Hello,
I am new to OF and gnuplot. I am working on the T3A flat plate case in tutorials of OpenFOAM. I was struggling a lot to plot graph of friction coefficient from simulation and experimental data using the default plot_file (creatGraphs.plt) provided with the tutorial. I looked on the internet for a solution but remained unsuccessful. So, after trying for some time, I got the graph correct so I decided to share it here for use of anyone else.

The trick is we have to edit...
