You should be able to do these kinds of things with the "Cut Grid"
and/or the "Cut Parametric" plugins (available in the "Plugin" menu when
right-clicking on a view button).

If you set "ConnectPoints" to zero in these plugins, you can then plot
the data in 2D graphs by selecting "2D space plot" in
Tools->Options->View->General. You can also export the data in order to
visualize it with other tools by using "View->Save As".
