well they do have an error message for it 080271: At least two fields should be specified.—Help | ArcGIS for Desktop but it must be buried under 'style'
but you can search Find symbols—ArcGIS Pro | ArcGIS for Desktop
and keep going round in circles..
I have found where you can do a pie chart in the Pop-ups, maybe this is what the error code is referring to. I can't seem to find any way to do the symbology as a pie chart or any reference in the help for doing a pie chart as a map symbol.
Jeremy, this is one of those Pro examples that I was talking about... perhaps the 'roadmap' or 'upcoming' would be akin to the 'not currently available' would be the useful addition in addition to 'issues addressed'. It is more a more forward looking approach and might save people time searching for something that is to come.
Jeremy- can you provide an update on timing for release? This is a big road block for us implementing ArcPro. The idea on the ideas page has said "reviewed" for a long time now.
Sorry for the delay Brett - just to let you know this was demo'd at the Road Ahead for ArcGIS Pro session at Esri UC 2019. So it's well in progress for the next release.
