Hi guys,

I need to develop some component similar to the nebula tree mapper

I have some similar functionality but when the user scroll any of the trees I want to draw some line which is part visible and some part hidden but in order to do that I should calculate the X coordinate to start drawing the line and it should change when the mapping goes up and down, similar to this image but only showing part of the line

Thanks in advance for you help.
