Bug in sending email subscription report: 2 scales make charts wrong

Hi everyone,

I noticed a bug that reproduces everytime I use the email subscription:
The email has a different scale for the bar on the left, and thus the whole figure is wrong. Please see below picture, 41 is way above 74.
I can report a bug on github but don't know where to!

By the way, the problem in email subscription with Chinese not being sent properly is solved, many thanks!

:wave:t2: Metabase version?

0.47.9 with MariaDB on a SYnology NAS

thanks, any way you can repro this with the sample database?

I‘m sorry I deleted the sample database and not too sure how to reinstall it... But i'll get the logs and share

I believe you are experiencing this issue:

Can you please check and confirm?

Hi @zoltan I am really sorry, I wasn't able to send emails anymore and it took me 2 months to figure out it was because security had to move from TLS to STARTTLS :melting_face:

Anyway, I have tested as you said and this is not like the bug you mention. In none of my charts is the Split y-axis when necessary checked.

Besides, my problem is not for exporting a chart in png (I have double checked and they work fine), but to export a whole dashboard, and in this case the charts within the dashboard start to behave weird and erratically.

Here's my DB info:

Thanks for taking a look. If you still this problem on a recent version, best course of action would be to try to reproduce it on the sample database. You can bring it back if you have deleted it, see:

OK I have restored the DB (and upgraded to the latest Metabase 0.48.7)
there are actually still issues with the email function, but not the same as before :slight_smile: :

when you stack columns, the scales are not wrong anymore, but the email de-stacks them.
Above is the view from the received email, below the one from the dashboard (?!)

  1. BTW, some questions are randomly omitted from the email, I have to reload the questions into the dashboard for them to be taken into account.
