[petsc-users] X-Viewer for complex numbers

[Smith, Barry F.]

   The PETSc Vec viewer just plots the real part of the vector. 

VecView_Seq_Draw_LG()

   to plot the imaginary part or phase etc you would need to write your own plotter (though you can copy some of the code, for example for VecView_Seq_Draw_LG())
