Human UI "advanced" chart formatting and trouble shooting

Have people been able to achieved advanced formatting for chart inside Human UI, when I said advanced I mean using number and percentage for a pie chart, while having the numbers formatted as “30,000” for example. And have gauge chart change color conditionally, based on percentage? I have just started playing around with it and haven’t figure out how to.

On a related note, has anyone, while using Human UI, not able to invoke any dialog window in Rhino, for example while I’m running my grasshopper script, and now i try to use insert or ViewCapturetoFile, dialog window will not come up. The “user key/value” tab inside property will also disappear.
