290.35 14.14
Each composition has its own temperature row and pressure row
which will make a curve when I plot them normally. Now I want to plot all the compositions and its respective curves in 3D plot environment. Attach is this figure for what I am look for as an end result, Can someone help me

What is the aim of attaching the same figure twice? you can also post your data as one matrix with 3 columns

If M is your matrix with three column
comp=M(:,1);
temp=M(:,2)
pres=M(:,3)
plot3(temp,comp,pres)
grid

Make your matrix as below
M=[90 279.25 2.7
90 283.15 4.18
90 284.75 5.8
90 285.85 7.5
90 286.85 10.82]
