i have set of 2d plots (density of states (dos) of atomic layers) , want plot them in 3d plot show how dos changes @ each layer. data organized in file (3d_data) in following format

e1 ly1 dos11 e2 ly1 dos12 e3 ly1 dos13  e1 ly2 dos21 e2 ly2 dos22 e3 ly2 dos23 

so far have come following gnuplot script

set xlabel "energy - e_f (ev)" set zlabel "local dos\n(states/ev)" set xyplane 0 set view 60,50 set border 895 set style data lines set surf set yrange[0:20] noreverse nowriteback set zrange[0:0.8] noreverse nowriteback set xrange[-10:5] noreverse nowriteback splot "3d_data" u 1:2:3 t "spin up"
