Hi,
I have managed to get a custom font to work via a JSON file, but this only works and displays for text boxes.
It doesn't work for any built in titles or visuals (below). Is this intented behaviour or is it something I need to add to the JSON?
Thanks
Liam

Hi @lherbert501,
Thank you for reaching out to the Microsoft fabric community forum.
In Power BI, custom fonts specified in a JSON theme file apply only to text boxes and not to built-in visual titles or other elements, which is the expected behavior. Power BI currently supports custom fonts only for specific elements like text boxes, and built-in visuals e.g., titles, axis labels are limited to default system fonts. No additional JSON settings can extend custom font support to these elements at this time.
refer to the official Microsoft Power BI documentation on report themes: https://learn.microsoft.com/en-us/power-bi/create-reports/desktop-report-themes
I hope this helps to resolve your issue. Feel free to reach out if you have any more questions
Regards,
Harshitha.
