197    \subsection{Line profiles of 2D data}
198    It is possible to take slices or profile sections of 2d data using \mpl. To acheive this there are three major steps, firstly the solution must be smoothed across the domain using the \verb projector()  function.
199    \begin{verbatim}
200    proj=Projector(mymesh)
201    smthT=proj(T)
202    \end{verbatim}
203    The data must then be moved to a regular grid.
204    \begin{verbatim}
205    xi,yi,zi = toRegGrid(smthT,mymesh,200,200,width,depth)
206    \end{verbatim}
207    The profile can then be plotted by taking a slice of the data output \verb zi  .
208    \begin{verbatim}
209    cut=int(len(xi)/2)
210    pl.clf()
211    pl.plot(zi[:,cut],yi)
212    pl.title("Heat Refraction Temperature Depth Profile")
213    pl.xlabel("Temperature (K)")
214    pl.ylabel("Depth (m)")
215    \end{verbatim}
216    This process can be repeated for various variations of the solultion. In this case we have temperature, temperature gradient, thermal conductivity and heat flow \reffig{figs:dps}.

231  To visualise this data we are going to do three things. Firstly we will generate the gradient of the solution and create some quivers or arrows that describe the gradient. Then we need to generate some temperatur contours and thirdly, we will create some polygons from our meshing output files to show our material boundaries.  To visualise this data we are going to do three things.
