How to get nodal solution results?

How can I get the nodal solution results from single nodes? I made a thermal calculation but in the post processor I think I cant solve this issue. I installed ParaView also but I didn’t succeeded it until now to get the necessary function neither! Is there a quick solution for that in SimScale? My goal is to plot the nodal results vs. the coordinates of the nodes (the tool is actually irrelevant).
Thanks in advance for the answer.
