Just the 2 issues and questions from today:
under system\variables\system\locale_format_override you can set your localisation (for me GE-CH)
this affects the nummers shown in tables, but not the sum on the graph or legends, see below: also the number format changes in the export function again.
somehow a same issue happens on exporting with umläut like ä to pdf, where it gets a ?
This issue is registeret in our bugtracking system and will be fixed in 5.1 which will be released shortly.
