( (Axis) ( (ChartWithAxes) currentChart ).getAxes( ).get( 0 ) ).setCategoryAxis( true );
		}
		else
		{
			
			
			currentChart = ChartWithAxesImpl.create( );
			currentChart.setType( TYPE_LITERAL );
			currentChart.setSubType( sNewSubType );
			( (ChartWithAxes) currentChart ).setOrientation( newOrientation );
			currentChart.setDimension( getDimensionFor( sNewDimension ) );
			( (Axis) ( (ChartWithAxes) currentChart ).getAxes( ).get( 0 ) ).setOrientation( Orientation.HORIZONTAL_LITERAL );

					.get( 0 ) ).getAssociatedAxes( ).get( 0 ) ).setType( AxisType.LINEAR_LITERAL );
			
			currentChart.setBlock( helperModel.getBlock( ) );
			currentChart.setDescription( helperModel.getDescription( ) );
			currentChart.setGridColumnCount( helperModel.getGridColumnCount( ) );

				currentChart.getInteractivity( )
						.setEnable( helperModel.getInteractivity( ).isEnable( ) );
