Re: [Gnuplot-info] How to represent a 2D plot in 3D

[Omamuyovwi A. <oma...@ya...>]

Many thanks to your response SIr.
I've been able to understand how to use the command better to suit my desired plot but I still have two questions.Using the script and data below, I got something meaningful but I do not understand why I had to first duplicate the set of value before the plot appear.Any comment to help me understand will be greatly appreciated. Secondly, is there a way to indicate a constant plot value for a column without necessarily indicate it in file? (Using my data as example, i had type the the constant value 3 in the second column of the data.)
#script
set terminal postscript eps enhanced color
set encoding iso_8859_1
set output 'omam.eps'
set ticslevel 0
set xlabel 'x'
set ylabel 'y'
set zlabel 'z'


colors = "red red red red red"
splot for [i=1:words(colors)] 'omam.dat' index i u 2:1:3 w lines lc rgb word(colors,i)
