I can’t change the color of the title of a pie chart in perspective.
(other properties such as font size i am able to change)
Yeah it doesn’t look like there’s any real way to do this. The color is currently being overridden internally. I’ll add this to our existing ticket to fix up the pie chart component.
For posterity, the 8.0.9 nightly build available today provides a dedicated title color property.
Is there a way to size the Title text separate from the labels?
There is not. If you need that additional granularity you’ll want to omit the title from the Pie Chart and instead apply your own Label as a separate component.
