You could use one of the "Cut" plugins (e.g. Plugin(CutGrid)) to extract the data you want on points along a line, then plot this as a 2D graph, time-dependent or not...

For example, I have a result field C(x, y, z=0, t) written to post.msh and wish to plot C(x, y0, z0=0, t0) vs x or plot C(x0, y0, z0=0, t) vs t. Is it possible (either with my version or the current one)?
