Thanks Barry, that works fine. Any chance to access the reordered matrix behind 
the plot?

   You can save the plot in an image file that does not require X. For example

    -mat_view_ordering draw:image:filename

   Several image formats are available.

I'm saving a petsc mat to file and loading it into python to make a spy plot of 
its sparsity pattern, so far so good.

Now I would like to compare with a reordened pattern, say rcm. I've notice the 
option -mat_view_ordering draw, but do not have X Windows on this machine. What 
is the recommended way to get the reordened matrix for inspection?
