Changed this as you suggested, but noticed that the template name is TStdGridAxisECtrl and not StdGridAxisECtrl; similar changes in other related lines

	typedef TStdGridAxisECtrl< GridAxisDraw >     StdGridAxisECtrl;
	typedef TStdLabelECtrl   < LabelElement>      StdLabelECtrl;
	typedef TStdLegendECtrl  < LegendElement>     StdLegendECtrl;
	typedef TStdBlankAreaECtrl<BlankAreaElement>  StdBlankAreaECtrl;
	typedef DynamicMarkerECtrl                    StdMarkerECtrl;

This needs package GraphSeries/SimpleJobSerie
//class GanttBarSeries : public CustomDataSource {
class GanttBarSeries : public SimpleJobSerie {

class GanttBarSeries : public GraphSerie

In Ctor, this was bit of a surprise. The first line worked fine before in both modes, now works in debug but crashes in release. Changed line works in both.

//GetElementY1GridAxisDraw().SetAxisInverted(); // crashes in release mode!
GetElementY1GridAxisDraw().GetCoordConverter().SetInverted() ;

Finally, noticed that now ScatterDraw package is needed, which wasn't the case earlier
