Bug 181706 Sorting Data by X values doesn't work without grouping
Using the 2.2M5 designer , I simply want to sort the data of the X Series in a Line Chart. I go into the Sort and Group pop up in the chart wizard and select ascending, but it doesn't affect the result. (style ordered same as the result set) If i define a dummy grouping (no interval) it is then working.

maxCount,
						(List) idxList.get( groupIndex ),
						userDs );
				( (Object[]) orthogonalData[i] )[3] = ds;
			}
			
			
			fillSeriesDataSet( (IDataSetProcessor) baseData[1],
					seBaseRuntimeSeries,
					(DataSet) baseData[0] );
			int odx = 0;
			
			for ( int i = 0; i < axaOrthogonal.length; i++ ) 
			{
				elSD = axaOrthogonal[i].getSeriesDefinitions( );
				for ( int j = 0; j < elSD.size( ); j++ ) 
				
				
				{
					sdOrthogonal = (SeriesDefinition) elSD.get( j );
					String aggExp = rsw.getLookupHelper( )
							.getOrthogonalAggregationExpression( sdOrthogonal );
					for ( int k = 0; k < iGroupCount; k++ ) 
					
					
					
					{
						Object[] odata = (Object[]) orthogonalData[odx];
						seOrthogonalRuntimeSeries = (Series) odata[2];
						fillSeriesDataSet( (IDataSetProcessor) odata[1],
