Dera Thiansu,
unfortunately, the brew version of xcrsyden is not working anymore in MacOs, you can try try install it from MacPorts.
Vesta is a good alternative as it is free and it reads xsf file as xcrysden:

With gnuplot you can plot 1D and 2D data, isosurfaces are not supported, so you need to plot integrated quantity:
Direction= "123" not allowed.

In order to use gnuplot you can have a look to the guide:
http://www.gnuplotting.org/plotting-data/

as basic plot for 1D:

Code: Select all

>gnuplot
plot "data" u 1:2 w l
for 2D

Code: Select all

splot "data" u 1:2:3 w l
2D data can be also plotted as contour maps.

Best,
Daniele
