[Wien] About electronic density plots !

[zufengxia at sohu.com]

Dear all:
I am calculating a magnetic material based on WIEN2k_03, in the task of the density of electrons, I selected SUB parameter rather than ADD in order to generate the spin density plots, and so I obtained the file case.rho including the positive and negative values, after plotting the electron density in the rhoplot mode, the figure occured. the problem is
how to plot the +ive and -ive part of the electronic density in a different linear style?
