ZigZag indicator only drawn in the background?

 

Hi guys,

is there a possibility to modify the code of the ZigZag indicator that the lines are drawn in the background behind the candles? I didn't find a solution how to do it with the buffers.

I don't want to set the chart on foreground because I need the lines and objects to be in the foreground. It's just the ZigZag lines I want to see behind the charts.

 
i think you need to draw the candles over the ZZ
