amCharts to Perspective XYChart Properties Reference

I've found myself needing more control of the built-in charts and have read in other threads that the charts in Perspective are from the amCharts library.

My current issue is trying to turn off the text in a horizontal scroll bar, I've found that I can add "fontSize: 1px" to make it very small, which does the job I guess. When applying other properties however, they don't seem to work (I tried to change the bar thickness with "height" and "minheight").

Before:


After fontSize: 1px

What I was expecting with height and minheight (from amCharts docs):

My question is mainly: is there a way to know what to try where in the Designer property editor based on the amCharts documentation? I feel like there is a lot of functionality that is missing from the default chart config and I'm having trouble figuring out what to add to the properties tree.
