Hello everyone! I have developed my own solver using OpenFOAM 4.1 and during calculation, I want to report velocity and pressure on single line using singleGraph function of OpenFOAM. However, I am not able to use it with my own solver. If I try a sample case with simpleFoam, singleGraph is working. So, I think I correctly edited controlDict file.

What I guess, I forgot to add one library to the make file of my own solver but I couldn't find it which library is required for simpleGraph. Can you help me? How can I use singleGraph for custom solver?

Thanks!
