Use the "Cut Grid" plugin with nPointsV=1 and ConnectPoints=0. This will 
evaluate the solution on a series of points along a line, and you can 
then either visualize the 2D plot in Gmsh (Options->View->General->2D 
space plot) or export it to view it in gnuplot, excel, etc. (with 
View->Save As->Text).

For more complicated distributions of points (not just along a line) you 
can use the "Cut Parametric" plugin.
