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
ScriptHandler.callFunction( sh,
				ScriptHandler.AFTER_DATA_SET_FILLED,
				seRuntime,
				ds,
				rtc.getScriptContext( ) );
	}
	/**
	 * Fill series with populated and adjusted dataset.
	 */
	private void fillSeriesDataSet( Chart cm, Series seRuntime,
			IResultSetDataSet rsds ) throws ChartException
	{
		fillSeriesDataSet( cm, seRuntime, rsds, null, null );
	}
	/**
	 * Fill series with populated and adjusted dataset.

	private void fillSeriesDataSet( Chart cm, Series seRuntime,
			IResultSetDataSet rsds, String[] userKeys,
			IResultSetDataSet userRsds ) throws ChartException
	{
		final ScriptHandler sh = rtc.getScriptHandler( );
		IDataSetProcessor idsp = null;
		try

			idsp = PluginSettings.instance( )
					.getDataSetProcessor( seRuntime.getClass( ) );
