Graphic drawing

Question

In the visual, 2 different graphics are given in a single frame (layout 1, 2). Both graphs are constrained by y 0: 7.

1. Data concerning the graph of the column (phonon distribution) "" ZrSbTe.ph_THz "and xmax = 0.885990 The data concerning the 2nd column graph are “ZrSbTe.dos_THz” and 2: 1 (Total), 3: 1 (Zr), 4: 1 (Sb) and 5: 1 (Te) ie the y-axis in the 1st column graph in the file, other columns in the file are taken as the x-axis in the graph. 70% area was used for 1st Chart and 30% for 2nd Chart. Let's get the same graph by paying attention to the colors. Let's load the gnuscript and the output graphic by making a 2 page PDF.

x-coordinates of column labels (you specify y coordinates)

Γ = -0.01
X = 0.13
L = 0.20
T = 0.22
W = 0.251
R = 0.34
X1 = 0.38
Z = 0.50
Γ = 0.575
Y = 0.67
S = 0.715
W = 0.835

Answer 1

Your final goal could be split into many different questions and "how-to-dos",... too many without any code and specific question. Keep in mind, for every keyword you can type help <keyword> in the gnuplot console to get some information. Check the gnuplot homepage and the PDF manual in the local doc folder. I assume you are new to gnuplot... check the following example as a starting point. If you have a specific question, please remember: questions always with code.

Code:

set ylabel "Frequency / THz"

set multiplot layout 1,2

    set size 0.7,1

    set rmargin 0
    plot for [i=2:5] $PH u 1:i w l lc "dark-grey", \
