Plot over line is not working
 

Hello All,


I have simulated one of the tutorials of OpenFOAM6 and tried to view it using paraview5.6.0. It is working fine.



Now I want to use the plot over line utility to plot the temperature graph. When I select my reference axis and click apply, an empty graph pops up.


I mean I am not able to see the line in the graph.


I don't understand why is this happening. Can anyone please help me with this?


Thanks
