You can go to the results, from XY data, ODB field output, put it on unique nodal, NT11, and from element/nodes, you select the nodes and hit plot, boom you have your curves!
watch this video for a better understanding, I recommend you not to skip to the last part as it is required to see how you select the variables for the output. Also, in the same playlist there are bunch of similar thermal videos that might help you!
