Unsolved Change brush of a specific bar in QBarGraph

[Ankit.Jain]

Hi,
So I am wondering if it is possible to change to QBrush for a specific bar in QBarGraph [3D Bar graph]??
I saw the change of theme possible via an example given, but I haven't found a way to change a single bars' color [I want that over a certain value, the bar should become red in color].

Also, i saw the slicing to 2D based on row and column. Is it possible to give an option to show the same graph as 2D aerial view w/o the gimmick of rotating to an aerial view??

Thanks
