Is there a way to change the date format on the x-axis of the Analyse Charts?
At the moment it seems to be formatted month-day, which is awfully American… 
I wondered whether it had something to do with Regional Settings, but these are correct for my area, where we would usually use day-month-year
Did you ever find a fix for this ?
Nope, but then I’m still on OH2 for my production system so I haven’t tried looking any further…
Thanks.
I’m doing exactly the same.
It’s a steep but interesting learning curve after always using config files for everything.
If I find an answer I’ll post it here.
I’m on OH3 (Snapshot #2206) and my analysis chart looks like that:
I’m using a German language setting, changing it to UK English didn’t show to date as in the OP either.
Strange. I’m on the 3.0.1 Release Build.
runtimeInfo:
version: 3.0.1
buildString: Release Build
locale: en_GB
Analyse charts still have US date formatting.
If I run locale in a terminal on my OH3 device:
LANG=en_GB.UTF-8
LANGUAGE=en_GB:en
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=
Which all seems correct? Not sure what else to look at.
Not many countries use month-day format.
Why not use ISO format?
Or better still pick up the format from the machine openhab is running on and then everyone would be happy.

Looks like we have an answer for the moment: no, this can’t be changed.
