[Wien] problems with plotting the diagrams of DOS, electron density using rhoplot without gnuplot

[Zhou Bing]

Dear all,
I tried to plot electron density for TiC again from beiginning without -c and -p flags as Prof. Peter Blaha suggested. Although I have the files such as :rho1, :rho2, tic.rho, tic.rho_onedim (empty) and tic.rhopw (empty), it seems there is no softwware of "gnuplot" on my directory, thus, I failed in producing rhoplot.ps file after using the command of "rhoplot".
Therefore, it seems that I can not produce the plot of electron density through w2web or "rhoplot" due to lack of "gnuplot".
Please give me further suggestions and instructions about how to plot the DOS and electron density diagrams, thank you in advance!
Bing

PS: tic.rho is the original data for plotting the electron map?

So I run "x lapw1" as suggested by w2web and checked tic1.vector again, this time it is not empty anymore although my computer can only display strange characters of the file on the screen;
