In FLUENT, in the Surface menu, select line option. You can create a line by defining the co-ordinate points. Then using the plot menu you can plot any quantity along that line.

I prefer exporting the data to a postprocessor (Tecplot in my case) to visualize the data.

Hope this helps!

Unfortunately Tecplot is not a freeware. If you are in academia you might find out if your university owns licences. There might other similar CFD postprocessing softwares too.

I agree Tecplot is difficult to learn initially but in my experience is a good postprocessing software for CFD.

You can google "Tecplot demos" etc. and you will definitely find some help on how to use this software.
