Is it possible to implement it by programming as in the picture above?
I'm aleady using cluster false but graph is centered.
If I understand correctly, you want to have the red showing behind the blue bar? Or do you want to have another bar which is then with a dotted line?
From the docus: https://www.amcharts.com/docs/v3/reference/amgraph/#clustered_property
So depending on what you want to do you maybe have to calculate an entry on the same x-axis position (I guess it's a date) as the blue bar and then use clustered = false
Also maybe you have to do it in a stacked way: https://www.amcharts.com/demos-v3/stacked-column-chart-v3/
