Bug 194727 Pyramid chart with 2d+ dimension should like a pyramid
Pyramid chart in 2d+ dimension should like a pyramid, rather than a triangle with depth effect. In addition, pyramid in 2d+ should like itself in 3d as well. Take a look at attached screenshot to compare the charts.

			tre.setTextPosition( Methods.getLabelPosition( lp ) );
			tre.setLocation( lo );
		}
		else
		{
			tre.setBlockBounds( bo );
			tre.setBlockAlignment( null );

		tre.setLabel( laDataPoint );
		tre.setAction( iTextRenderType );
		if ( _dc == null )
		{
			dc.addLabel( tre );
		}

			_dc.addLabel( tre );
