Chart legend incomplete BO XI 4.1

Dear all,

I am struggling with a point which should be an easy one as it used to work perfectly in previous versions...

I have a chart legend with quite a lot ot items but I can not manage to "split" the legend in 2 or more lines.

Automatically, all criteria are on one line and each headings are otherwise cut (wrap) otherwise some do not appear (Truncate).

I am working under BO XI 4.1 (Webi).

I can provide further details if needed,

Thank you for your help,

Best regards,

Audrey
