buttons seem to be working normally now.
The graph ID is also visible now.
Good progress, great work, you guys are great! 
These fixes are now in the Stable branch of the graph repo. Thanks again for your help everyone. Have a nice weekend
