Extract point values from line and reference them in expressions

Hi, it feels like a very simple question that I have, but I cannot figure out how to do it.

Let's say I have a plate that is heated on one side, so a temperature profile is developing across the plate. I now how to plot the temperature profile along a line (e.g. the center line) via a "Cut Line" data set. But how can I print the values of temperature that are shown in the plot to a table? I'm thinking of something like "print the temperature for 100 evenly distributes points along the cut line". There has to be a more sophisticated approach than to create 100 cut points and 100 derived values by hand.

Also, i want to call those table cells in expressions, subsequently. For a start, I'd be happy to know how to reference a table cell or a derived value in an expression in general.

Thanks in advance! -Jan
