The Compaq Array Visualizer doesn't support the display of a non-uniform mesh.
The Intel Array Visualizer does support non-uniform meshes though (and also 2D plots for a list of x,y values). If you'd like to try it out you can get a free evaluation download at:

Note the Intel Array Visualizer isn't integrated with the debugger at this point (that feature will be part of the Intel Visual Fortran release).
