With the June Desktop update, we now support updating your chart fonts to any of the fonts we currently support for textboxes. Learn more in our blog: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-june-feature-summary/#fonts
We will be working on allowing you to use your custom installed fonts as well in a future release.
Thanks for submitting. We are looking to make some improvements in this area.Anonymous commented
