It is possible to make a Tracking Gantt? I mean having 2 TimeItems for each node differently coloured and which can overlap? Just like MS Project style.
I am not entirly sure what you mean with “tracking” in this case, but it safe to say that one way or the other you can do anything that MSProject can do.
You might need to use UserDrawn time items, you might need to use time items on different drawing layers, but rest assured that you can do everything in MSProject. If you want a specific answer please explain your need in greater detail.
