Gantt chart with bar chart problem

[roloszab]

Hello All,

I want to create a Gantt chart with more values in one line separately. So it means a task contains more timeslots, but in between the offset should be blank (white). Here you can see all details:

Duration:

RangeMax(Above(Max(End),0,RowNo())) - RangeMax(Min (Start),RangeMax(Above(Max(End),1,RowNo()-1)))

Offset:

If(IsNull(Above(Only(JobName))),Min(Start),RangeMax(0,Min(Start)-RangeMax(Above(Max(End),1,RowNo()-1))))

Do you have any idea how should I modify the programs / customizings?

Thank you for all answers and helping!
