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.
chart/org.eclipse.birt.chart.engine/src/org/eclipse/birt/chart/internal/datafeed/DataProcessor.java
rsw.getSubset( triggerExprs, aggExp ) );
					seOrthogonalRuntimeSeries.setSeriesIdentifier( seOrthogonalDesignSeries.getSeriesIdentifier( ) );
					sdOrthogonal.getSeries( ).add( seOrthogonalRuntimeSeries );
				}
			}
		}
		else
		{
			
			Object[] oa = rsw.getMergedGroupingBaseValues( iBaseColumnIndex,
					baseSorting );
			List baseValues = (List) oa[0];
			List idxList = (List) oa[1];
			final int maxCount = baseValues.size( );
			
			
			Object[] baseData = populateSeriesDataSet( seBaseRuntimeSeries,
					new ResultSetDataSet( baseValues,
							rsw.getColumnDataType( iBaseColumnIndex ) ) );
			
			Series seOrthogonalDesignSeries;
			Series seOrthogonalRuntimeSeries;
			SeriesDefinition sdOrthogonal;
			List orthogonalDataList = new ArrayList( );
			for ( int i = 0; i < axaOrthogonal.length; i++ ) 
			{
				elSD = axaOrthogonal[i].getSeriesDefinitions( );
				for ( int j = 0; j < elSD.size( ); j++ )
				{
