Glad to here you succeded in syncing (hope it wasn't to much work )

When I removed the TYPE template parameter from GraphElementCtrl i Noticed I could simplify things and define default types (that don't need templates)

You should have used :

class GanttBarSeries : public GraphSerie

Since CustomDataSource was renamed GraphSerie
SimpleJobSerie is just an example of a job serie

class GanttBarSeries : public SimpleGraphSerie {

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() ;

I will look into this, obviously there is a problem ...
