How to get Casting camber for cast in place segmental bridge?

Suppose we want to get the camber for the segments highlighted in red below. The construction direction is from right to left (-DX). Thus, node 20 is a start node.

The vertical displacement at the final stage is as shown below.

General Camber Control setting as shown below. 

Construction camber graph as shown below. Note that node 20 (or start node) is located at the left side in the horizontal axis and node 9 (or end node) is at the right side.

If we check on the 'Set start point zero' option,

The camber is calculated with respect to the node 20 (or start node).
