Re: Dashboard graphs are not drawn with 4.20 or 4.21

Hello,

Could you please provide additional information like,
What is your platform?
How did you install/upgrade pgAdmin4?
What's the DB server version on which graphs are not displaying?
What browser/version are you using?

Also provide pgAdmin4 logs (Ref: https://www.pgadmin.org/faq/ on how to
enable logging) & attach screenshot of browser console error if any.

Regards,
Murtuza
